Takes place in England during the 1930s. 

This mystery is about a weekend country house party with murder and mayhem. There's espionage, a jewel thief, secret agents, blackmail, and guests who are not who you think they are. Inspector Wilkins rivals Poirot and James Anderson rivals Agatha Christie. 

I found myself relaxing after the first chapter, knowing I was settling down to a good British mystery. I tried to deduce who the murderer was, but couldn't. And never did figure out the bloodstained cozy until it was revealed in the story line. When the Inspector finally revealed the murderer I was stunned.... This is how a mystery should be written! 

Excellent read. I am looking forward to reading his second title "The Affair of the Mutilated Mink."
