Final Appointment

John Bentley is working on a story about death threats to Hubert Gregg. Inspector Liam Redmond doesn't think much about his wild theories, until it turns out there are two unsolved murders in the same date in each of the preceding two years. They figure the connection, but then it turns out that none of their three suspects could have done it: one is dead, one left for Australia, and the third one, Sam Kydd, isn't the type. Meanwhile, back at the office, Eleanor Summerfield is Bentley's girlfriend and the agony aunt columnist, both positions she wishes to change.

It's a terrific little mystery, with Bentley and Redmond investigating a murder that hasn't taken place, and the twist is one I didn't see coming. It's one of those cheap Quota Quickies where everything works, and a very good time indeed.
