The city would never forget.

He was standing over a dead black kid, no witnesses and no partner. He was drunk. A dead black gangbanger, killed execution style with a slug from his service Glock, a weapon that, at the moment, he could not account for. For a white cop in Philly, the nightmare couldn’t get much deeper.

There was no time to think about it.

He squatted down, looked for a pulse. There was none. He got out his Maglite, cupping it in his hand to keep the light as hidden as possible. He looked closely at the body. From the angle, and the appearance of the entry wound, it looked like a through and through. He found the shell casing in short order, pocketed it. He searched the ground between the kid and the wall for the slug. Fast-food trash, sodden cigarette ends, a pair of pastel condoms. No bullet.

Above his head, in one of the rooms overlooking the alley, a light flipped on. Soon there would be a siren.

Byrne picked up the pace of his search. He tossed garbage bags, the foul stench of rotted food nearly making him gag. Sodden newspapers, wet magazines, orange peels, coffee filters, eggshells.

Then the angels smiled on him.

Next to the broken shards of a smashed beer bottle, was the slug. He picked it up, put it in his pocket. It was still warm. He then took out a plastic evidence bag. He always had a few in his coat. He turned it inside out and laid the bag over the entrance wound on the kid’s chest, making sure that he got a thick smear of blood. He stepped away from the body and turned the Baggie right-side out, sealing it.

He heard the siren.

By the time he turned to run, something other than rational thought had taken over Kevin Byrne’s mind, something much darker, something that had nothing to do with the academy, the manual, the job.

Something called survival.

He started down the alley, absolutely certain he had overlooked something. He was sure of it.

At the mouth of the alley, he glanced both ways. Deserted. He sprinted across the vacant lot, slipped into his car, reached into his pocket, and turned on his cell phone. It rang immediately. The sound nearly made him jump. He answered.

“Byrne.”

It was Eric Chavez.

“Where are you?” Chavez asked.

He wasn’t here. Couldn’t be here. He wondered about cell phone tracking. If it came to it, could they track where he was when he received this call? The siren grew closer. Could Chavez hear it?

“Old City,” Byrne said. “What’s up?”

“Call just came in. Nine-one-one. Someone saw a guy carrying a body up to the Rodin Museum.”

Jesus.

He had to go. Now. No time to think. This was how and why people got caught. But he had no choice.

“I’m on my way.”

Before he left, he glanced down the alley, at the dark vista on display there. In the center was a dead kid dropped into the middle of Kevin Byrne’s nightmare, a kid whose own nightmare had just breached the dawn.

TUESDAY, 9:20 PM

He had fallen asleep. Ever since he had been a child in the Lake District, where the sound of rain on the roof was a lullaby, Simon had been soothed by the clatter of a storm. It was the car backfiring that awakened him.

Or maybe it was a shot.

This was Gray’s Ferry, after all.

He looked at his watch. An hour. He had been asleep an hour. Some

surveillance expert. More like Inspector Clouseau.

The last thing he remembered, before being startled awake, was

Kevin Byrne disappearing into a rough Gray’s Ferry bar called Shotz, the

kind of place where, when you walk in, you go down two steps. Physically and socially. A ramshackle Irish bar full of House of Pain types. Simon had parked on a side street, partly to keep out of Byrne’s line

of sight, partly because there wasn’t a space in front of the bar. His intention was to wait for Byrne to emerge from the bar, follow him, see if he

pulled over on some dark street and lit up a crack pipe. If all went well,

Simon would have snuck up on the car and snapped a picture of the legendary detective Kevin Francis Byrne with a five-inch glass shooter between his lips.

Then he would own him.

Simon had gotten out his small, collapsible umbrella, opened the car door, spread the umbrella, and sidled up to the corner of the building. He peered around. Byrne’s car was still parked there. It looked as if someone had broken the driver’s window in. Oh Lord, Simon thought. I pity the fool who picked the wrong car on the wrong night.

The bar was still packed. He could hear the dulcet strains of an old Thin Lizzy tune rattling the windows.

He was just about to head back to his car when a shadow caught his attention, a shadow darting across the vacant lot directly across from Shotz. Even in the dim light thrown by the bar’s neon, Simon could recognize Byrne’s huge silhouette.

What the hell was he doing over there?

Simon raised the camera, focused, snapped a few pictures. He wasn’t sure why, but when you shadowed someone with a camera and tried to assemble the collage of images the next day, every image helped in establishing a time line.

Besides, digital images were erasable. It wasn’t like the old days when every snap of a thirty-five millimeter camera cost money.

Back in the car, he had checked the images on the camera’s small LCD screen. Not bad. A little dark, of course, but it was clearly Kevin Byrne coming out of that alley and across the lot. Two of the photographs had been against the side of a light-colored van, and there was no mistaking the man’s hulking profile. Simon made sure that the image was imprinted with date and time.

Done.

Then his police band scanner—a Uniden BC250D, a handheld model that had more than once gotten him to a crime scene ahead of the detectives—crackled to life. He couldn’t make out the details, but a few seconds later, when Kevin Byrne took off, Simon knew that whatever it was he belonged on the scene.

Simon turned the ignition key, hoping that the job he had done securing his muffler would hold. It did. He wouldn’t be sounding like a Cessna aircraft while trying to shadow one of the city’s savviest detectives. Life was good.

He put the car in gear. And followed.

TUESDAY, 9:45 PM

Jessica sat in her driveway, exhaustion beginning to take its toll. Rain hammered the roof of the Cherokee. She thought about what Nick had said. It had crossed her mind that she not had gotten The Talk after the task force was formed, the sit-down that would’ve started: Look,
