The story is a standard Christie, a litle bit creepy and sprinkled with clues. I have given it two stars rather than three because of the reader, Alex Jennings. The narrative was fine the voices of Tommy and Tuppence okay, but other voices varied from the too soft to hear without blasting out my eardrums on the other passages (Philip Stark) to the virtually unintelligible (the general and the Welshman)to the downright inappropriate. Mrs Boscowen is described as having a deep, attractive voice. Jennings gives her an ugly nasal drawl.
Audio books do depend so much on the reader.!
