In addition, Byrne disclosed that, while it was only a short ride from the hospital to the police administration building, it would be the longest few minutes of Pratt’s life. To make his point, Byrne had referenced a few of the tools in the back of the van: the saber saw, the surgeon’s ribcracker, the electric shears.

Pratt understood.

And he was now on the record.

A few minutes later, when Hirsch pulled down Gideon Pratt’s pants and stained underwear, what Byrne saw made him shake his head. Gideon Pratt had shaved off his pubic hair. Pratt looked down at his groin, back up at Byrne.

“It’s a ritual,” Pratt said. “A religious ritual.”

Byrne exploded across the room. “So’s crucifixion, shithead,” he said. “What do you say we run down to Home Depot for some religious supplies?”

At that moment Byrne caught the intern’s eyes. Dr. Hirsch nodded, meaning, they’d get their sample of pubic hair. Nobody could shave that close. Byrne picked up on the exchange, ran with it.

“If you thought your little ceremony was gonna stop us from getting a sample, you’re officially an asshole,” Byrne said. “As if that was in some doubt.” He got within inches of Gideon Pratt’s face. “Besides, all we had to do was hold you until it grew back.”

Pratt looked at the ceiling and sighed.

Apparently that hadn’t occurred to him.

Byrne sat in the parking lot of the police administration building, braking from the long day, sipping an Irish coffee. The coffee was cop-shop rough. The Jameson paved it.

The sky was clear and black and cloudless above a putty moon. Spring murmured.

He’d steal a few hours sleep in the borrowed van he had used to lure

Gideon Pratt, then return it to his friend Ernie Tedesco later in the day. Ernie owned a small meat packing business in Pennsport.

Byrne touched the wick of skin over his right eye. The scar felt warm and pliant beneath his fingers, and spoke of a pain that, for the moment, was not there, a phantom grief that had flared for the first time many years earlier. He rolled down the window, closed his eyes, felt the girders of memory give way.

In his mind, that dark recess where desire and revulsion meet, that place where the icy waters of the Delaware River raged so long ago, he saw the last moments of a young girl’s life, saw the quiet horror unfold...

. . . sees the sweet face of Deirdre Pettigrew. She is small for her age, naïve for her time. She has a kind and trusting heart, a sheltered soul. It is a sweltering day, and Deirdre has stopped for a drink of water at a fountain in Fairmount Park.A man is sitting on the bench next to the fountain. He tells her that he once had a granddaughter about her age. He tells her that he loved her very much and that his granddaughter got hit by a car and she died.That is so sad, says Deirdre. She tells him that a car had hit Ginger, her cat. She died, too.The man nods, a tear forming in his eye. He says that, every year, on his granddaughter’s birthday, he comes to Fairmount Park, his granddaughter’s favorite place in the whole world.

The man begins to cry.

Deirdre drops the kickstand on her bike and walks to the bench. Just behind the bench there are thick bushes.

Deirdre offers the man a tissue . . .

Byrne sipped his coffee, lit a cigarette. His head pounded, the images

now fighting to get out. He had begun to pay a heavy price for them. Over the years he had medicated himself in many ways—legal and not, conventional and tribal. Nothing legal helped. He had seen a dozen doctors, heard all the diagnoses—to date, migraine with aura was the prevailing theory.

But there were no textbooks that described his auras. His auras were not bright, curved lines. He would have welcomed something like that.

His auras held monsters.

The first time he had seen the “vision” of Deirdre’s murder, he had not been able to fill in Gideon Pratt’s face. The killer’s face had been a blur, a watery draft of evil.

By the time Pratt had walked into Paradise, Byrne knew.

He popped a CD in the player, a homemade mix of classic blues. It was Jimmy Purify who had gotten him into the blues. The real thing, too: Elmore James, Otis Rush, Lightnin’ Hopkins, Bill Broonzy. You didn’t want to get Jimmy started on the Kenny Wayne Shepherds of the world.

At first Byrne didn’t know Son House from Maxwell House. But a lot of late nights at Warmdaddy’s and trips to Bubba Mac’s on the shore had taken care of that. Now, by the end of the second bar, third at the latest, he could tell the difference between Delta and Beale Street and Chicago and St. Louis and all the other shades of blue.

The first cut on the CD was Rosetta Crawford’s “My Man Jumped Salty on Me.”

If it was Jimmy who had given him the solace of the blues, it was Jimmy who had also brought him back into the light after the Morris Blanchard affair.

A year earlier, a wealthy young man named Morris Blanchard had murdered his parents in cold blood, blown them apart with a single shot each to the head from a Winchester 9410. Or so Byrne had believed, believed as deeply and completely as anything he had understood to be true in his two decades on the job.

He had interviewed the eighteen-year-old Morris five times, and each time the guilt had risen in the young man’s eyes like a violent sunrise.

Byrne had directed the CSU team repeatedly to comb Morris’s car, his dorm room, his clothing. They never found a single hair or fiber, nor a single drop of fluid that would place Morris in the room the moment his parents were torn apart by that shotgun.

Byrne knew that the only hope he’d had of getting a conviction was a confession. So he had pressed him. Hard. Every time Morris turned around, Byrne was there: concerts, coffee shops, studying in McCabe Library. Byrne had even sat through a noxious art house film called Eating, sitting two rows behind Morris and his date, just to keep the pressure on. The real police work that night had been staying awake during the movie.

One night Byrne parked outside Morris’s dorm room, just beneath the window on the Swarthmore campus. Every twenty minutes, for eight straight hours, Morris had parted the curtains to see if Byrne was still there. Byrne had made sure the window of the Taurus was open, and the glow of his cigarettes provided a beacon in the darkness. Morris made sure that every time he peeked he would offer his middle finger through the slightly parted curtains.

The game continued until dawn. Then, at about seven thirty that morning, instead of attending class, instead of running down the stairs and throwing himself on Byrne’s mercy, babbling a confession, Morris Blanchard decided to hang himself. He threw a length of towrope over a pipe in the basement of his dorm, stripped off all his clothes, then kicked out the sawhorse beneath him. One last fuck you to the system. Taped to his chest had been a note naming Kevin Byrne as his tormentor.
