The Lake House is a 1946 detective novel by John Rhode, the pen name of the British writer Cecil Street.

[1] It is the forty second in his long-running series of novels featuring Lancelot Priestley, a Golden Age armchair detective.

Maurice Richardson in The Observer summarised it "Dr. Priestley and his white-headed boys are at it again, cosy, fussy, consequential and full of interesting ratiocination, solving The Lake House, by John Rhode.

This is a small town killing which leads to a big trial and an outstanding piece of reconstruction, including histrionics, by the Doc and his amanuensis Harold Merefield.

Another review in The Spectator felt "although without any merit of humour or characterisation, The Lake House is certainly a good mystery."
