by E.C.R. Lorac was originally published in 1937 and recently republished in the British Library Crime Classics series, a hidden gem from the golden age of crime fiction. Chief Inspector Robert Macdonald of Scotland Yard receives an intriguing invitation to a treasure hunt from Graham Coombe, a well-known book publisher in London. When he arrives, he finds that all of the guests, mostly mystery writers, are there in disguise and introduced under pseudonyms, which makes everything a little more complicated when one of them is murdered. A second murder darkens the case even further and leaves the reader hunting for clues along with Macdonald. This is a fun, atmospheric classic to curl up with.
