The story in one page
Father Brown visits his old friend Flambeau, a reformed master-thief now living as a quiet Spanish farmer. Over wine, an American investigator asks the priest how he solves impossible crimes, such as a baronet seemingly killed by a ghost or an actor murdered behind a 'corporate alibi' of a live performance. Brown explains that he doesn't look at evidence from the outside; instead, he psychologically occupies the killer's mind until he feels their specific darkness. The stories reveal a series of bizarre puzzles, including a moat-jumping baronet and a 'Judas' face at a window, all resolved through Brown's uncomfortable intimacy with human sin.
