In the fourth of Paramount's "Bulldog Drummond" action-thrillers, the intrepid adventurer (John Howard) makes the grizzly discovery of a severed hand. Even more startling, attached to the wayward limb is a case filled with hextonite, a new and highly explosive substance desired by the enemy in general and one Draven Nogais (Frank Puglia) in particular. With his faithful servant, Tenny (E.E. Clive), fiancée Phyllis Clavering (Louise Campbell), and friend Algy Longworth (Reginald Denny) along for the ride, Captain Drummond trails the villain on board a train leaving Victoria Station for Paris. At first, the wily Nogais manages to elude his pursuers by disguising himself as a woman, but his plans to escape with the explosives are halted on the ferryboat to France. Despite the relative brevity of his role as Scotland Yard inspector Neilson, John Barrymore earned star billing in this series entry, which was based on H.C. "Sapper" McNeile's 1932 novel The Return of Bulldog Drummond. ~ Hans J. Wollstein, Rovi
