In World War II England, a military hospital may hide a murderer: "[Brand] could construct puzzles with the best of them" (Elizabeth George).
As German V-1 rockets rain down on the English countryside, the men and women of the military hospitals fight to stay calm. The morning after a raid, Doctor Barnes prepares for a routine surgery to repair a postman's broken leg. But with general anesthesia, there is always danger. Before the first incision is made, the postman turns purple. Barnes and his nurses do what they can, but the patient is dead in minutes. The coroner calls for an inquest. Barnes has a history of lost patients, and cannot afford more trouble. Scotland Yard Detective Inspector Cockrill is unimpressed by the staff at the hospital, which he finds a nest of jealousy, indiscretion, and bitterness. One of them, doctor or nurse, murdered the postman—and it won't be long before they kill again.
