of London which I have described already, and also, I hope, to a certain originality of experiment in the tale of terror. The novel incorporates several inset weird tales and culminates in a final denouement of deadly horror, connected with a secret society devoted to debauched pagan rites. The three imposters of the title are members of this society who weave a web of deception in the streets of London-retailing the aforementioned weird tales in the process-as they search for a missing Roman coin commemorating an infamous orgy by the Emperor Tiberius and close in on their prey: "the young man with spectacles".
