THE MYSTERY OF THE SEINE
by Anon. (George Hamilton Teed) · Illustrator: Arthur Jones
Other content: The Crook Specialist (article)
Notes: Audacious robberies, which include fatal shootings, are occurring in and around Paris. The sûrete asks Sexton Blake for help. The only clue they have involves suspicious activity on an island in the Seine opposite the town of Poissy. Blake goes there disguised as a fisherman, and Tinker separately in the guise of an Indian student. The youngster, while watching the comings and goings on the island, recognises The Three Musketeers and watches as they go swimming and mysteriously disappear under water. After he narrowly escapes capture, the Musketeers, believing themselves found out, become nervous and decide to commit one last crime in the region before fleeing. They rob the bank in Poissy then drive to the forest of St. Germaine where they ditch their car and change into the robes of Benedictine monks. This, though, is witnessed by Tinker, who reports to Blake that the crooks are returning to their hidden lair to fetch the rest of their loot. The detective, having deduced the location of their hideout, waits until they are in it then launches an attack. Amid the gunfire, he is wounded in the shoulder. Reggie Fetherston and Archie Pherison are both hit and captured but Algy Somerton escapes.
