While playing an erratic round of golf, Bobby Jones slices his ball over the edge of a cliff. His ball is lost, but on the rocks below he finds the crumpled body of a dying man. With his final breath the man opens his eyes and asks, "Why didn't they ask Evans?" Haunted by these words, Bobby and his friend, Frankie, set out to solve a mystery that will bring them into mortal danger. Taking a sabbatical from her tales of Hercule Poirot and Miss Marple, Agatha Christie published this 1934 thriller as The Boomerang Clue in her native Britain.
