Arriving at the terminus, he climbed into a cab and issued directions to the driver. During the short ride from Curzon Street to the bank, he was reminded that Joseph Hansom, inventor and architect, had not only built the arresting Town Hall with its Classical colonnade, he had also registered the Patent Safety Cab, creating a model for horse-drawn transport that had been copied down the years. Birmingham was therefore an appropriate place in which to travel in such a vehicle.
Spurling’s Bank, one of the biggest in the Midlands, was in the main street between a hotel and an office building of daunting solidity. When he heard that a detective had come to see him, the manager, Ernest Kitson, invited Colbeck into his office at once and plied him with refreshments. A tall, round-faced, fleshy man in his fifties, Kitson was wearing a black frock coat and trousers with a light green waistcoat. He could not have been more willing to help.
‘The stolen money must be recovered, Inspector,’ he said.
‘That’s why I’m here, sir. Before we can find it, however, I must first know how it went astray in the first place. Inside help was utilised.’
‘Not from Spurling’s Bank, of that you can rest assured.’
‘Have you questioned the relevant staff?’
‘It was the first thing I did when I heard of the robbery,’ said Kitson, straightening his cravat. ‘Apart from myself, only two other people here have access to the key that would open the safe containing the money. I spoke to them both at length and am satisfied that neither would even consider betraying a trust. Do not take my word for it. You may talk to them yourself, if you wish.’
‘That will not be necessary,’ decided Colbeck, impressed by his manner and bearing. ‘I simply need to examine the key in question.’
‘It is locked in the safe, Inspector.’
‘Before you take it out, perhaps you could explain to me why the mail train was carrying such a large amount of money in gold coin.’
‘Of course,’ replied Kitson. ‘We abide by the spirit of the Bank Charter Act of 1844. Does that mean anything to you, Inspector?’
‘No, Mr Kitson.’
‘Then let me enlighten you. Currency crises are the bane of banking and we have suffered them on a recurring basis. When he was Prime Minister, the late Mr Peel sought to end the cycle by imposing certain restrictions. Strict limits were placed on the issue of notes by individual banks and the fiduciary note issue of the Bank of England was set at £14,000,000. Any notes issued above this sum were to be covered by coin or gold bullion.’
‘That sounds like a sensible precaution.’
‘It is one that Spurling’s Bank took to heart,’ explained Kitson. ‘We stick to that same principle and ensure that notes in all our banks are balanced by a supply of gold coin or bullion. A bank note, after all, is only a piece of paper that bears promise of payment. In the event of a sudden demand for real money, we are in a position to cope. Other banks have collapsed in such situations because they over-extended themselves with loans and had inadequate reserves.’
‘How much of the money stolen was destined for this branch?’
‘Over a half of it. The rest was to be shared between some of our smaller branches. None of us,’ he emphasized, ‘can afford to lose that money.’ Taking a key from his waistcoat pocket, he crossed to the safe in the corner. ‘Let me show you what you came to see.’
‘What about the combination number of the safe on the train?’
‘That, too, is kept in here.’
‘Have you not memorised it, Mr Kitson?’
‘I’m a banker, Inspector,’ he said. ‘I keep a record of everything.’
He opened the safe and took out a metal box that had a separate lock on it. After using a second key to open it, he handed the box to Colbeck. Inside was a slip of paper and a large key on a ring. Colbeck took them out and studied them carefully. Kitson watched in surprise when the detective produced a magnifying glass from his inside pocket to scrutinise the key more carefully. He even held it to his nose and sniffed it.
‘May I ask what you are doing?’ said Kitson, intrigued.
‘Looking for traces of wax, sir. That’s the way that duplicates are made. A mould is taken so that it can be used to produce an identical key. Not all locksmiths are as law-abiding as they should be, alas.’
‘And this key?’
‘It has not been tampered with,’ said Colbeck.
‘That is what I told you.’
‘I needed to check for myself.’
