Chicago buzzes when three people vanish-an art broker, a stage comic, and a well-to-do gentleman. A calm private investigator and his watchful friend follow thin clues: a safe that seems too important, a washstand that smells of greasepaint, and a poster that points from office halls to backstage doors. The chase crosses 'L' stations, club rooms, and a quiet house in the suburbs, where a story of illness hides behind drawn curtains.

There are no gunfights-only quick wits, sharp eyes, and steady footwork. As the pieces click into place, the case shifts from danger to a clever tale about identity, duty, and care, with the city's theaters center stage.

First printed in the 1920s, this brisk mystery blends light humor with human stakes and lively city detail. It moves fast and stays fair to the reader. Fans of classic city whodunits will find a tight puzzle and a clean, satisfying finish-without bloodshed, and with hearts on the line.
