In the mode reminiscent of Sherlock Holmes and his ineradicable nemesis, the virtually immortal Professor Moriarty, Inspector Juve dedicates himself to the relentless pursuit of that evil genius Fantomas. He is, as they say in petrified Paris, "Nothing. . . Everything. . . Nobody. . . Somebody". And what does he do? He "spreads terror", diabolically, craftily beyond all imagining: slashes throats of kindly old ladies; stuffs strangled British socialites into trunks; boldly robs Russian princesses in their hotel rooms; pushes witnesses off speeding trains to their deaths. Can Juve prevail against that hellish power.
