It was at the “nineteenth hole” at Allingham, a quiet but tricky links in Dorset, that Roger Bennion first met the four crack players from London. He could hold his own with them at golf, and at cards, though they did not then realise that criminal investigation was his strong suit. Then came Hugh Denton. This caused a sensation. It was obvious that the four men knew him—and hated him. Anyhow, the next day he was found shot through the head. A second murder in the "nineteenth" further complicates matters, and for a while the police are stymied. But Roger Bennion gets to work, and the grim match is soon moving swiftly to a tense and unexpected conclusion.
