The South Loop, with no entertainment beyond a few peep-shows and the city lockup, was deserted-a drunk weaving uncertainly down the street was my only companion. I crossed Wabash and went into the Pulteney Building next to the Monroe Street Tobacco Store. At night it looked like a terrible place to have an office. The hall’s mosaic-tiled walls were chipped and dirty. I wondered if anyone ever washed the scuffed linoleum floor. The lobby must create a reassuring impression on potential clients.

I pushed the elevator button. No response. I tried again. Again no response. I shoved open the heavy stairwell door, climbing slowly to the fourth floor. It was cool in the stairwell and I lingered there a few minutes before moving on down the badly lit hallway to the east end, the end where rents are cheaper because all the offices look out on the Wabash el. In the dim light I could read the inscription on the door: “V. I. Warshawski. Private Investigator.”

I had called my answering service from a filling station on the North Side, just a routine check on my way home to a shower, air conditioning, and a late supper. I was surprised when they told me I had a caller, and unhappy when they said he’d refused to give a name. Anonymous callers are a pain. They usually have something to hide, often something criminal, and they don’t leave their names just so you can’t find out what they’re hiding ahead of time.

This guy was coming at 9:15, which didn’t even give me time to eat. I’d spent a frustrating afternoon in the ozone-laden heat trying to track down a printer who owed me fifteen hundred dollars. I’d saved his firm from being muscled out by a national chain last spring and now I was sorry I’d done it. If my checking account hadn’t been so damned anemic, I’d have ignored this phone call. As it was, I squared my shoulders and unlocked the door.

With the lights on my office looked Spartan but not unpleasant and I cheered up slightly. Unlike my apartment, which is always in mild disarray, my office is usually tidy.
