'"The Law of the Knife" again sees "Leathermouth," otherwise Colonel Gantian, Secret Service agent, confidant of Scotland Yard, at work in investigating the nefarious work of Russian agents in England. Chief among them is a juggler, whose feats of knife throwing on the stage are endowed with a sinister aspect when Colonel Gantian narrowly escapes death by that means, and, in particular, when a young woman in the clutches of the gang is killed on the stage when one of the knives with which the thrower Is "outlining" her body against a wall, penetrates her eye. Leathermouth is a danger to the Soviet and must be got rid of. The girl had warned him. So the murder takes place, but is attributed to death by misadventure, the juggler declaring that the girl had moved her head.

'The story of the attempts by the agent of the Russian Commissar, with whom Leathermouth has come into conflict, are told by a hand skilled in that class of narrative, and it will be found that, combined with the excellent style in which the various characters are handled, the serial will hold its interest unflagglngly from beginning to end.'
