Now he spotted a men’s room down a deserted corridor, entered and stepped into a stall. He dug through his backpack for a change of clothing. Not many options. He slipped on worker’s coveralls and replaced the stocking cap with a Mets hat. Pulled on dark rimmed reading glasses too. Finally, he extracted a canvas gear bag, like a contractor would use, and shoved the backpack and his coat into it. He carried the bag around for this very purpose – to change his identity in case of escape.

Thou shalt be prepared to become someone else …

He eased out of the restroom and made his way to the front door. He was about to step out onto the street through the double door entry when a police car showed up, followed by two others, the tires squealing in brief skids. Officers leapt out and began speaking to every white male between fifteen and fifty near the building, asking for IDs, looking through bags.

Hell.

Soon other officers arrived, along with a large, blue and white NYPD Emergency Service truck. They formed a perimeter in the front – and presumably they were ganging at the back door and loading dock too.

Billy turned back. He shivered in anger. The policewoman’s presence, so unexpected, had ruined everything. He’d been shocked to see that it was Amelia Sachs herself, ironically looking just as steely eyed as in the photo in chapter seven of Serial Cities.  Wearing pretty much the same unsexy outfit too. Oh, he wanted so badly to get her on her back and give her one of his special mods. Angel’s trumpet. Brugmansia . Lethal quickly, but not so fast that Officer Sachs wouldn’t die in excruciating pain.

But before that he had to get out of here. The police, it seemed, were getting ready to search the building.

And he knew they’d search carefully.

The first wave of officers was moving toward the door.

Billy casually pivoted and headed to the elevator bank, where he paused and, as nonchalantly as he could, carefully regarded the building directory as if he didn’t have a care in the world – other than finding his doctor for a mole removal or colonoscopy appointment.

He was thinking furiously. The building was ten or eleven stories tall. Did it have external fire escapes? Probably not. You didn’t see those much anymore. There were probably fireproof stairwells, leading to unmarked doors opening onto alleyways. The cops would be stationed there, of course. Guns out, waiting for the perp.

Then he noticed a sign for a doctor’s office on the sixth floor.

Billy Haven thought for a moment.

Good, he concluded, and turned away from the directory as the first cops stepped into the lobby.

Thou shalt always be ready to improvise …

Lon Sellitto jogged into the main hallway of Upper Manhattan Medical Center. The elevator seemed sluggish – four people waited. Impatient patients, he joked to himself – and so he descended the stairs to the basement level, where Amelia Sachs had stopped the unsub from another attack. Stopped him with seconds to spare, it seemed. If Rhyme and Pulaski hadn’t figured out the target location the perp had been checking out earlier, they’d be running a homicide now, not conducting a manhunt.

His gold shield, on a lanyard, bounced on his substantial belly. His Burberry over his arm, Sellitto was moving fast and he was out of breath.

Fucking diets. Was there any  one that worked?

Also, gotta work out more.

Think about it later.

Downstairs he entered the cardiac care unit and walked a good fifty yards before he found the room he sought. Outside were two uniforms, male, one Latino, one black. In the room, he observed a white haired man in bed, lean, with a wrinkled – and unhappy – face. Sitting in the chair beside him was a handsome woman in her early fifties, he guessed. She was in a conservative navy suit and nearly opaque stockings, a bright scarf. Her long face was hollow and her green eyes zipped around the room uneasily. Then she glanced at Sellitto in the corridor and went back to perusing the patient. Her ruddy hands were kneading a tissue to shreds. A young blond man – resembling her slightly, son probably – sat on the other side of the bed.

Sellitto nodded to the uniforms and they stepped away from the door.

The detective asked in a low voice, ‘So. Detective Sachs?’

‘She stayed with the guard, the hospital guard, till the emergency room guys got there. Now? She’s sweeping the hallway and room where the perp attacked them, her and the guard, I mean. She already ran the scene where he was going after the vic, the woman.’ A nod toward the hospital room. Name badge: Juarez .

‘It was poison?’

‘Naw.’

‘Naw ?’ Sellitto mocked.

The kid didn’t get he was being challenged and continued, ‘Naw. The perp threw this jar from a storeroom or something at her and the guard. Broke. He’s the one got hit with whatever crap was inside. He’d been on the force. Retired from the Nineteenth.’

‘Detective Sachs wasn’t hurt,’ his partner added. Williams.

‘What kind of crap?’

Juarez: ‘They don’t know. But the first report was that it coulda been acid or something like that.’

‘Fucker. Acid?’

‘Naw, it wasn’t. Just preservative.’

Sellitto asked, ‘Hospital’s secure?’

‘Lockdown, yeah.’

The final word of that sentence prompted a glare at Juarez. He got it this time. ‘Yessir. That’s right. But they’re pretty sure he’s in the building next door. Detective Sachs saw him get out through the access tunnel. Only one place to end up. There, the doctors’ office building.’

‘And ESU thinks he’s still there?’

Juarez said, ‘He’d have to be fast, real fast, to get out. Detective Sachs called it in right away. Had the place sealed two minutes after the attack. Possible he got out, Detective, but real unlikely.’

‘Two minutes.’ Sellitto brushed at his wrinkled tie, as if that would iron the cloth flat as steel, then forgot about it. Pulling out a battered notebook, he stepped into the hospital room.

He identified himself.

The man in bed said, ‘I’m Matthew Stanton. Don’t they have security here?’ His dark eyes bored into Sellitto as if the detective had held the door open for the psycho.

Sellitto could understand but he had a job. ‘We’re looking into that.’ Which didn’t really answer the question. Then he turned to the woman. ‘And you’re–’

The man said stiffly, ‘My wife. Harriet. That’s my son, Josh.’

The young man rose and shook Sellitto’s hand.

‘Could you tell me what happened?’ the detective asked Harriet.

Matthew rasped, ‘She was just walking down the corridor, coming to visit me. And this–’

‘Sir, please. Could I hear from your wife?’

‘All right. But I’m talking to my lawyer. When we get home. I’m going to sue.’

‘Yessir.’ An eyebrow raised to Harriet.

‘I’m, I’m kind of flustered,’ she said.

Sellitto didn’t feel like smiling but he did anyway. ‘It’s fine. Take your time.’

Harriet seemed numb as she explained that the family had come to town several days ago with their son and his cousin. It was a toss up between the Big Apple and Disney. But New York, closing in on Christmas, had won. Yesterday, on the way to toy shop at FAO Schwarz, her husband had suffered what turned out to be a minor heart attack. She’d come to visit this morning and was here, on this floor, when she’d heard the policewoman calling out stop or something like that.

‘I didn’t know anybody was there. He came up real quiet. I turned around and, goodness, there was this man. Do you think he was going to, Detective? I mean, going to attack me?’

‘We don’t know, Mrs Stanton. The individual fits the description of a suspect in a prior attack–’

‘And,’ the husband said, ‘you didn’t warn people about him?’

‘Matthew, please. You can also look at it the other way. The police saved me, you know.’