‘The only other set of keys is at the Royal Mint.’
‘My colleague, Sergeant Leeming, will be visiting the Mint this very day, but I doubt if he will find a lapse in security there. Their procedures are usually faultless. That leaves only a third option.’
‘And what is that, Inspector?’
‘A visit to the factory where the safe was made,’ said Colbeck, handing the key back to him. ‘Please excuse me, Mr Kitson. I have to catch a train to Wolverhampton.’
Victor Leeming’s day had had an abrasive start to it. When he reported to Tallis, he had found the Superintendent at his most irascible as he read the accounts of the train robbery in the morning newspapers. Seeing himself mocked, and misquoted, Tallis had taken out his anger on the Sergeant and left him feeling as if he had just been mauled by a Bengal tiger. Leeming was glad to escape to the Royal Mint where he could lick his wounds. His guide was a far less truculent companion.
‘As you see, Sergeant Leeming,’ he said, ‘security has absolute priority here. Nobody has sole access to the keys to that safe. There are always two of us present, so it would be impossible for anybody to take a wax impression of the key.’
‘I accept that, Mr Omber.’
‘There has been a mint here on Tower Hill since Roman times. Methods of guarding the supply of coin thus have a long and honourable history. Having learnt from our predecessors, we feel that we have turned the Royal Mint into an impregnable stronghold.’
‘There is no question of that,’ conceded Leeming.
He was fascinated by all he had seen, particularly by the thick steel doors that seemed to be fitted everywhere. Once locked, they were almost airtight, and would not buckle before a barrel of gunpowder. Charles Omber took a justifiable pride in their security arrangements. He was a short, stout, middle-aged man whose paunch erupted out of his body and tested the buttons on his trousers to their limit. Having been subjected to Tallis’s bellow, Leeming was grateful for Omber’s quiet, friendly, helpful voice.
‘What else can I show you, Sergeant?’ he asked.
‘While I’m here, I’d be interested to see the whole process.’
‘It will be a pleasure to show you.’
‘Thank you.’
Omber waddled off and Leeming fell in beside him. After passing the weighing room, where the amounts of bullion were carefully recorded, they went through some steel doors into the hot metallic atmosphere of the refining shop. Leeming brought up a hand to shield his eyes from the startling brilliance of the furnaces where molten gold was simmering in crucibles like over-heated soup. With long-handled dipping cups, refiners stood in their shirtsleeves before the furnaces to scoop out the liquid gold and pour it into zinc vats of water. Even those who were used to the heat and the noise had to use their bare forearms to wipe the sweat from their faces. Leeming was loosening his collar with a finger within seconds.
Charles Omber took him on to the corroding shop, where they were met with billowing steam from the porcelain vats in which the golden granules sizzled in hot nitric acid. It was like walking into a golden fog. When his eyes grew accustomed to the haze, Leeming watched the muscular men in their leather aprons and noticed that they all wore hats to protect them from the fumes. Interested to see every stage of the process, he was nevertheless relieved when they moved out of the room, enabling him to breathe more easily.
In the casting shop, with its arched furnace bricked into a wall, he saw the gold being melted again before being poured with utmost
care into the moulds of the ingots. Standing at his shoulder, Omber explained what was happening then took his visitor on into the rolling room, the largest and most deafening part of the establishment. The massive steam-driven mill, powered by iron wheels on each side, thundered ceaselessly on, enabling the brick-like ingots to be pressed into long strips from which coins could be punched.
It was when they moved into the coining shop that Leeming suddenly realised something. He had to shout above the metallic chatter of the machines.
‘I think I know why the robbers stole coin from that train,’ he yelled. ‘What is the melting point of gold?’
‘That depends on its source and composition,’ replied Omber, ‘but it is usually between 1,200 and 1,420 degrees centigrade. Why do you ask, Sergeant Leeming?’
