The Security Warning

The Security Warning A vague tip Police headquarters receives an indirect warning that a major theft is planned in Bath. The target is identified as valuable portable property, and the Assistant Chief Constable eventually names a Turner watercolor in the Victoria Gallery. An operation takes shape Wigfull is assigned to review gallery security and proposes a discreet stakeout rather than a conspicuous strengthening of defenses. The plan is meant to catch thieves in the act. Because the warning is incomplete, the police commit resources to the apparent art target without knowing what else may be at risk. The warning is accurate enough to shape events and misleading enough to conceal its real purpose.

The Turner Riddle

The Turner Riddle A public challenge A short poem is broadcast by BBC Radio Bristol and circulated to local media. Its initials and references to security and Victoria appear to threaten the Turner painting. The wrong target Diamond interprets the verse as a possible warning about a specific person or place, but the gallery connection soon appears compelling. Wigfull treats the message as proof that a thief is taunting the police. The poem draws attention toward the guarded painting while leaving the Postal Museum exposed. Its public circulation makes the operation more than a theft: it is a performance designed to make the authorities look in the wrong direction.

The Window Cleaner

The Window Cleaner A disguised approach A thief reaches an upper window of the Postal Museum in daylight, using the ordinary presence of window cleaners to make a ladder and bucket seem unremarkable. He forces a display cabinet and takes the celebrated envelope. A missing treasure The theft becomes a national story because the cover is reputedly worth more than a million pounds. Investigators find that the thief used gloves and left few useful traces. The method is bold rather than invisible: it hides in plain sight. Police guarding the gallery painting have not protected the actual target, and the thief has turned their confidence in the tip into an advantage.

The Ransomless Return

The Ransomless Return A startling discovery During a reading at the Bloodhounds, Milo Motion opens his copy of The Hollow Man and finds the stolen envelope between the pages. The discovery happens at the precise chapter devoted to locked-room puzzles. A suspect made conspicuous Milo denies stealing it and reports the find to police. His prompt surrender makes him look less like a master thief than a person deliberately placed in the center of the case. The return does not end the inquiry. Instead, it suggests the theft and the planted discovery form a single challenge, with Milo selected as a fall guy and the police invited to misunderstand the performance.

The Thief Unmasked

The Thief Unmasked A bruised grievance Under questioning, Gilbert Jones explains that the Bloodhounds dismissed his devotion to James Bond novels. He turned that old humiliation into a carefully planned demonstration meant to prove his intelligence. The scheme exposed Jones admits stealing the Penny Black and planting it in Milo’s book. He had arranged a padlock switch so he could enter the boat later without breaking its apparent security. The elaborate stunt depended on keeping the police and the Bloodhounds focused on the puzzle. The scheme’s ingenuity cannot redeem its consequences: it led to violence, deaths, and Jones’s capture.
