The author of popular mystery stories has made his reputation by devising imaginative ways in which a killer can leave his victim in a room with all the doors and windows locked up tight. When the author is found dead ... murdered in his own locked studio ... Detective Inspector Donald Burke rules out murder until Hodgkiss views the scene. Hodgkiss soon provides a solution even more ingenious than any the author ever dreamed up. After playing a round of golf Hodgkiss and Donald Burke go to the change room where they arrive to hear the tail end of a conversation between two other players. But it is not just what they hear but the manner in which one of the other players was putting on his shoes that gives Hodgkiss the clue to solve a nasty murder that happens soon afterwards. When the man's body was found there was no doubt that death was due to a fall. But where did he fall from? The office building where he worked or the block of flats where he was a regular participant in drug-fueled orgies. Hodgkiss leaves the matter in no doubt.
