Sometimes speculative fiction creates entire new fantastical worlds. In other examples, like this book, a paradoxical provocation is introduced to a familiar world, in this case England about a century ago. The novel aspect in this story is that evil in thought or deed is manifested by the emanation of smoke from bodies. This produces a class distinction or separation; the upper class aristocrats and gentry generally do not smoke but the lower working classes are drenched in smoke that becomes a dense soot. So London becomes a particularly dark place. The protagonists are three young people exposed to lies, secrets and increasing violence and treachery. The crucial issues: rich versus poor, political differences, right versus wrong, love versus lust, and lots of guilt. This is very fine writing, reminiscent of some of Stephen King’s best stories.
