The
story begins: "It was a little way station on
the transcontinental railroad
in western Canada. Only one man worked there.He had what railroaders
call
an "OS" job. About all he had to do was "OS" trains- telegraph the
dispatcher
that they were passing his point."
In The Red Skull Ham mentions that he wouldn't mind a vacation in the Canadian Woods. Well, here it is folks. Doc and his men are on vacation! All six board a train for a trans-continental trip across Canada to British Columbia. Doc has never met his uncle, Alex Savage or his cousin, Patricia Savage who live in the Pacific Northwest. Doc chooses the train for the leisurely pace it offers. No doubt, the last several months have worn even these adventurers thin. But there will be no rest for Doc and his men. Attempts are made on their lives. A strange mark of a werewolf's face is the culprit's calling card. Doc Savage stands accused by three nervous passengers, Senor and Senorita Oveja and El Rabanos, of a brutal murder! After a second murder, the three suddenly flee from the train. Doc and his crew take up the chase. They learn that telegraph messages from Doc's uncle have been intercepted. It appears that someone is trying to keep them from reaching Alex Savage and Patricia. Doc and his men battle El Rabanos and the Ovejas, and an apparently unrelated gang of armed villains. The mystery leads to the coastal woodlands near Alex Savage's homestead! Doc and his aides arrive to find a young and beautiful Pat Savage in fear for her life, and Uncle Alex dead of what Pat describes as heart failure. Fending off constant attacks by their foes the mystery begins to unfold. They must fathom the purpose of a strange ivory cube and it's link to the lost treasure of the pirate Henry Morgan!
