BENEATH THE DEADLY BLADE
A dying man arrives at 221B Baker Street. An eccentric burglar scandalizes Sussex. The legendary sword of the prophet Mohammed surfaces, then disappears...
This bizarre sequence of events propels Sherlock Holmes and Dr. Watson to the back canals of Venice, the shadowy world of Berlin, the lurid alleys of Cario, an the Valley of the Kings––in search of the sacred silver sword and the false prophet who may trigger a holy war in the Middle East, unless the dauntless Holmes can bring the scoundrel to ground and halt his fiendish scheme!
