The possibilities churned in my mind. Finally, realizing I wasn’t going to be able to sleep, I called Marco. I used my lapel phone because I didn’t want to wake up Lin using the omnisystem. I popped the receiver in my ear.

“Riccuccio Marco,” I said softly, and his number began to ring. With a tightening in my gut, I waited for him to answer, entwined wrists resting on my frowning forehead.

“Yeah?” Marco answered in a groggy voice after five rings.

“Okay,” I said, barely able to get the word past my heart, which pounded in my throat.

“Angel?”

“Yes.”

“Okay what?”

“Okay,” I repeated impatiently. “I’ll do it.”

There was a long pause. He said, more alert, warmly, “Okay.”

“But only as an experiment.”

“How will I know you aren’t going to go out behind my back?”

“I’ll put away my Glock,” I magnanimously offered. “I never leave home without it, at least not when I’m on a job. I rarely use it and have never killed anyone, but it’s like insurance. You know that if you don’t have it, you’ll need it. No Glock, no retribution jobs.”

“Can you resist the urge to retrieve it in a pinch?”

“I’ll put it in my bank safety deposit box. You can be my witness. In fact, I insist. I want to make sure I get full credit for this charade. I’ll take a vacation for one week, but I want something concrete in return.”

“What?”

“If I go seven days without taking on a retribution job, you have to have sex with me.”

“Ah, such a price to pay,” he said, teasing.

“I mean it. I have to have some motivation here.”

He let out a sexy chuckle. “Okay. It’s a deal. You really want to do this?”

“Sure,” I said lightly. “It’ll be a cinch.”

Boy, was I ever wrong.

Mirandized

Six days, twenty-two hours and twenty-three minutes into my agreement with Marco, my lapel phone rang. Waking from a deep sleep, I slammed my hand on the bedside table, feeling for the noise. At the same time I managed to blink open one eye and saw 3:12 a.m. reflected on the ceiling.

“Who on earth…?” I muttered as I grabbed the tiny round phone. Plugging the receiver in my ear, I groused, “What?”

“Angel?” came a gruff and vaguely familiar voice.

“Who is this?”

“Roy.”

I went instantly alert. Roy Leibman was one of Chicago’s best retributionists. I couldn’t imagine why he was calling me at this hour. I propped myself up on one elbow.

“What is it, Roy?”

“I need help,” he whispered.

The hair on my neck sprang up. Roy had never asked for help from me before. He was fifty-five and I was twenty-eight. He’d been my mentor. He shouldn’t need help. That’s not how our relationship worked. “Where are you, Roy?”

“At the Cloisters. Can you come?”

I glanced up at the red numbers reflected on the ceiling. It was now 3:13 a.m. I was an hour and thirty-five minutes away from seven days of abstinence from my work. If I answered Roy’s call for help, I’d have to start all over again. Since I was self-employed, I could take off as much time as I needed. And I’d enjoyed hanging out with Lin. We’d done everything from making sand castles on the beach to moonwalking in the Virtual Dome. But I couldn’t afford to be unemployed forever. More importantly, how could I not help a colleague in need? Besides, what Marco didn’t know wouldn’t hurt him—or me—would it?

“I’m on my way, Roy.”

“How fast can you get here?”

“I’ll take a chopper cab. Ten minutes, tops.”

Chopper cabs were expensive as all get out, and I splurged on them maybe once a year. But Roy needed me and I was determined to be there for him. Fortunately, there was a cab stand on the roof of the Music Box theater, which was just a few blocks north on Southport.

I dressed fast, wishing I had more than a knife and a whip to attach to my utility belt, woke Lola and talked her into moving from her bed downstairs to mine in case Lin woke up. Then I ran the ten-block distance like athletes used to when humans still dominated the Olympics. When I climbed into the cab, whose blades whooshed overhead, the driver’s sidelong glance looked like one he reserved for a con artist who was going to shake him down after takeoff.

“Don’t even go there,” I said, pulling out my CRS identification card. Then I held out my cash chip. “And, yes, I can afford it. Chicago and State. Pronto.”

“Yes, ma’am,” he said with a faint East Coast accent. “Buckle up, please.”

Like I had a choice. He pushed a button and two belts crossed over my chest and battened me down. While we zoomed up and over the sprawling north side of Chicago, I tried not to imagine the worst and found myself reading the cabdriver’s certificate.

Herbert Banning IV. He was a Harvard grad. So many of them flew chopper cabs these days. Ivy League degrees were quaint relics of a past when a well-educated human could still outthink a computer. While a Harvard pigskin looked impressive hanging on the wall, it was no guarantee of a job, as was, for example, a certificate from a Vastnet Nanotechnology program.

I was hoping to help Roy and get back to my place before the clock struck day seven. And Herb was fast, God love him. He’d put his philosophy degree to good use. We flew well above the old-time skyscrapers, like the Chicago Tribune building and the Sears Tower, but below the executive level of the newer 200-story buildings, like the AutoMates Starbelisk and the Morgan’s Organs Surgery Center. Fortunately, only taxis and emergency vehicles were allowed in the downtown skyways, so we didn’t face too much traffic. Before I knew it, Herb settled his small, yellow chopper on a taxi pad in the heart of the Loop. I zoomed down the building’s outer elevator and ran hard to Chicago Avenue and State Street.

The buildings were so tall in this quadrant that city officials kept the streetlights on around the clock. Like Victorian gaslights, they did little to quell the canyonlike darkness of the streets. And since this once fashionable part of town had fallen on hard times—with free rangers sleeping in well-appointed cardboard boxes, methop junkies shooting up as if they were in the privacy of their own bathrooms, and emaciated hookers lurking in the shadows—it had a vaguely Dickensian aura.

When I reached the entrance to the alley that led to the Cloisters, I called out, “Roy?” as I stepped through the trash-strewed passageway. Rotting food and urine assailed my nose, which I covered with the back of one hand as I tiptoed through a brackish liquid I didn’t want to identify. It had rained earlier, and a trickle—blessedly fresh and silvery—still flowed down a drainpipe, spilling over the broken asphalt.

I focused on the cleansing overflow as I made my way toward the end of the alley. I’d almost reached the open courtyard, where I suspected Roy awaited my help, when I was greeted by the one thing in this world that could make me want to turn and run.

“A rat,” I whispered. Not just any varmint, but a rad rat. Rad as in radiation, not trendy. Rats are never in style.

About twenty years ago some idiot Director of Public Health decided the city’s rat problem had reached apocalyptic proportions and solved it by feeding the nasty critters radiation pellets. A few—the toughest and smartest—survived, mutated, and spawned offspring so large they could have registered with the American Kennel Association.

One of their descendants stood ten feet away from me right now, the size of a pit bull, daring me to pass. That’s what I hated about rats. They had attitude, in addition to beady eyes, creepy tails and vicious teeth.

“Get out of my way!” Out of habit, I reached for the Glock that wasn’t there. I seldom used it and had never killed anyone, but it was a menacing weapon to wave around. Instead, I pulled out my whip and cracked it in the air. The rat flinched, but waddled closer.
