As a general rule, I enjoy researching all of my novels. Murder, mayhem, investigative procedures, it's all good stuff. This time around, however, I had a particularly wonderful experience, and for that I'm deeply indebted to the Rhode Island State Police. Not only are they one of the best law enforcement agencies in the country, but they are also helpful, generous and patient people. From explaining the proper protocol for rendering a salute to demonstrating the new AFIS technology, the officers went out of their way to answer my questions and impress upon me the pride they have in their organization. It worked. I'm very impressed by the RI State Police, and I have even started following the speed limit. Well, okay, so the latter half only lasted for a bit. I tried and that says something about their powers of persuasion right there.

Of course, as with all novels, I promptly warped most of the information they graciously provided. In this novel you'll find police procedure and forensics testing happening at approximately the speed of light. Also, my police detectives are perhaps a tad rougher around the edges and a bit more familiar with murder suspects than their real-life counterparts. Remember, the RI State Police detectives have real jobs. I, on the other hand, am a fiction writer who makes things up.

I would like to thank the following members of the RI State Police for their assistance: former Superintendent Colonel Edmond S. Culhane, Jr. (ret.); Superintendent Colonel Steven M. Pare; Major Michael Quinn; Inspector John J. Leyden, Jr.; Lieutenant John Virgilio; Lieutenant Mark Bilodeau; Corporal Eric L. Croce; and Detective James Dougherty.

From the Providence Police Department I would like to thank Lieutenant Paul Kennedy and Sergeant Napoleon Brito. They also gave me the warmest reception, as well as a wonderful collection of gory anecdotes. Let's just say I never fully appreciated the history of dismemberment in the Ocean State before visiting the PPD.

Finally, I owe the following people my deepest gratitude for assisting me in the development of this novel:

Dr. Gregory K. Moffatt, Ph.D., Professor of Psychology, Atlanta Christian College, a wonderful friend and a very wise man.

Albert A. Bucci, Assistant to the Director, State of Rhode Island Department of Corrections, who provided a highly enthusiastic overview of prison life.

Margaret Charpentier, pharmacist and general shoulder to cry on, as well as her fellow pharmacist/partner in crime, Kate Strong.

Monique Lemoine, speech language pathologist and very kind soul.

Kathy Hammond, phlebotomist, Rhode Island Blood Center, and my bloodsucker of choice.

Jim Martin, Public Information Officer, Department of the Attorney General, Rhode Island.

The Providence Preservation Society.

Kathleen Walsh, executive assistant and overall savior of my sanity.

And finally, my very tolerant husband, Anthony. This time around, it was his Ghirardelli double-chocolate brownies that saved the day.

Once again, all mistakes in the novel are mine. Anything you think is particularly brilliant I'll take responsibility for as well.

Happy reading!

IT STARTED AS A CONVERSATION:

“The scientists are the problem-not the cops. Cops are just cops. Some got a nose for jelly doughnuts; others got a nose for pensions. The scientists, though… I read about this case where they nailed a guy by matching the inside seam of his blue jeans with a bloody print left at the murder scene. I'm not kidding. Some expert testified that the wear pattern of denim is so individual there's something like a one-in-a-billion chance that another pair of jeans would leave the same print, yada, yada, yada. Fuckin' unreal.”

“Don't wear blue jeans,” the second man said.

The first man, a kid really, rolled his eyes. “That's fuckin' brilliant.”

The second man shrugged. “Before you lecture me about Calvin's sending someone to the big house, perhaps we should start with the basics. Fingerprints.”

“Gloves,” the kid said immediately.

“Gloves?” The man frowned. “And here I expected something much more innovative coming from you.”

“Hey, gloves are a pain in the ass, but then again, so is serving time. What else are you gonna do?”

“I don't know. But I don't want to wear gloves if I don't have to. Let's think about it.”

“You could wipe down everything,” the kid said shortly. “Ammonia dissolves fingerprint oil, you know. You could prepare a solution, ammonia and water. Afterwards, you could spray it on, wipe stuff down. You know, including…” The kid's voice trailed off. He didn't seem quite able to say the word, which the man thought was pretty funny, given everything this “kid” had done.

The man nodded. “Yes. Including. With ammonia, of course. Otherwise they might be able to print the woman's skin using Alternate Light Source or fumigation. Instead of spritzing, the other option is to put the woman in a tub. To ensure that you're being thorough.”

“Yeah.” The kid nodded his head, contemplating. “Still might miss a spot. And it involves a lot of maneuvering. Remember what the textbook said: ‘The more contact with the victim, the more evidence left behind.' ”

“True. Other ideas?”

“You could leave fake prints. I once met this guy from New York. His gang liked to cut off the hands of their rivals, and use them to leave false prints at their own crime scenes.”

“Did it work?”

“Well, half the gang was in Rikers at the time…”

“So it didn't work.”

“Probably not.”

The man pursed his lips. “It's an interesting thought, though. Creative. The police hate creativity. We should find out where those people went wrong.”

“I'll ask around.”

“A fingerprint is nothing but a ridge pattern,” the man thought out loud. “Fill in the valleys between the ridges and there's no more print. Seems like there's gotta be a way of doing that. Maybe smearing the fingertips with superglue? I've heard of it, but I don't know if it works.”

“Wouldn't that interfere with feel, though? I mean, if you're going to lose sensation, you might as well return to gloves which you know will do the trick.”

“There's scarring. Repeated cutting of the fingertips with a razor to obscure the print.”

“No thank you!”

“No pain, no gain,” the man said mildly.

“Yeah, and no pleasure, no point. What do you think scar tissue is gonna do to the nerve endings of your fingertips? Might as well hack 'em off and be done with it. Keep it simple, remember? Another thing the textbook pointed out-simple is good.”

The man shrugged. “Fine, then it's gloves. Thinnest latex possible. That resolves the matter of fingerprints. Next issue: DNA.”

“Shit,” the kid said.

“DNA is the kicker,” the man agreed. “With fingerprints you can watch what you touch. But with DNA… Now you have to consider your hair, your blood, your semen, your spit. Oh, and bite marks. Let's not forget about the power of dental matches.”

“Jesus, you are a sick son of a bitch.” The kid rolled his eyes again. “Look, don't bite anything or anyone. It's too risky. They've nailed thieves by matching their teeth to indentations left in a hunk of cheddar in the fridge. After that, God knows what they can do with a human breast.”

“Fair enough. Now back to DNA.”

“Pull an O.J.,” the kid said grumpily. “Let the lawyers deal with it.”
