One could wish the central thesis of this story carried more conviction, for it is a readable enough yarn dealing with questionable facts. Don Murray, alone -- by his own desire at the Murray's hunting camp, frees a young grew wolf from a trap, nurses it back to health, and tames it to a degree of devotion unusual even in a dog. Don insists that Lance is a German shepherd dog -- and by the end of the story, Lance has merged his wolf characteristics in those of a highly intelligent dog. Plenty of adventure- but there seems to be lack of technical knowledge that youngsters who are scientific in their approach to the subject will readily spot. Just a touch of the Terhune school of glamourizing the dog may win less exacting readers.
