Mr. Shaitana is well-known. He looks like Mephistopheles and often dresses like the devil at his much attended parties. But when he invites Hercule Poirot for dinner, there are only seven other people. According to Shaitana, there will be some murderers there. And that turns out to be true enough when Mr. Shaitana is the one to die.
Then, the four detectives, and one of the suspects, are on the case. It is perhaps, the first story where Ariadne Oliver and Hercule Poirot meet along with Colonel Race and Superintendent Battle from other series. Of the suspects, one is an unassuming young woman, one is an older woman obsessed with Bridge, one is a dentist, and one is an adventurer. All do have some suspicious deaths connected to their pasts but some are definitely more guilty than others.
