This story is a product of Canning's time in Hollywood, and is written as a pastiche of private-eye pulp fiction, with all main verbs in the present tense.
The unnamed narrator has been hired by a Hollywood producer to follow an English screen-writer suspected of having an affair with the producer's wife. He sees his quarry go into the house he has just bought, and talks to a meter-reader coming out. He waits and sketches a coral tree in the garden and a bronze statue.
The next day the writer does not turn up for work. The gumshoe goes back to the house, where a team of landscape gardeners has arrived to dig up the tree. But a telephone call comes through telling them not to touch the tree. They go away. Looking round the garden, the narrator finds the writer's dead body in a shrubbbery where it has been since the previous day. Who is the guilty party?
