The Great Railway Gold Mystery: New Adventures of Sherlock Holmes

A high-velocity kinematic impossible-crime mystery, pitting Sherlock Holmes against an adversary armed with higher mathematics, industrial engineering, and the laws of momentum.When the midnight Continental Express arrives at the Gare du Nord in Paris, the French authorities and railway officials confront an absolute physical paradox. Inside the iron-clad, oak-reinforced rolling fortress of Carriage Ninety-Four, three patent Chubb safes carrying twenty thousand pounds of unrefined Australian gold have been opened and sealed back up without a scratch on the locks or a tear upon the official wax impressions. The gold has vanished into thin air. In its place lie three hundredweight of common spherical lead shot, measured and counterbalanced to the exact imperial ounce.To the official constabulary, the crime defies explanation: the bullion van did not stop once between London Bridge and Dover, and the veteran guard locked inside the adjacent cubicle swears no living soul passed his partition.Yet where Scotland Yard sees black magic, Sherlock Holmes perceives the cold, unmistakable hand of applied science.Joined by Dr. John H. Watson, Holmes embarks on a forensic pursuit that takes them from the soot-choked alleys and illicit subterranean die-casting cellars of Bermondsey to the desolate, gale-swept marshes of the Kentish coast. Following microscopic traces of bismuth-cadmium alloys, virgin beeswax, and acoustic resonances, Holmes reconstructs a theft executed entirely at speed-engineered by an aggrieved academic prodigy who weaponized the mechanics of the railway itself to exact a ruinous revenge.
