The Bloody Tower is a 1938 detective novel by John Rhode, the pen name of the British writer Cecil Street.

[1][2] It is the twenty ninth in his long-running series of novels featuring Lancelot Priestley, a Golden Age armchair detective.

For The Guardian E. R. Punshon wrote "in The Bloody Tower Mr. John Rhode gives another excellent example of his eminently satisfactory and solid talent."

In the grounds stand a tower, built as a folly during the eighteenth century which seems to have a strange, almost mystical power over the family.

Yet Inspector Waghorn, in the area on the trail of a gang of thieves but called in to assist, fails to find any obvious motive.
