   merit," he said. "There is a mouse in this hole!
   What move must the cat make now?"
   His decision took him to the nearest post office.
   Here he put through a couple of telephone calls.
   The result seemed to be satisfactory. He bent his
   steps to Charman's Green police station, where he
   inquired for Inspector Sims.
   Inspector Sims was a big, burly man with a
   hearty manner. "M. Poirot?" he inquired. "I
   thought so. I've just this minute had a telephone
   call through from the chief constable about you.
   He said you'd be dropping in. Come into my of-rice."
   The door shut, the inspector waved Poirot to
   one chair, settled himself in another, and turned a
   gaze of acute inquiry upon his visitor.
   "You're very quick onto the mark, M. Poirot.
   Come to see us about this Rosebank case almost
   before we know it is a case. What put you onto
   it?"
   Poirot drew out the letter he had received and
   handed it to the inspector. The latter read it with
   some interest.
   "Interesting," he said. "The trouble is, it might
   mean so many things. Pity she couldn't have been
   a little more explicit. It would have helped Us
   now."
   "Or there might have been no need for help."
   "You mean?"
   "She might have been alive."
   "You go as far as that, do you? H'm--I'm not
   sure you're wrong."
   "I pray of you, inspector, recount to me the
   facts. I know nothing at all."

   "That's easily done. Old lady was taken bad
   after dinner on Tuesday night. Very alarming.
   Convulsions--spasms--what not. They sent for
   the doctor. By the time he arrived she was dead.
   Idea was she'd died of a fit. Well, he didn't much
   like the look of things. He hemmed and hawed
   and put it with a bit of soft sawder, but he made it
   clear that he couldn't give a death certificate. And
   as far as the family go, that's where the matter
   stands. They're awaiting the result of the postmortem.
   We've got a bit farther. The doctor gave
   us the tip right away--he and the police surgeon
   did the autopsy together--and the result is in no
   doubt whatever. The old lady died of a large dose
   of strychnine."
   "Aha!"
   "That's right. Very nasty bit of work. Point is,
   who gave it to her? It must have been administered

   as bitter as gall. The doctor told me you could
   taste it in a solution of one in a thousand, or something
   like that."
   "Coffee?"
   "Coffee's more like it, but the old lady never
   took coffee."
   "I see your point. Yes, it seems an insuperable
   difficulty. What did she drink at the meal?"
   "Water."
   "Worse and worse."
   '!Bit of a teaser, isn't it?"
   "She had money, the old lady?"
   "Very well to do, I imagine. Of course, we
   haven't got exact details yet. The Delafontaines
   are pretty badly off, from what I can make out.
   The old lady helped with the upkeep of the
   house."
   Poirot smiled a little. He said, "So you suspect
   the Delafontaines. Which of them?"
   "I don't exactly say I suspect either of them in
   particular. But there it is; they're her only near
   relations, and her death brings them a tidy sum of
   money, I've no doubt. We all know what human
   nature is I"
   "Sometimes inhuman--yes, that is very true.
   And there was nothing else the old lady ate or
   drank?"
   "Well, as a matter of fact--"'
   "Ah, voild! I felt that you had something, as
   you say, up your sleeve--the soup, the fish pie, the
   apple tart--a btise! Now we come to the hub of
   the affair."
   "I don't know about that. But as a matter of
   fact, the old girl took a cachet before meals. You

   know, not a pill or a tablet; one of those rice-paper
   things with a powder inside. Some perfectly
   harmless thing for the digestion."
   "Admirable. Nothing is easier than to fill a
   cachet with strychnine and substitute it for one of
   the others. It slips down the throat with a drink of
   water and is not tasted."
   "That's all right. The trouble is, the girl gave it
   to her."
   "The Russian girl?"
   "Yes. Katrina Rieger. She was a kind of lady-help,
   nurse-companion to Miss Barrowby. Fairly
   ordered about by her, too, I gather. Fetch this,
   fetch that, fetch the other, rub my back, pour out
   my medicine, run round to the chemist--all that
   sort of business. You know how it is with these old
   women--they mean to be kind, but what they
   need is a sort of black slave!"
   Poirot smiled.
   "And there you are, you see," continued In-spector
   Sims. "It doesn't fit in what you might
   call nicely. Why should the girl poison her? Miss
   Barrowby dies and now the girl will be out of a
   job, and jobs aren't so easy to findshe's not
   trained or anything."
   "Still," suggested Poirot, "if the box of cachets
   was left about, anyone in the house might 
have the
   opportunity."
   "Naturally we're onto that, M. Poirot. I don't
   mind telling you we're making our inquiries--quiet
   like, if you understand me. When the pre-scription
   was last made up, where it was usually
   kept; patience and a lot of spade work--that's
   what will do the trick in the end. And then there's

