Chapter 47
“I know smoking is bad, ma’am,” he said. “I quit for a long time, but with all this explosion tragedy, I started up again.”
“Do you know that none of the three medical examiners, Webber, Pilgrim, or Rankin, smoke?” said Diane. “You know why?”
He shook his head.
“Because they’ve all seen firsthand what smokers’ lungs look like,” said Diane.
“Well, I’ll probably quit again. Right now I need to take a statement,” he said.
Diane gave him a brief version of what happened to her, not going into treasure hunts, dolls, secret codes, or historic hurricanes. She’d tell Garnett, but she didn’t really want to go into the whole thing right now-especially while her mind was focused on something else.
“Did he take anything?” asked the policeman.
“I haven’t been back to my office to check my safe. I’ll notify the police if anything’s missing. Why do you carry your cigarette behind your ear?” she said, trying to bring the conversation back to the Doral held in place between his ear and his brain. He looked under twenty-six. So much for David’s statistics.
“Cause it’ll get crushed in my pocket, ma’am. I’ve been trying not to start back, so I bum cigarettes instead of buying them. That way, I have only one at a time.” He took the cigarette between his fingers and looked at it. “Actually, I prefer a Marlboro, but beggars can’t be choosers.”
“Who did you bum that from?” asked Diane.
“Archie Donahue,” he said.
So, perhaps David’s statistics were right after all.
“Well, I wish you luck in your efforts to stop smoking,” she said.
“Thank you, ma’am.”
He folded his pad of paper and put it in his pocket with his pen. He stuck his cigarette back behind his ear and left.
Diane finished her breakfast, pondering what she’d learned. Which was what? Archie smoked Dorals? Not much. Hardly anything. There were probably others in the department who smoked them. Certainly not an indictment. She closed her eyes to think.
What did the person who attacked Jin hit him with-butt of his gun, nightstick, rock? I should have stayed up on the ridge to look for blunt instruments. Instead, I left the policemen there to look while I took Jin to the doctor. Ample chance to move the weapon to a new location. Damn. But if the weapon was something he carries, he may have only wiped the blood off. We could still find blood and bits of Jin’s flesh. But everybody knows about blood nowadays, especially policemen. He’d have cleaned it with kerosene or bleach. We might at least be able to detect that. And that would still leave us nowhere.
“I need to get out of here,” she said out loud.
“Not until the doctor says you can go.”
She opened her eyes and looked at Frank. She had forgotten to call him. Damn. He pulled up a chair and sat down.
“Why aren’t you at work?” she said.
“I had business in Rosewood today. It doesn’t happen often that there’s a Rosewood connection with a case I’m working on, but when it does happen, I take advantage of it. Why didn’t you call me?”
“I meant to, but I got conked on the head and forgot-really,” she said.
“David told me what happened this morning when I called the crime lab,” he said. “I’ll take you home. When are you being released?”
“As soon as I see the doctor,” said Diane.
Just as she said it, the doctor entered her room.
“Your CT scan was fine. You can go home. Get plenty of rest and sleep. We’ll give you a list of symptoms to watch for. If any of them occurs, call or come back here immediately.”
“Thanks. I’m ready to get out of here,” said Diane.
He smiled, handed her a prescription for pain pills, and went off to see other patients.
Diane got dressed and was still waiting thirty minutes later for someone to come and get her, tell her she could go, or… something.
“Be patient,” said Frank.
“I really don’t like hospitals,” said Diane. “And I don’t like waiting. I think I’ll start charging for my waiting time. Maybe it’ll get my bill down to some reasonable amount.”
“Isn’t irritability one of the signs you’re supposed to watch out for?” said Frank.
She was about to retort when the nurse came with the paperwork and a wheelchair. Diane signed the paperwork.
“I don’t need the wheelchair,” she said.
“Everyone leaves in a wheelchair. It’s hospital policy,” said the nurse.
“It’s not mine,” said Diane and walked out ahead of Frank and the nurse.
Frank caught up with her. “Diane, don’t you think you’d better slow down? What’s up with you?”
“I just want out of here. Do you know how much time I’ve spent in the hospital-either visiting people I care about or being a patient myself?”
“Yes, but something besides your concussion has you irritated,” he said.
“Right now, one of the suspects I have in mind for the killings of McNair and Stanton is someone I like. And I absolutely hate that. My gut reaction is to just let him go, and I don’t like that feeling, either. I’m at odds with myself and it’s damned uncomfortable. Plus, it pisses me off when a fish steals my bait.”
After Diane had insisted on being taken to the museum instead of home, Frank insisted on an explanation of what happened to her. She fumbled through an account of her intention to use the code to catch the doll thief-and probably Joana Cipriano’s murderer.
“Tell me again, how was this plan supposed to work?” asked Frank as he drove toward the museum.
“I told you, I hadn’t thought it out enough to implement it. He struck too soon,” she said.
“You know, you come up with some of the worst plans,” said Frank. “Remember that one in your museum vault?”
“I wasn’t finished with this one-there was no plan being played out. They just came and attacked me. The result would have been the same had I not been thinking of a plan at all. As it is, they do have the wrong code.”
