When the affluent Maxwell Cheyne is drugged and robbed in Plymouth, only to find his country estate inexplicably burgled of nothing at all, a perplexing mystery unfurls. What begins as a seemingly random act of petty crime quickly escalates into a far more sinister plot, drawing Cheyne into a labyrinthine chase across England and eventually to the Continent. With private detectives baffled, Cheyne eventually enlists the meticulous mind of Scotland Yard's Inspector Joseph French, who must unravel a conspiracy woven with unusual precision and audacious scope. Crofts, a master of the 'humdrum' school of detective fiction, meticulously constructs a case where the devil is truly in the details. Inspector French, arriving midway through the narrative, doesn't rely on flashes of brilliance but on an unwavering, almost forensic dedication to process, timing, and railway timetables. This isn't a story of grand gestures, but of the methodical, unglamorous pursuit of truth, offering a fascinating glimpse into early 20th-century police procedure and the satisfying slow burn of a truly intelligent, well-plotted mystery.