   "Quite

   dream of murdering anyone."
   Poirot sighed. "How I miss my friend Hastings.
   He had such an imagination. Such a romantic
   mind! It is true that he always imagined wrong--but
   that in itself was a guide."
   Miss Lemon was silent. She had heard about
   Captain Hastings before, and Was not interested.
   She looked longingly at the typewritten sheet in
   front of her.
   "So it seems to you reasonable," mused Poirot.
   "Doesn't it to you?"
   "I am almost afraid it does," sighed Poirot.
   The telephone rang and Miss Lemon went out
   of the room to answer it. She came back to say,
   "It's Inspector Sims again."
   Poirot hurried to the instrument." 'Allo, 'allo.
   What is that you say?"
   Sims repeated his statement. "We've fotmd

   "Precisely. The fishmonger who supplied Rose-bank
   with fish. When you have found him you
   will ask him a certain question."
   He handed her a slip of paper. Miss Lemon
   took it, noted its contents without interest, then
   nodded and slipped the lid on her typewriter.
   "We will go to Charman's Green together,"
   said Poirot. "You to the fishmonger and I to the
   police station. It will take us but half an hour from
   Baker Street."
   On arrival at his destination, he was greeted by
   the surprised Inspector Sims. "Well, this is quick
   work, M. Poirot. I was talking to you on the
   phone only an hour ago."
   "I have a request to make to you; that you
   allow me to see this girl Katrina--what is her
   "Katrina Rieger. Well, I don't suppose there's
   any objection to that."
   The girl Katrina looked even more sallow and
   sullen than ever.
   Poirot spoke to her very gently. "Mademoi-selle,
   I want you to believe that I am not your
   enemy. I want you to tell me the truth."
   Her eyes snapped defiantly. "I have told the
   truth.' To everyone I have told the truth! If the old
   lady was poisoned, it was not I who poisoned her.
   It is all a mistake. You wish to prevent me having
   the money." Her voice was rasping. She looked,
   he thought, like a miserable little cornered rat.
   "Tell me about this cachet, mademoiselle," M.
   Poirot went on. "Did no one handle it but you?"
   "I have said so, have I not? They were made up
   at the chemist's that afternoon. I brought them
   74
   Agatha Christie
   back with me in my bag--that was just before
   supper. I opened the box and gave Miss Barrowby
   one with a glass of water."
   "No one touched them but you?"
   "No." A cornered rat--with courage!
   "And Miss Barrowby had for supper only what
   we have been told. The soup, the fish pie, the
   tart?"
   "Yes." A hopeless "yes"--dark, smoldering
   eyes that saw no light anywhere.
>   Poirot patted her shoulder. "Be of good cour-age,
   mademoiselle. There may yet be freedom--yes,
   and moneyma life of ease."
   She looked at him suspiciously.
   As he went out Sims said to him, "I didn't quite
   get what you said through the telephone--some-thing
   about the girl having a friend."
   "She has one. Me!" said Hercule Poirot, and
   had left the police station before the inspector
   could pull his wits together.
   At the Green Cat tearooms, Miss Lemon did
   not keep her employer waiting. She went straight
   to the point.
   "The man's name is Rudge, in the High Street,
   and you were quite right. A dozen and a half ex-actly.
   I've made a note of what he said." She
   handed it to him.
   "Arrr." It was a deep, rich sound like the purr
   of a cat.
   Hercule Poirot betook himself to Rosebank. As
   he stood in the front garden, the sun setting be-hind
   him, Mary Delafontaine came out to him.

   "M. Poirot?" Her voice sounded surprised.
   "You have come back?"
   "Yes, I have come back." He paused and then
   said, "When I first came here, madame, the
