Green for Danger is a popular 1944 detective novel by British writer Christianna Brand, praised for its clever plot, interesting characters, and wartime hospital setting.

(The 2016 BBC Father Brown episode 'The Rod of Asclepius' is also effectively an adaptation of the novel).

A murder takes place in a rural British hospital.

Inspector Cockrill is tasked to determine whodunit when the head nurse is killed after revealing that the death of a patient under anaesthesia was no accident.

Cockrill states at one point, "My presence lay over the hospital like a pall - I found it all tremendously enjoyable."
