has been massacred (presumably by the rebels). Despite being told not to by Captain Scott, Mrs. Wyatt leaves the carriage and finds one survivor, a baby concealed by his mother's body. The next morning, the train must stop because a portion of the track has been blown up. Mrs. Wyatt spots the signaling flashes of a heliograph atop a mountain summit, and everyone quickly realises that the Muslim rebels are sitting in ambush in the surrounding hills. With track repairs barely finished by Captain Scott, the train gets away under a hail of gunfire. Gupta is wounded but survives. Later that day, while stopping to refill the engine's water tank, Scott walks into the pump house to find Van Leyden allowing Prince Kishan to stand dangerously close to the pump's rapidly spinning flywheel. In the evening Van Leyden refuses alcohol and the group correctly deduce he is Muslim. He explains this by saying he is half Indian. During the night, Mr. Van Leyden again approaches the prince, only to notice Lady Windham watching him. The train reaches a bomb-damaged bridge.

Afterward, Scott accuses Van Leyden of trying to kill the prince, and he places the reporter under arrest. After that, Captain Scott, under Gupta's guidance, carefully maneuvers the train across. Later, while going through a tunnel, Van Leyden uses the opportunity to overpower his guard. He uses a Maxim machine gun to threaten the passengers and now declares his loyalty to the Muslim cause. He is unable to kill Prince Kishnan because the boy is with Captain Scott in the locomotive's cab. Scott returns to the carriage with the young prince after spotting more rebel heliograph signals, but they are saved when the machine gun is knocked off balance by a kick from Mr. Bridie. Scott crawls up the carriage and starts to fight him. The two men end on the roof. At the climax of the fight a shot rings out: Mrs. Wyatt has shot Van Leyden with one of the rifles. He
