The Case of the Abominable Snowman is a 1941 detective novel by Cecil Day-Lewis, written under the pen name of Nicholas Blake.

Although in some respects a traditional 1930s country house mystery, it makes passing references to Second World War features such as the blackouts.

Nigel Strangeways and his explorer wife Georgia are summoned from their Devon home in deepest winter by one of her elderly relations who invites to come and spend Christmas with her in rural Essex.

The very night that Nigel first visits the manor, the owner's younger sister is found hanging in her bedroom naked.

Writing in a contemporary review in The New Statesman, Ralph Partridge felt that the novel was "written with great competence, some wit and a faint tone of condescension - a combination we have learnt to expect from the author."
