Publisher's Synopsis
'The last golden crown of the Golden Age detective story' H.R.F. Keating Pressed into wartime service, Heron's Park military hospital stands three miles from the nearest town. For once the wards are silent as the inmates consider new perils in their midst. A patient dies under anaesthetic and a nurse loudly claims to know what went wrong. Soon she too meets her maker. Of the seven doctors and nurses who know the story there are now only six. Six pleasant, familiar faces, but behind one of them lurks the mind of a ruthless killer. It is up to the dishevelled, chain-smoking Inspector Cockrill to unmask the murderer.