“You may have delayed them, but how does that get you closer to catching them?” asked Frank.
“It doesn’t,” said Diane. “I was going to use the forged code as bait to catch them. How many times do I have to go over this so that you understand it? There was nothing I did, no plan I put in motion that caused them to come after me. They did this on their own.”
Frank pulled into the museum parking lot and Diane got out. The first place she headed was to Security. Frank followed and started to open the door for her, but she beat him to it. Everyone stopped what they were doing when Diane walked in.
“Dr. Fallon.” The receptionist, a student in criminology from Bartram, smiled meekly. “It’s good to see you. I hope…” She hesitated and smiled, looking embarrassed. “I’ll get Napier. She’s in the video room reviewing recordings.” She left to get Chanell.
I must look a fright, thought Diane. Everyone looks scared.
Chanell came hurrying out of the video room.
“Dr. Fallon, I hardly know what to say. Please come into my office and I’ll fill you in on what we’ve found so far.”
“I’ll hang around out here,” said Frank.
Diane went in the office with Chanell and sat down.
“What have you found?” she asked.
“Like you suggested, we looked at the people who were in the building for classes. We cross-referenced the security recordings to the class rolls. We’ve found a couple of people to look at. However, Dr. Shane-she’s teaching the bird watching series-does not keep good records. We had her in here telling us who all of her students are. There are a couple of new ones she didn’t know.” She stopped and took a breath. “So far, that’s all we have.”
“Do you know how my attacker got in this section?” Diane asked.
“We’re thinking he or she-it could have been a woman-got in during museum hours. There was a period of time wh
en some of the docents and exhibit specialists were away from their usual stations visiting Public Relations. We think he or she stayed-maybe in the bathroom or a storage closet-until closing. No one is on the video slipping in or breaking in the front or back entrance of this wing.”
Diane rose. “Let me know when you have more.”
“Yes, ma’am,” said Chanell.
Diane left and headed for the crime lab.
“You don’t have to babysit me,” she told Frank.
“Tired of my company already?” he said.
“I don’t want to keep you from your appointment,” she said.
“I’ve already had my appointment-early this morning. I’m all yours all day to watch your six.”
They rode the elevator to the third floor and crossed over to the west wing. Darth Vader was still on guard.
“I probably need to put him at the front entrance,” said Diane as she crossed over the rope and went toward the door to the crime lab.
“You think you need to slow down a bit?” said Frank.
“Why?” said Diane.
“Because you just got out of the hospital and you have a concussion?”
“I’m fine,” she said, keying in her code and entering the lab.
David looked up from his computer when she entered.
“You’re looking better than when I left you,” he said. “I just called the hospital and they told me you had been released. I figured you’d be back here.”
Diane sat down at the round table. David and Jin joined her while Neva was on the phone. Frank sat off to one side.
“Archie Donahue smokes Dorals,” Diane said. “Those are probably his you picked up at tent city. There is nothing to connect his Dorals with the ones you found on the ridge.”
“But…,” said David.
“But nothing… that’s it,” said Diane.
“That’s not all of it,” said Neva, joining them. “I was talking to someone at the station. Archie Donahue left right after he checked in this morning. No one knows where he went.”
“So it’s in the hands of the police,” said Diane. “Neva, call Garnett and tell him about the Dorals and leave it with him.”
Neva left and made the call to Garnett. It was quick. Diane heard Neva say they didn’t know what it meant; it was just information. None of them wanted the murderer to be a policeman, and if it was, they all had the uncomfortable feeling of not wanting him caught. Not a good philosophy for criminalists.
Neva sat back down at the table. “Garnett asked about you,” she said. “He said he’d drop by later today.”
Diane saw a paper rolled up in Jin’s hands.
“OK, Jin,” she said, “what do you have on the code?”
Chapter 48
Jin looked at the paper in his hand and turned red. Neva and David laughed.
“You don’t have anything, do you?” said Neva.
“It’s not a cryptogram,” said Jin. “It can’t be. I don’t think it’s anything.”
“May I see it?” asked Frank.
Jin handed him the paper, and Frank unrolled the page and examined the letters.
“This is the code that was in the doll you were telling me about?” asked Frank.
“Yes,” said Diane.
“Have you tried other decoding techniques? If it’s not a simple cryptogram, it might be another kind of cipher.”
“Do you think you can decode it?” said Diane.
“Don’t know till I try,” said Frank.
Jin looked more depressed than when the cigarette butts were stolen from him.
“Jin,” said Neva, “you can’t know everything. Don’t look so glum.”
“It’s just, I’m really good at codes,” he said. His entire face was turned down in a frown as he watched Frank studying the string of letters on the wrinkled paper.
“Do you know anything about the guy who wrote it?” asked Frank.
“A little,” said Diane. She related the story of Leo Parrish, the treasure train, and the Labor Day hurricane of 1935.
“So,” said Frank, “this whole thing may be a hoax.”
“That’s what I think,” said Jin. “It’s just a string of random letters.”
