That sensitivity was another strength. Worden was one of the few white detectives in homicide who could sit across the desk from a fifteen-year-old black kid and make it clear-with nothing more than a look and a word or two-that they were both beginning with a blank page. Respect brought respect, contempt the same. Anyone with eyes could see that the bargain being offered was a fair one.

It was Worden, for example, who won the gay community’s trust when a series of homosexual murders began plaguing the Mount Vernon neighborhood downtown. The department as a whole was still shunned by many in the gay community for a history of harassment, both real and perceived. But Worden could walk into any Park Avenue club, show a bartender a series of BPI photos and get some truthful answers. His word was his bond and it wasn’t his job to judge or threaten. He didn’t need anyone to come out of any closets or file any official report of crimes. He just needed to know: Is the guy in the photo the same one out hustling in the bars, the same one who’s been beating and robbing the men who pick him up? When the Mount Vernon murders went down, Worden made his point by taking his whole squad to a gay bar on Washington Boulevard, where he bought one round for the place and then, to the delight of the other detectives, drank free for the rest of the night.

Even in the homicide unit, where a measure of talent and intelligence was assumed, Worden was recognized as a precious commodity-a cop’s cop, a true investigator. For his three years in homicide, he had worked the midnight shifts and double shifts beside younger men. He showed them what twenty-five years can teach and, at the same time, he learned the new tricks that homicide work could teach him. Until Monroe Street, Worden seemed indestructible if not infallible. Until Monroe Street, it had seemed as if the man would go on handling calls forever.

John Scott, dead in an alley with a handful of Western men standing over his body, was, quite simply, the one that got away. Beyond the emotional cost of investigating other cops, of having them lie to you like any other shithead off the street, the Monroe Street probe had become for Worden what the Latonya Wallace murder was for Pellegrini. A man solves ten consecutive murders and begins to believe that he can stay out on the edge forever. Then comes the red ball, the one with a bad bounce, and the same man suddenly begins to wonder where it ends-all the case files, all the reports, all the wounds on all the dead men from all the scenes-so many crimes that the names and faces lose their meaning, until those deprived of liberty and those deprived of life blur into the same sad image.

That alone might be reason enough for Worden to quit, but there were others too. For one thing, he no longer had a family to support. His children were grown, and his wife was long accustomed to what had become a ten-year separation. They had reached an equilibrium: Worden had never filed for a divorce; his wife, he knew, would never file either. As far as his own finances were concerned, Worden was guaranteed a 60 percent pension as soon as he put in his retirement papers, so he was actually earning less than half of his paystub. On his days off, he made better money delivering furs to customers from summer storage, or he worked on the home he had bought down in Brooklyn Park. He was good with his hands and tools, and there was certainly money to be made in home improvements. No less a homicide fixture than Jay Landsman was making thousands of dollars from a company he operated in his spare time; the joke was that Landsman could solve your mother’s murder in a week-or four days if you also wanted to run a new deck off the back patio.

On the other side of the ledger were two good reasons to stay. First there was Diane, the red-headed secretary from the Special Investigations Section down the hall, who by bravely endeavoring to domesticate Worden had won the awe and sympathy of the entire homicide unit. The truth was that Worden was hooked; the gold “D &D” signature ring on his left hand said as much. But even if they got married tomorrow-and Worden was still coming to terms with the idea of something permanent-Diane would not be eligible for full benefits unless he stayed with the department for another year. As a forty-nine-year-old cop with hypertension, Worden had to think about that sort of thing.

Less practically, there was also the small, clear voice in the back of Worden’s head that told him he was meant for this job and no other, the voice that told him that he was still having a helluva time. In his heart of hearts, Worden wanted very much to keep hearing that voice.

A week ago, Waltemeyer had pulled a 1975 murder case out of the back files, a Highlandtown bar robbery in which the shooter had been charged in a warrant but never apprehended. Who would have believed that thirteen years could pass before the suspect finally surfaced in Salt Lake City, telling a friend about a crime he thought everyone had forgotten? Who would have believed that the case file would still contain a photograph of an identification lineup from 1975, a lineup in which five detectives stood shoulder-to-shoulder with one genuine suspect? And check out the face on that heavyset young man, the one with thick blond hair and deep blue eyes, the one staring at the camera, trying hard to look more felon than robbery detective? Donald Worden was thirty-six in that photograph-harder, thinner, gaudily dressed in the kind of checked pants and polyester sport coat that marked an up-and-coming Baltimore detective of an earlier epoch.

Waltemeyer, of course, paraded the photograph around the squad-room, as if he had unearthed the mummified remains of some ancient king. No, Worden told him, I don’t want it for a goddamn souvenir.

The only thing that saved him that day was a ringing phone line and a west side cutting. Worden, like any old fire dog, was out at the sound of the bell. He grabbed the index card with the address and time-of-dispatch and was halfway to the elevators before any other detective could even think about taking the call.

Appropriate to the moment, his partner on the call was Kincaid, another twenty-year man, and together they worked the scene on Franklin-town Road. It was a straight-up domestic stabbing, with the knife on the front lawn and a blood trail leading all the way back into the rowhouse. On the living room floor, immersed in a ten-foot-wide lake of purple-red blood, was the phone used by the husband to call for help.

“Christ, Donald,” said Worden. “This bad boy must’ve caught a vein.”

“Aw yeah,” said Kincaid. “Must have.”

Outside on the stoop, the first officer was writing down particulars for his report with an expected air of indifference. But when he got to the two detectives’ sequence numbers-the departmental code that identifies officers in chronological order-he looked up in wonder.

“A-seven-o-three,” Worden told him.

“A-nine-o-four,” said Kincaid.

To make the A sequence, a man had to come on the force no later than 1967. The uniform, a D sequence himself, shook his head. “Isn’t there anyone up there in homicide with less than twenty years on?”

Worden said nothing and Kincaid went right to work. “This guy’s at University?” he asked.

“Yeah. The ER.”

“How was he doing?”

“They were trying to get him stabilized when I got here.”

The detectives walked back toward the Cavalier, but turned abruptly when another uniform, accompanied by a six-year-old boy, motioned them over to the spot where the knife had been found.

“This young man saw what happened,” said the uniform, loud enough for the child to hear, “and he would like to tell us about it.”

Worden knelt down. “You saw what happened?”

The boy nodded.

“GET AWAY FROM THAT BOY,” screamed a woman from the other side of the street. “YOU CAN’T TALK TO HIM WITHOUT NO LAWYER.”
