This is the first of Ngaio Marsh's Roderick Alleyn mysteries and it contains everything that a great Golden Age mystery should. First, the house party, complete with varying guests - an adulterous wife, jealous girlfriend, mysterious Russian, etc. In this case, the country house in question is Frantock and Nigel Bathgate (a journalist) is accompanying his cousin Charles on one of the much coveted entertaining weekends, for which invitations are hard to obtain. The host intends to hold a 'murder' game, which naturally goes completely wrong, when there is a real victim. Lots of implausable plot twists (via the Russians) and an even more implausable conclusion, but the whole thing is great fun. Ngaio Marsh never cheats and you could, if you are extremely clever and keep notes, work it out. Personally, I am happy to relax in her highly competent hands and enjoy. Beware, though, you could easily get hooked on these brilliant books. Just out of interest, I read the kindle edition and it was perfectly edited - not a typo to be found.
