She waited. Within sixty seconds her e-mail program notified her of incoming mail. It was a message from the tracking service, and it included a link to the traceroute results.

She followed the link. Abberline’s IP address was associated with the domain name SMPL.org.

According to the WHOIS database, the domain was registered to the Santa Monica Public Library at 601 Santa Monica Boulevard, Santa Monica, California.

He was using a public computer at the library, less than four miles from her house.

She remembered the overdue library books in Richard’s apartment.

He was Abberline.

Just another of his games.

She shut off the laptop so any new instant messages would be forwarded to her cell phone. She ran for her car. Luckily she hadn’t bothered to close the garage door, making it easier to make a quick exit. She shot down a side street to Venice Boulevard and headed east, then took a left onto Abbot Kinney Boulevard and a right onto California Avenue. At Lincoln Boulevard she went north.

Lincoln was always crowded, but it was the main thoroughfare in the neighborhood, and she would just have to hope the traffic wasn’t too bad.

She remembered her first online conversation with Abberline, which ended just before nine PM. The library’s main branch remained open until nine on weeknights. He must have stayed at the terminal until almost the last minute.

She was crossing Rose Avenue when her phone rang. Not an SMS alert. This was an incoming call. Caller ID showed Maura’s cell.

She couldn’t talk to Maura now. She let voicemail take the call. As she reached Ocean Park Boulevard a text came through.

Link did not work. Tried several times.

She braced the steering wheel between her elbows, freeing her hands to type a reply. Her phone, in T9 mode, allowed her to tap out words quickly, with word completion and letter prediction.

Maybe I uploaded the file wrong. Let me check.

That would buy some time. She passed Pico Boulevard and sped over the freeway. Getting close.

She couldn’t wait any longer or he might suspect something. OK fixed it. Try again.

The traffic in downtown Santa Monica was snarled. She was stuck at the intersection of Lincoln and Colorado for two minutes. Her dashboard clock clicked past 2:30.

Still no success, he wrote.

I don’t understand.

Perhaps if you explain the nature of this document?

I’d rather you see for yourself.

As would I.

Traffic was moving again. She was across Broadway, nearing Santa Monica Boulevard.

You wouldn’t be toying with me? he asked.

No.

I dislike games.

Me too.

You are a poor liar.

Turning west onto Santa Monica Boulevard. The library ahead.

I’m not lying. Why would you say that?

Around the corner. Behind the big new library complex. Praying for a place to park on the street because the underground garage would take too long.

Whores lie. And you are a whore.

She swung into a lot on the street and parked illegally in a handicapped space.

Don’t call me that, she typed. She was out of the car, ignoring the parking meter as she ran, the phone in her hand.

The library was a modernistic pile, shiny and new. She sprinted into the lobby, her shoes clacking on the glossy tile floor.

You are all whores. You and the others.

What others?

You know.

The terminals were on the second story. She took the stairs because the elevator would be too slow.

I’m down on whores and I shan’t quit ripping them.

She recognized the quotation from one of the Ripper’s letters.

He was still on the computer. He had to be here. She ran toward the periodicals room. In front of it was a line of tables arrayed with flat-screen monitors and keyboards. A handful of people sat using the machines.

Richard wasn’t one of them.

Are you there yet? Abberline asked.

Am I where?

Library.

He knew.

The link was clever. You traced me through it. I knew it was a trap.

He had left the library. Was using another computer. Somewhere in the neighborhood, undoubtedly. He hadn’t had time to go far.

But there were Internet cafés and WiFi hotspots all over, and copy stores that rented computer time. She wouldn’t find him.

Unless she could convince him to give up.

Richard, she typed, is that you?

Not my name.

Who are you?

CALL ME JACK.

The words blazed. She stared at them for a long moment, then wrote, You need help.

Doing fine without. Having the time of my life.

Please turn yourself in.

Never.

Please.

Catch me when you can.

Another quotation, this one from the letter datelined “from Hell,” which had come with Catharine Eddowes’ kidney.

She texted him again and again, but there was no response. The conversation was over.

He must have moved on as soon as he figured out what she was doing.

Unless he hadn’t. He might have lingered here. Not using a computer. Texting on a cell phone, as she was.

He would have wanted a computer to view and perhaps print out the file she claimed to have uploaded. But to continue the conversation, a cell phone would have been all he needed.

She approached a librarian and pulled out her photo of Richard, asking if he had been here today.

“Yes, I saw him. He hangs out here a lot.”

“Did you see where he went?”

“He went into the stacks.” The woman pointed to the labyrinth of books. “He looked kind of agitated. But, well...”

“He always does.” Jennifer understood. “How long ago was this?”

“A few minutes, that’s all. He’s not dangerous, is he?”

“No. Not dangerous. Thanks for your help.”

She headed into the stacks. Richard could have left since then, but there was a chance he was still here.

She moved from aisle to aisle, pausing to study every patron, even the homeless man in camo fatigues stretched out on the carpet and emitting a stench of body odor. He wasn’t Richard.

Toward the rear of the stacks there were fewer people. One of the overhead fluorescents had gone out, and another was winking fitfully. If Richard were hiding, he would probably be back here, in the solitude and the uncertain light.

She explored the darkest corner of the maze. No one was there. Yet she couldn’t escape the feeling that he was close. She could almost sense his eyes on her.

“Richard?” she whispered.

He could be hiding in one of the nearby aisles, watching her through gaps in the rows of books. But if she went chasing around aimlessly, he would stay one step ahead. He had been one step ahead all along.

Unless he wasn’t in the stacks. There was another possibility.

In the corner, under the defective light panel, was a closed door marked Employees Only. Probably it was kept locked, but Richard might be able to get in.

She approached the door. With her hand on the knob she hesitated. Suppose he was inside. He would be cornered, trapped. No telling how he would react.

But he wouldn’t hurt her. He couldn’t.

Anyway, she had to take the chance. Maura would say she was crazy.

But, hell...he was her brother.

She turned the knob, noting without surprise that the door was unlocked. It swung open, revealing a small storage closet, mops and brooms, dust pans, a vacuum cleaner, nothing else.

He wasn’t there. The closet was empty.

She didn’t know whether to be disappointed or relieved. Probably it had been foolhardy to risk entry. Probably she should be glad—
