Delayed Action

This planet gave him the perfect chance to commit the perfect crime—only he couldn't remember just what it was he had committed. A Company security agent is chasing a thief, when he runs out onto the planet's tourist attraction: a naturally-occurring Moebius Strip. The agent follows, and, as one might expect, gets off the Strip twenty years later, with amnesia. Then the mystery begins. A kind of a hard-boiled detective story, with a couple of double-crosses. The only thing missing is a dame. Nothing too great.
