He'd never revived a cold case in quite this way.

Detective Quentin Altman rocked back, his chair squealing I with the telltale caw of ageing government furniture, and I eyed the narrow, jittery man sitting across from him. "Go on," the cop said.

"So I check out this book from the library. Just for the fun of it. I never do that, just read a book for the fun of it. I mean, never. I don't get much time off, you know."

Altman hadn't known this, but he could certainly have deduced it. Gordon Wallace was the Greenville Tribune's sole crime reporter and must've spent sixty, seventy hours a week banging out copy, to judge by the number of stories appearing under his byline every day.

"And I'm reading along and-" "What is it you're reading?"

"A murder mystery. I'll get to that… I'm reading along and I'm irritated," the reporter continued, "because somebody'd circled some passages. In a library book."

Altman grunted distractedly. He was head of Homicide in a burg with a small-town name but big-city crime statistics. The fifty-something detective was busy and he didn't have much time for reporters with crackpot theories. There were twenty-two folders of current cases on his desk and here Wallace was delivering some elliptical message about defaced books.

"I don't pay much attention at first, but I go back and reread one of the circled paragraphs. It jogs my memory. Anyway, I checked the morgue-"

"Morgue?" Altman frowned, rubbing his wiry red hair, which showed not a strand of gray.

"Our morgue, not yours. In the newspaper office. All the old stories."

"Got it. How 'bout getting to the point?"

"I found the articles about the Kimberly Banning murder."

Altman grew more attentive. Twenty-eight-year-old Kimberly had been strangled to death a year ago. The murder occurred two weeks after a similar killing-of a young female grad student. The two deaths appeared to be the work of the same person, but there were few forensic leads and no motive that anyone could determine. The cases prompted a task-force investigation but eventually the suspects dried up and blew away like maple leaves in October, and soon the case grew cold.

Tall and gaunt, with tendons and veins rising from his pale skin, Wallace tried to tone down his intimidating physique and face with brown tweed jackets, corduroy slacks, and pastel shirts, an attempt that was, as today, completely unsuccessful. He asked the cop, 'Tfouremember how the whole town was paranoid after the first girl was killed? And how everybody was double-locking their doors and never letting strangers into their houses?"

Altman nodded.

"Well, look at this." The reporter pulled latex gloves out of his pocket and put them on.

"Why the gloves, Wallace?"

The man ignored the question and dug a book out of his battered briefcase. Altman got a look at the title. Two Deaths in a Small Town. He'd never heard of it.

"This was published six months before the first killing." He opened the book to a yellow Post-It tab and pushed it forward. "Read those paragraphs." The detective pulled on his CVS drugstore glasses and leaned forward.

The hunter knew that now that he'd killed once, the town would be more alert than ever. Its soul would beedgier, its collective nerves would be as tense as an animal trap's blue-steel spring. Women would notstroll the streets alone, and those who did would be looking around themselves constantly, alert for any risk. Only a fool would let a stranger into her house and the hunter did not enjoy killing fools.

So on Tuesday night he waited until nearly bedtime-eleven P.M.-and then slipped onto Maple Street. There, he doused a parked convertible's roof with gasoline and ignited the pungent, amber liquid. A huge whoosh… He hid in the bushes and, hypnotized by the tornado of flames and ebony smoke swirling into the night sky above the dying car, he waited. In ten minutes behemoths of fire trucks roared up the street, their wailing sirens drawing people from their homes to find out what the excitement might be.

Among those on the sidewalk was a young, demure blonde with a heart-shaped face, Clara Steading. This was the woman the hunter knew he had to possess-possess completely. She was love incarnate, amore herself, she was beauty, she was passion… and she was also completely ignorant of her role as the object of his demented desire. Clara shivered in her bathrobe, standing on the sidewalk along with a clutch of chattering neighbors as they watched the firemen extinguish the blaze and offered words of sympathy to the dismayed owner of the car, who lived a few doors away.

Finally the onlookers grew bored, or repulsed by the bitter smell of the burnt rubber and plastic, and they returned to their beds or their late-night snacks or their mind-numbing TV. But their vigilance didn't flag; the moment they stepped inside, every one of them locked their doors and windows carefully-to make certain that the strangler would not wreak his carnage in their homes.

Though in Clara Steading's case, her diligence in securing the deadbolt and chains had a somewhat different effect: locking the hunter inside with her.

"Jesus," Altman muttered. "That's just what happened in the Banning case, how the perp got inside. He set fire to a car."

"A convertible," Wallace added. "And then I went back and found another passage that'd been circled. When I'd read it at first I didn't pay any attention. But you know what it said? It was how the killer had stalked the first victim by pretending to work for the city and trimming the plants in a park across from her apartment."

This was just how the first victim of the Greenville Strangler, the pretty grad student, had been stalked. "So the killer's a copycat," Altman murmured. "He used the novel for research."

Which meant that there could be evidence in the book that might lead to the perp: fingerprints, ink, handwriting.

Altman stared at the brooding cover-a drawing of a man's silhouette peering into the window of a house. The detective pulled on his own pair of latex gloves and slipped the book into an evidence envelope. He nodded at the reporter and said a heartfelt, "Thanks. We haven't had a lead on this one in over eight months."

Walking into the office next to his-that of his assistant, a young crew-cut detective named Josh Randall-he instructed the man to take the book to the county lab for analysis. When he returned, Wallace was still sitting expectantly in the hard chair across from Altman's desk.

Altman wasn't surprised he hadn't left. "And the quid pro quo?" the detective asked. "For your good deed?"

"I want an exclusive. What else?"

"I figured."

Altman didn't mind this in theory; cold cases were bad for the department's image and solving cold cases was good for a cop's career. Not to mention that there was still a killer out there. He'd never liked Wallace, though, who always seemed a little out of control in a spooky way and was as irritating as most crusaders usually are.

"Okay, you've got an exclusive," Altman said. "Illkeep you posted." He rose and shook the reporter's hand. Waited for him to leave.

"Oh, I'm not going anywhere, my friend."

"This'san official investigation-"

"And it wouldn't've been one without me. I want to write this one from the inside out. Tell my readers how a homicide investigation works from your point of view."

Altman argued some more, but in the end he gave in; he felt he had no choice. He said, "Just don't get in my way. If you get in the way, you're out of here."

"Wouldn't think of it." He frowned an eerie look into his long, toothy face. "I might even be helpful." Maybe it was a joke, but there was nothing humorous about the delivery. He then looked up expectantly at the detective. "So, whadda we do next?"
