The weakest element in this biblio mystery concerns Janeway, who comes across too starkly as a creature of fantasy. Nowadays, we want our detective heroes to show a modicum of vulnerability; here and there, they should appear to struggle with a case as much as we might struggle with it. Or, if they must be idealized avengers of crime, then we expect them to battle not only the world’s evil but their own dark side as well. Janeway refers to a childhood bereft of love and stability—formative years that left him with a violent streak—and in one pivotal episode, he unleashes that violence. But he glides through most of this adventure with a facile mastery of both himself and his situation, and along the way we become largely indifferent to his fate.
