Marsh Ngaio. Died in the Wool

Died in the Wool is a detective novel by Ngaio Marsh; it is the thirteenth novel to feature Roderick Alleyn, and was first published in 1945. The novel concerns the murder of a New Zealand parliamentarian on a remote sheep farm, said to be located near Mount Cook. Like the previous novel in the series (Colour Scheme) the story takes place during World War II with Alleyn doing counterespionage work. The format of the book is somewhat unusual, in that Alleyn does not arrive at the scene of the murder until fifteen months after it has taken place, and much of his detecting is founded upon stories told him by the chief witnesses in the case.
