“What do you need to move for a prosecution?” Mike Wilson asked as they took a look at the cast-iron stairs.
“Basically, a lack of any other suspects. I expect the prosecution service will accept she changed the air-conditioning. She is a medical student, after all.”
“So you'll interview his friends to see if anyone threatened him?”
“Friends, his agency, people he worked with. The usual. I'd love to try and track down his supplier, as well. But that would really cost you—they don't exactly rush out of the woodwork at times like these.”
He gave a small grin. “I know.”
“Previous case?”
“Crescent insures a lot of celebrity types. Having dealt with them before, I can see why we set the premiums so high.”
“Really?” Amanda was wondering if he was going to let any gossip loose when her cybofax bleeped. Denzil's face appeared on the screen with an indecently malicious expression. “What?” she asked cautiously.
“The saliva is Claire's. The skin under the fingertips is not.”
“Oh bugger,” she groaned. Even so, some part of her was glad Claire had possibly been cleared. Although she was still convinced the girl was hiding something. “Run a match through the central criminal records at the Home Office.” She didn't even consult Mike Wilson with that one.
“Already running,” Denzil said. “Plot getting thicker, huh?”
“Yeah, right.” She ended the call.
Wilson was looking up at the top of the stairs. “So what do you think? Skin scrape from whoever pushed him.”
“Looks that way. One last desperate grasp as he started to fall.” She walked over to the red outline of the body on the terra-cotta tiles, and turned a full circle. “So what else have we got? No sign yet of a forced entry, which implies either the security 'ware let them through or it was a professional hit and they could burn through the system without a trace.”
“Pushing someone off the top of the stairs isn't a widely used assassination method. It's heat-of-the-moment. Which fits.”
“Fits what?”
“Someone turned up just after Claire left. A friend, or someone he knew. He let them in. There was an argument. It would also explain the air-conditioning. If it was a professional hit, then whoever did that wouldn't need to confuse the time of death, it wouldn't matter to them. For some reason, our murderer still cares about messing with the time.”
“Still doesn't fit. If it was a friend, then the security 'ware would have an admissions record. There was nobody.”
“We'd better have it checked very thoroughly, then. Get into the base management program and see if there's any sign of tampering.”
Amanda nodded. “You have somebody who can do that?”
“Oh yes.”
“While they're at it, make sure they enhance the surveillance picture of the Ingalo when it left, I'd like to confirm no one was inside along with Claire.”
“Fair enough. What else do you need?”
She gestured out of the window wall. “Unless it was a real professional who yomped in over the fields, the only way to get here is to drive through the village. And believe me, that's not so easy. Bisbrooke is small, and confusing. The villagers would know all about strange cars. I want a door-to-door enquiry asking if any of them saw anything that night, any cars they didn't recognize, as well as full interviews with the neighboring apartments.”
“That's a lot of labor-intensive groundwork. Could we just wait and see if the DNA register comes up with anything first?”
“Okay. We need the other angle anyway. This will give us some time.”
“Other angle?”
“The motive, Mike. Personal, or financial, or professional jealousy, what-ever…We need to start the good old-fashioned process of elimination. So, you get your expert here to examine the security 'ware, and I'll get back to the station and give Alison a hand with Tyler's finances.”
It was late afternoon when Alison slapped a hand down on her terminal keyboard with a disgusted sigh, canceling a search program. “He doesn't have bloody finances, you've got to have money for that. All Tyler has are debts.”
Which wasn't strictly true. Amanda glanced at Tyler's bank statement again. To think, she always worried about her monthly salary payment arriving in time to satisfy her standing orders and credit-card bill. Some people obviously operated on a higher plane. Although he owed close to quarter of a million New Sterling, the banks just kept extending his credit limit. Why he didn't pay it off she couldn't understand. His cashflow was more than adequate. Of course, neither she nor Alison could track down where half of the money actually came from, and in most cases where it went. One account at a bank in Peterborough was used just for withdrawing large sums of hard cash.
Amanda looked over at Mike Wilson who was studying some of the details himself. “I think we might justifiably request a qualified accountant at this point.”
He ran a hand back through his hair, looking at a twisting column of numbers in one of the cubes with a perplexed expression. “I think you might be right.”
Denzil came in and grinned at the blatant despondency in the room. “Having fun?”
“Always,” Alison said sweetly.
“I have a positive result.”
Amanda sat up fast. “What?”
“The skin scrape is definitely nobody we know of. No record of that DNA in the Home Office memory core. I even squirted the problem over to Interpol. They don't have it either. And before you ask, neither does the FBI.” He gave Wilson an affable smile. “You'll get the bill tomorrow.”
“I live for it.”
“You want me to look elsewhere? Most countries will cooperate.”
“I think we'll have to,” Amanda said. “After all, that DNA is our murderer. Mike?”
“I agree. Although, I'd like to suggest widening the search parameters.”
“How?”
“Organizations such as Interpol and the FBI simply store the DNA of known criminals. If it were a professional hit, I'd say search every police memory core on the planet. However, we favor the theory that this was a heat-of-the-moment killing, do we not?”
“I can go with that,” she said.
“Then our murderer is unlikely to be listed.”
“It was always a long shot, but what else can we do?” She pointed at the cubes full of financial datawork. “If we can find a motive, we can track the murderer that way.”
“Crescent has a DNA-characteristics assembly program. I suggest we use that.”
Denzil whistled quietly. “I'm impressed.”
“I might be,” Amanda said. “If I knew what you were talking about.”
“The genes which make us what we are, are spaced out along the genome, the map of our DNA,” Mike Wilson said. “Now that we know which site designates which protein or characteristic, like hair color or shape of the ear, it's possible to examine the genes which contribute to the facial features and see what that face will look like.”
“You mean you can give me a picture of this person?” Amanda asked.
“Essentially, yes. We can then ask Tyler's friends and acquaintances if they recognize him…or her.” He waved a hand at the busy terminal cubes. “Got to be easier than this, quicker, too. Crescent can also run standard comparison programs with the visual images stored in our data cores, and with the security departments of all the other companies we have reciprocal arrangements with. I think you'll find they're considerably more extensive than the criminal records held by governments. For a start, between us, the insurance companies have copies of every driving license issued in Europe. And we already decided the murderer drove to Bisbrooke.”
