Another wonderful addition to the Superintendent Allyn series. After a lavish treasure hunt at an English Manor House one of the guests is found murdered in a most unpleasant place, face down in the muck and mire of an open drain pipe. It is now up to Superintendent Allyn and his team (including Inspector Fox) to figure out which of the many suspects has done it. If you haven't read any of this series, you should - they are written in the classic style of Agatha Christie and Dorothy Sayers.!
This was a good mystery. Alleyn trying to solve a mystery involving some suspects of the spoiled upper class who lie and evade over and over (a bit tedious). The characters are well developed, if not always likeable.
Ngaio Marsh, New Zealand crime writer and theatre director, wrote many mysteries beginning in 1933. Love these vintage mysteries and this one was not easy to solve. The murderer was not someone I suspected at all. Not sure about the motive but it was a good, good, read.
