Dirk Gently has fallen on hard times and dresses as a gypsy woman, using his irritatingly accurate clairvoyant powers to read palms. He is saved when a frantic client turns up with a ludicrous story about being stalked by a goblin waving a contract accompanied by a hairy, green-eyed, scythe-wielding monster. When Detective Superintendent Gilks decides a headless body found in a sealed room is the result of a particularly irritating suicide, Dirk is plunged into a mystery where the interconnectedness of all things is tested to the limit.
