Specialist on literature of the XIX century Брендан Дойль sets forth back for time - in 1810. He wants to listen the lecture of poet Samuel Тэйлора Кольриджа. In London he will have to run into the disfigured clowns, underground organization of beggars, reckless homunculus and magic. Дойля steal gipsies, and he does not succeed to return back in 1983. A philologist grows into a street swindler, teaches new tricks and becomes a fencer, only to survive in the dark and treacherous world of the London bottom. He affronts to poisons, bullets, black art, tobeggars, to the conclusion in the caves filled with mutants, and to the jumps in time. Дойлю will be to meet Lord Byron, creator of monsters, and wolf-werewolf, changing bodies.