‘They would need a furnace to handle gold bullion so the robbers let the Royal Mint do their work for them and waited until a shipment of coin was being made. They chose carefully,’ he said, watching the blank discs being cut out of the metal. ‘Had the train been carrying an issue of notes from the Bank of England, they would have ignored them because they might be traced by their serial numbers. Gold sovereigns are more easily disposed of, Mr Omber.’
‘That is certainly true.’
‘Then how did they know that you were only sending gold coin yesterday?’ wondered Leeming. ‘I have an uncomfortable feeling that someone found a way to get past all these steel doors of yours.’
The journey to Wolverhampton obliged Colbeck to travel second class on the Birmingham, Lancaster and Carlisle Railway. It took him through the heart of the Black Country and he looked out with dismay at the forges, mills, foundries, nail factories, coal mines and ironstone pits that stretched for miles beneath the curling dark smoke that spewed from a thousand brick chimneys. Cutting through the smoke, filling the sky with a fierce glare, were lurid flames from countless burning heaps of rubbish. Those who laboured for long hours in heavy industry were unacquainted with the light of day and vulnerable to hideous accidents or cruel diseases. Above the thunder of his train, Colbeck could hear the pounding of hammers and the booming explosion of a blast furnace.
Wolverhampton was a large, dirty, sprawling industrial town that was celebrated for the manufacture of locks, brass, tin, japanned wares, tools and nails. The immaculate detective looked rather incongruous in its workaday atmosphere. Given directions by the stationmaster, he elected to walk to his destination so that he could take a closer look at the people and place. By the time that he arrived at the Chubb Factory, he felt that he had the measure of Wolverhampton.
Silas Harcutt, the manager at the factory, could not understand why someone had come all the way from London to question him. He was a slim individual of middle height with the look of a man who had worked his way up to his position with a slowness that had left a residual resentment. Harcutt was abrupt.
‘Your visit is pointless, Inspector,’ he declared.
‘Not at all,’ said Colbeck. ‘I’ve always been curious to see the inside of the Chubb factory. I once had the privilege of a visit to the Bramah Works and it was a revelation.’
‘Bramah locks are nothing compared to ours.’
‘Your competitors would disagree. At the forthcoming Great Exhibition, they are to display a lock that is impossible to pick.’
‘We, too, will have our best lock on show,’ boasted Harcutt, ‘and we will challenge anyone to open it. I can tell you now that nobody will.’
‘You obviously have faith in your product.’
‘The Chubb name is a guarantee of quality.’
‘Nobody disputes that, Mr Harcutt,’ said Colbeck, ignoring the man’s brusque manner. ‘For professional reasons, I try to keep abreast of developments in the locksmith’s trade and I’m always interested to read about your progress. The railway safe that you devised was a marvel of its kind. Even so,’ he went on, ‘I fear that it was not able to prevent a consignment of money from being stolen.’
‘The locks were not picked,’ insisted the manager, huffily. ‘The safe is specifically designed so that a burglar has nothing to work upon but the keyholes with their protective internal barrels and the steel curtain at their mouths. Do not dare to blame us, Inspector. We were not at fault.’
‘I hope that turns out to be the case, sir.’
‘It is the case, Inspector. Let me show you why.’
Opening the door of his office, he led Colbeck down a corridor to a room that housed dozens of safes and locks. Harcutt walked across to a replica of the safe that the detective had seen on board the train.
‘You see?’ said the manager, patting the safe. ‘Far too heavy to lift without the aid of a crane and resistant to any amount of gunpowder. It is solid and commodious, able to carry a quarter of a ton of gold, coin, or a mixture of both.’
‘The robbers showed due respect for the Chubb name,’ said Colbeck. ‘Instead of trying to pick the locks, they opened them with the keys and the combination number. I am certain that they got neither from Spurling’s Bank and security at the Royal Mint is very tight.’
Harcutt was offended. ‘Are you suggesting that the keys came from here?’ he said, drawing himself up to his full height. ‘I regard that as an insult, Inspector.’
