While trying to purchase an airline ticket to
Oslo at
Heathrow Airport, American journalist Kate Schechter finds herself in line behind a large blond man who also wants to get on the flight but has no identification or means of payment. The check-in counter is suddenly consumed by fire, and both Kate and the man are taken to a hospital with injuries. The man is later removed from the hospital, along with his short-handled
sledgehammer and a
Coca-Cola vending machine, and Kate checks herself out in order to find where he has gone. Meanwhile, "
holistic" detective Dirk Gently wakes up several hours late for a meeting with songwriter Geoffrey Anstey, a new client. Anstey had engaged Dirk to protect him from a green-eyed giant armed with a scythe, saying that it had to do with a contract he had signed. When Dirk arrives at Anstey's home, he finds the man's body in a chair and his head on a record turntable. Searching the home, he discovers an envelope marked with several names, all of which are crossed out except for Anstey's, and gets his nose broken by Anstey's son while trying to question him. The boy is watching a television news broadcast on the Heathrow incident, which mentions that a check-in clerk has gone missing; Dirk recognises her as his former secretary. At the private Woodshead Hospital, which caters to wealthy patients with bizarre medical afflictions, a one-eyed old man is removed and put into a van for transport to a new location during a visit by Kate. While following the van, she has a chance encounter with Dirk, who takes particular interest in her mention of a short man she saw accompanying the old patient. Returning to her home, Kate finds the blond man - actually the
Norse god
Thor — waiting for her and in need of first aid after being glued to a wooden floor and attacked by a hostile eagle. The old patient is his father
Odin, against whom he has a long-standing grudge over being repeatedly punished for losing his temper, and the short man is Odin's goblin-like assistant Toe Rag. The eagle eventually departs and makes its way into Dirk's home, trying repeatedly to attack him as he examines the document he found in Anstey's home. Even though Dirk cannot read the printed language, the formatting of the document suggests to him that it is not a contract, but rather a bill for services rendered. He discovers that the homeless persons sleeping in and around the
St Pancras railway station are actually various gods whose status has declined drastically over the centuries, due to mortals' reduced need for them. He follows them into
Valhalla, where Thor has issued a challenge to Odin but failed to show up. The challenge concerns the sale of Odin's powers to a married couple, lawyer Clive Draycott and his advertising-executive wife Cynthia, who are also in attendance. Unable to support himself in the modern world, Odin had sold his powers to finance his admission to Woodshead, where he could live in comfort. The Draycotts in turn re-sold portions of that power to other parties, but Toe Rag became involved and tried to bill them for his time. The bill was passed from one buyer to another, finally reaching Anstey, and Toe Rag had him killed by the scythe-carrying giant when the payment deadline came. Thor takes Kate to Valhalla, but all the other gods have departed and he ends up facing Odin alone. Angry over not being able to reach him by flying to Oslo, Thor had lost control of his powers, transforming a fighter jet into the eagle that harassed both Thor and Dirk, destroying the Heathrow check-in counter, and turning its clerk into the Coca-Cola machine. Thor undoes these changes to prove that he has his temper under control, but finds himself at a loss as to how to settle his disagreement with Odin. At Kate's suggestion, Odin wills his entire estate to Woodshead and is admitted as a patient for the rest of his life. The Draycotts are killed when the restored fighter jet bursts out of Dirk's home and crashes into their car. A sub-plot involves Dirk's kitchen
refrigerator, which has become so filthy that he and his cleaning lady have started trying to trick one another into opening it first. He buys a new one from a
fence and has the old one hauled away. A new god ultimately bursts out of it, created from Dirk's guilt over failing to prevent Anstey's death, and kills Toe Rag and the giant. ==Adaptations==
