The Croaking Raven is a 1966 mystery detective novel by the British writer Gladys Mitchell.

[1][2] It is the thirty ninth in the long-running series of books featuring Mitchell's best known creation, the psychoanalyst and amateur detective Mrs Bradley.

The title is taken from a line from Shakespeare's Hamlet "the croaking raven doth bellow for revenge".

Dame Beatrice Bradley rents a manor house in the grounds of a former Norman castle for the summer, interested in discovering more about the property which had once belonged to one of her patients.

She is soon drawn in to investigating the suspicious death of the house's last owner who died two years before.