‘It was not meant to be. If I may examine the keys to this safe, I can tell you at once whether there has been subterfuge in your factory.’
‘That is inconceivable.’
‘I must press you on this point,’ said Colbeck, meaningfully.
Lips pursed, Harcutt turned away and strode back to his office with the detective at his heels. He had to use two keys and a combination number to open the wall safe, making sure that he kept his back to his visitor so that Colbeck could see nothing of the operation. Extracting a metal box, the manager unlocked it with a third key and handed it over.
Colbeck took out the keys. Unable to detect anything suspicious with the naked eye, he brought his magnifying glass out again. He saw exactly what he had expected to find.
‘Minute traces of wax,’ he noted, offering the glass to the other man. ‘Would you care to confirm that, Mr Harcutt?’
The manager took the magnifying glass and peered through it with disbelief. Both keys had discernible specks of wax still attached to them.
‘Who else was authorised to open your safe?’ asked Colbeck.
‘Only two people. Mr Dunworth, my deputy, is one of them.’
‘And the other?’
‘Daniel Slender.’
‘I need to speak to both of them at once, Mr Harcutt.’
‘Of course,’ said the manager, grudgingly. ‘Mr Dunworth is in the next office. But you’ll have to wait until you get back to London before you question Mr Slender.’
‘Oh?’
‘He left some weeks ago to take up a new post there.’ He saw the suspicion in Colbeck’s eyes. ‘You are quite wrong, Inspector,’ he continued, shaking his head. ‘Daniel Slender could not possibly be the culprit. He has been with us for decades. For the last few years, he has been looking after his sick mother in Willenhall. When she died, he felt that it was time to move out of the Midlands.’ He thrust the magnifying glass at Colbeck. ‘I have complete trust in Daniel Slender.’
The frock coat fitted perfectly. He preened himself in front of the mirror for minutes. Daniel Slender had finally fulfilled his ambition to wear clothing that had been tailored for him in Bond Street. Tall and well-proportioned, he looked as if he belonged in such fine apparel. When he had changed back into his other suit, he took a wad of five pounds notes from his wallet and began to peel them off. Years of self-denial were behind him now. He had enough money to change his appearance, his place in society and his whole life. He was content.
CHAPTER SIX
It was early evening before Robert Colbeck finally got back to his office in Scotland Yard. Victor Leeming was waiting to tell him about his visit to the Royal Mint and to voice his suspicion that someone there might have warned the train robbers
when gold coin was actually being dispatched to Birmingham. He took a positive delight in describing the processes by which gold bullion was transformed into coinage.
‘I have never seen such a large amount of money,’ he said.
‘No, Victor,’ remarked Colbeck. ‘The irony is that the men who sweat and strain to make the money probably get little of it in their wages. It is a cruel paradox. Workers who are surrounded by gold every day remain relatively poor. It must be a vexing occupation.’
‘A dangerous one as well, sir. Had I stayed in the refining shop any longer, the heat from those furnaces would have given me blisters. As it is, I can still smell those terrible fumes.’
‘I had my own share of fumes in the Midlands.’
‘Was the visit a useful one?’ asked Leeming.
‘Extremely useful. While you were learning about the mysteries of the Royal Mint, I was being taught sensible banking practices and given an insight into the art of the locksmith.’
Colbeck related the events of his day and explained why he had enjoyed travelling by rail so much. Leeming was not convinced that train rides of well over a hundred miles each way were anything but purgatory. He was happy to have missed the ordeal.
‘We now know where the keys were obtained,’ he said.
‘And the combination number, Victor. That, too, was essential.’
‘This man, Daniel Slender, must be responsible.’
‘Not according to the manager,’ said Colbeck, remembering the protestations of Silas Harcutt. ‘He claims that the fellow is innocent even though he is the only possible suspect. He set great store by the fact that Slender was a dutiful son who looked after an ailing mother.’
‘That certainly shows kindness on his part.’