“Could be,” said Frank. “You know it’s not a cryptogram because the frequency of occurrence of the letters didn’t lend itself to an answer, right?”
“No,” said Jin. “Nor does looking at the two-and three-letter words or the endings or beginnings of words. Nothing makes sense.”
“Then we need to look at another type of encryption method. You say Leo did his thing in the 1930s?”
“Yes,” said Diane.
“OK, so it’s not modern. No computer to help him with it. Maybe it’s something popular among coders of his time, like Vigenere’s method,” said Frank. “Where, for example, the cipher letter for e in one word isn’t necessarily the same cipher letter for an e in another word.”
“Well, you’ve completely lost me,” said Neva.
“Wow,” said Jin, leaning forward, his eyes now sparkling with interest. “No wonder I couldn’t decipher it. How do you know about this stuff, Frank?”
“It’s only what he does for a living,” said David.
“No kidding. I didn’t know that’s what you do,” said Jin.
“It’s part of what I do,” said Frank. “A lot of cybercrime involves hiding things by use of encryption.”
“Can you decipher it?” Diane asked.
“Probably. It will be easier if I have the keyword,” he said.
“Keyword?” they all said in unison.
“Several of the early ciphers required a keyword. Even without the keyword, there are other ways it can be deciphered and a good computer program can work it out, but if I have the keyword, I can do it fairly quickly. Are there any possible keywords from this story of yours?”
“How about a key sentence?” said Diane. “The making of palimpsests was possible even with papyri.”
Frank raised his eyebrows and she explained about the amazing coincidence of hearing that phrase in the library, Juliet’s fear of the word palimpsest and her dramatic reaction to hearing the complete sentence.
“Well that’s certainly odd,” said Frank.
David, Neva, and Jin stared at her with their mouths open.
“Wow,” said Jin again. “We hadn’t heard that story, Boss.”
“There’s been so much going on lately,” Diane said. She turned back to Frank. “Do you think palimpsest could be the keyword?”
“Could be. I’ll give it a try. Can I use a computer?” said Frank. “You do have word processing programs on your computers, don’t you?”
“Of course,” said David.
He led Frank to his computer and called up Word-Perfect. Frank sat down and started typing.
David moved an empty chair next to Frank, and Diane sat down. She was feeling a little weak, and her headache was back, but she didn’t want to mention it. David probably guessed, she thought. Frank reached over and squeezed her hand. He probably senses my weakness too, damn it.
Frank made a grid twenty-seven by twenty-six. On the top row he keyed in each letter of the alphabet in lowercase. Under the a in the first column, he repeated the alphabet starting with an uppercase B and putting the uppercase A on the bottom of the column after Z. He did the same thing in the next column-under the lowercase b he put an uppercase C and put the uppercase A and B at the bottom of the column after Z. Each successive uppercase alphabet was shifted one letter with respect to the previous column.
“This is called a Vigenere square,” said Frank when he finished. “The lowercase letters across the top represent the plain text. The uppercase letters in the columns represent the cipher text.”
Neva made a gesture with her hand going over her head. “This looks too much like math with letters,” said Neva.
“Not far from wrong,” said Frank.
“This is great,” said Jin. “Where have I been that I didn’t
know this?”
“I don’t know,” said Frank grinning. “This is Secret Code 101.”
“How does it work?” said Diane.
“Let’s say the keyword is DIANE. In the left column I will use only those letters.” He used the word processing program to highlight the letters of DIANE and continued the shading all across the row in the table for each letter.
“Now, suppose we have the message, ‘The house that Jack built.’ So, we have to make another table…,” began Frank.
“OK,” said Neva. “You mentioned something about a computer program that would do this?”
“Yes, but I don’t have it,” said Frank. “Let’s have a little patience. Think of this as fun. Jin does.”
“You betcha,” said Jin. He pulled up a chair and leaned forward, staring at the screen. “You said you use a second table?”
“Yes,” said Frank. “If the keyword is DIANE, on the header row of this table I write the word DIANE over and over again until I have used up all the letters in the message to be encoded.
“Oh, I get it.” Jin jumped up and sat down again. “That’s brilliant. No wonder I couldn’t make heads or tails of it.”
“Explain it to those of us who don’t get it,” said Neva.
“To encrypt ‘The house that Jack built,’ ” said Frank, “I go to the new table and see that the first letter in the message is t and it is under the letter D in the keyword DIANE. I go to the Vigenere square and use it like the coordinates of a map to find the encryption letter I need. Go to D on the left most column and find where it intersects with t in the top row. The letter where the column and row intersect is W. Do the same thing for the second letter. The h is under I in the keyword Diane. Go to the square and we find that I and h intersect at P. Keep going and you can encrypt the whole sentence. You do the reverse process to decode the message.”
“That is so cool,” said Jin. “You’ll have to show me how to decode it the other ways you were talking about.”
“Sure. It’s more time-consuming. As you see, if you have the keyword, it’s a piece of cake.”
“Yeah,” said David, “I’d like to see the computer program. That would be an interesting algorithm.”
