A dastardly ambush … a young witness fleeing … And Mister Bluff, wounded , is carried away by the current of the river. Another dramatic adventure of Mark and of his Ontario Wolves, engaged this time in opposing an underhand sabotage action against the American garrison of Wolf Pass … “Illusion is a force that keeps you alive, but disillusion is a greater killer than a thousand mortal wounds”. Who other than Gufo Triste could have commented on the death of Major Peacock and the obscure event of the Viking Tomb with such eloquence ? The rich gentleman Mr Cox and his son, who are protected by a medallion incised with runic characters, search for the ancient tomb of the warrior of the North. But the protection granted to them by the necklace would have been of little support, had Mark, Mister Bluff and the wise sachem not given their help in this matter !
