No one gives him a second glance as he drops the gun into the greenish water.

When he arrives back at the station, he doesn’t see Benedict’s Camaro in the parking lot. He’s beaten them back.

The cop parks and walks into the building, wondering whom he hates more, Jack or that fat piece-of-shit Herb.

He climbs the stairs, heading for Benedict’s office. His plan, such as it is, is deceptively simple.

He’ll keep killing women and leaving various things belonging to Jack and Herb at the crime scenes.

Eventually, they might get close to figuring it out. When that time comes, he’ll kill them both, making it look like they’ve killed each other.

Then he’ll solve these current murders himself, framing his mortician friend Derrick Rushlo.

Sadly, Derrick won’t make it to trial.

Simple. Effective. And so much fun.

The killer makes sure no one notices as he slips into Herb’s office.

He’s looking for something, anything, that Herb will recognize when he sees it on the next victim. A tie clip, a wrist watch, a picture of his ugly wife…

“Here we are.”

In Herb’s desk drawer, he finds a library card. Without hesitating, he picks it up.

“May I help you, Officer?”

His head snaps around. Benedict is walking into the office, holding a large coffee. One of his eyebrows is raised in silent inquiry.

“Hi, Detective Benedict. I was dropping these off for you.”

In one smooth motion he slips the library card into his chest pocket and removes a small bottle of pills. He hands it to Benedict.

“Non-aspirin pain reliever?” Herb reads.

“Remember that bottle I borrowed last month?”

“Oh, yeah. Thanks.” Benedict slaps him on the shoulder, like they’re best buddies.

“Well, back to work,” he says. “TOSAP.”

“That’s what we get paid for.” Herb chuckles. “To Serve and Protect.”

Too bad there’s no one to protect you from me, old man.

Leaving Herb’s office, he bumps into Jack, causing her to spill some coffee.

“Good afternoon, Officer.”

“Good afternoon, Lieutenant.”

Bitch.

Well, if things go as planned, Herb and Jack won’t be around to irritate him for much longer.

He walks back to his desk, sits down, and takes a deep, full breath.

Close one.

He thinks about Herb Benedict, thinks about killing the man. He’s never killed someone that big before. It might actually be a challenge.

A challenge could be fun.

He decides, when the time comes, he’ll do it hands on. Mano a mano. No gun. No knife. He’ll beat him to death.

As for Lieutenant Daniels…

The good lieutenant is tough, and strong. She’ll be good for a whole evening’s entertainment, in his little plastic room on the South Side.

And maybe, if he’s careful, he could make her last the whole weekend.

It took most of the afternoon to set up the surveillance.

After playing catch-the-subpoena at the courthouse, Herb and I managed to get access to the call log from Colin Andrews’s cell phone. There were only three numbers on the list. One was to Davi McCormick’s place, one was to a call girl named Eileen Hutton, and one was to a TracFone owned by someone named John Smith.

Eileen Hutton had a record – she worked for a high-roller escort service similar to Davi’s. A search of her apartment found it empty and without any signs of foul play, and a call to her employer found them worried sick because Eileen had missed her last two dates.

A TracFone was one of those prepaid cell phones that could be bought at drugstores, electronics stores, or on the Internet. They’re a cop’s worst nightmare. It’s simple to set up an anonymous account by using a fake name and then buying phone cards with cash.

We obtained another subpoena and secured the records from the TracFone that the killer had been calling. No calls listed going out, and the only calls coming in were from Colin’s cell.

After talking at length with several people at the phone company, it proved impossible to set up any kind of tracking or tracing of the phone. But we were able to track the prepaid cards being used for minutes. The phone had been bought two months ago at an Osco Drug on Wabash and Columbus. Two weeks after that, a twenty-minute phone card had been purchased at the same place.

According to the recent bill, those minutes were due to expire tomorrow. Which meant a new phone card would have to be purchased, hopefully from the same drugstore.

Since we suspected the killer to be a cop, I was climbing the walls trying to figure out who to put on the surveillance teams. I played the sexism card, and put two teams of three female officers on eight-hour shifts. If the killer was a woman, I might have been blowing the entire stakeout, but I just couldn’t reconcile a woman cutting off someone’s arms.

Anyone who bought a phone card or a new phone at the Osco would be tailed. Anyone with access to the county morgue – cops, morticians, doctors – would be red-flagged and I’d get an immediate call.

According to the store, they sold between five and ten phone cards a day. I hoped three officers on the scene would be enough, but I did have the resources for more.

“We’re getting close,” Herb said.

“It’s still a shot in the dark, Herb. The person who owns the TracFone might not even be an accomplice. It could be someone who doesn’t even know the perp.”

“If we look at the call logs, it works out. The perp called Davi’s place at two forty-five P.M. She called him back at six fifteen. Then, at nine twenty, the perp calls the TracFone. In Eileen’s case, the perp calls her yesterday at ten thirty A.M., then again at three twelve P.M. Three hours later, at six oh two, he calls the TracFone.”

“You think he’s abducting these women, then calling someone to join the party?”

“Or to help with the disposal.”

I mulled it over. My eyes drifted to the phone. I’d called Latham three times, and he hadn’t called back. I fought the urge to check my messages again.

I’d also called my mother, twice. She still wasn’t accepting my calls.

I wonder if Alexander Graham Bell knew, back when he invented the telephone, how much control his device would have over the lives of so many people. Especially mine.

I switched gears. “We might be missing a connection between Davi and Eileen.”

Benedict flipped through his notes. “There doesn’t have to be a connection. Both have priors. The killer could have been searching for likely victims by going through arrest records. All cops have computer access.”

Chicago had several psychiatrists specifically for its law enforcement officers. Cops had the same problems as everyone, but they tended to be amplified. I’d called the three doctors in the city’s employ, and all gave me the same lecture about patient confidentiality. The off-the-record question of “Do you know of any cops who might be capable of this?” was met with three enthusiastic “yes” answers.

Herb popped something into his mouth, chasing it with old coffee. He looked at his watch.

“I’ve got to hit the road, Jack. These things kick in pretty fast.”

“You took a Viagra? Herb, can’t you give the poor woman a rest?”

“Do you want to try one? For Latham?”

I crossed my arms.

“Latham’s fine in that area, thanks.”

“You sound defensive.”

“I’m not defensive.”

“Jack, all couples have problems sometimes. I’m sure he finds you very attractive.”

“We’re not having any problems in bed, Herb. That is, when we find the time to go to bed.”

“I thought, last night…”

“Did you hear about the shooting at the Cubby Bear?”

I watched Herb put two and two together in his head.

“You know, I was thinking that might be you, but when you didn’t say anything this morning…”
