Ask A Policeman by Helen de Guerry Simpson, John Rhode, Dorothy L. Sayers, Anthony Berkeley, The Detection Club, Gladys Mitchell, Milward Kennedy

4.0

This is a pleasant little train wreck—a murder mystery written by committee (but a committee of fine Golden Age mystery authors). One author sets the stage, putting forth a classic murder scene in a country house with a tight timetable and an impeccable array of suspects. Then 5 more authors offer sections having sleuths investigate and "solve" the mystery (with the added twist that they swap sleuths with each other). As each adds to the evidence, the level of implausibility builds, which adds to the entertainment (for me, anyway).

I wish I had been familiar with more of the authors and detectives involved. I know Dorothy Sayers and her Lord Peter Wimsey very well, but of the rest involved I only know Gladys Mitchell and her Mrs. Bradley by reputation (but I really want to track her books down).
