Grandville
 The book begins with a chase in the streets of Paris, also known as Grandville, in which British diplomat Raymond Leigh-Otter (an otter) escapes from a group of assassins. The action then cuts to Leigh-Otter's house, in which he is found shot dead and the local police are inspecting the body. Detective Inspector Archie LeBrock of Scotland Yard, a large, heavily built badger, arrives with his assistant, Detective Roderick Ratzi (a rat), and deduces that Leigh-Otter was in fact murdered, after LeBrock notices that Leigh-Otter is holding the gun in his right paw when in fact he is left-handed. Thus, they go to Paris in order to investigate. After LeBrock and Ratzi check into their hotel, they learn that Leigh-Otter often met up with a female guest, Coco (a very attractive cat), the dresser for music hall star Sarah Blairow (a badger). After further investigation they learn that others have also committed suicide, including Coco. As LeBrock goes to meet Sarah, he finds that some assassins have come to kill her. LeBrock gets rid of them and learns that they are working for an organisation called "The Knights of Lyon". LeBrock tells Sarah to go into hiding while he and Ratzi try to solve the case. While LeBrock attempts to find more information by interviewing the British ambassador, Honourable Citizen Turtell (a tortoise), Ratzi learns the Knights of Lyon are a medieval religious cult possibly connected to the Knights Templar. They visit the Robida Tower ground zero site, which had been bombed by British anarchists, causing tension between Britain and France. Two assassins approach LeBrock, who makes his way to a Turkish bath. LeBrock stops them and learns that the assassins do not know who they are working for, knowing them only as "The Knights". LeBrock kills them. Ratzi investigates another of the suicides, that of Professor Tope (a mole), pioneer of automaton engineering. After talking to his son, they learn he had an assistant called Snowy Milou (white Wire Fox Terrier). After searching Tope's old lab, LeBrock receives a telephone call from Sarah asking him to visit, because she is worried about her safety. She seduces LeBrock after he arrives and the two make love. The next day, LeBrock learns that Milou has become an opium addict and drug dealer. Ratzi uncovers a photograph which features Tope and several other public figures: Jean-Marie Lapin (a rabbit), a far-right nationalist politician and now Prime Minister who came to power following the bombing of Robida Tower, promising a "War on Terror"; Madame Krupp (a wombat), an arms manufacturer and newspaper owner; the Archbishop of Paris (a chimpanzee); Reinhardt (a rhinoceros) the Minister for War; and Hyen (a hyena), Chief of Police and Secret Service. LeBrock believes they are the Knights of Lyon and goes to investigate the Archbishop. LeBrock meets up with Milou and learns from him the whereabouts of the Archbishop. LeBrock and Ratzi capture the Archbishop, tie him to a chair and threaten to kill him by setting fire to him. LeBrock deduces that the attack on Robida Tower was organised by the Archbishop and the other Knights (with the help of Tope), who used the British anarchists as scapegoats. Under pressure, the Archbishop tells them that they did it because they believed they could protect French society from decadency and atheism by uniting them against a common enemy. An attempt to unite the people by having a war in French Indo-China had failed, so the Knights began to spread stories of a British super-bomb aimed at Paris. Their final plan is to launch a skyship from Krupp's estate and fly it into the Paris Opera House, where thousands will be watching the Trans-Empire Song Contest. Afterwards, LeBrock sets the Archbishop on fire, killing him. Outside, LeBrock tells Ratzi that he believes that Leigh-Otter was not a diplomat, but a member of the British Secret Service trying to stop the Knights' plan. As LeBrock and Ratzi arrive back at the hotel, they receive a message from Sarah saying that she is in danger. The two arrive at her hideout to find she is being held captive by the assassins. During a shoot-out, Sarah is killed and Ratzi badly injured. The following morning, LeBrock asks a human bellboy at the hotel to collect some things for him - things he will use to make bombs. LeBrock makes his way to the Krupp estate, where the Knights are preparing for the attack on the Opera House. LeBrock sets off his bombs and shoots Krupp, Hyen, Lapin and Reinhardt. Krupp's dying words, to LeBrock, are that the Knights were loyal to the Emperor. He realises that they are not "The Knights of Lyons", but "The Knights of The Lion", the lion being Emperor Napoleon XII, the head of state. LeBrock is hit over the head with a chair by Reinhardt, who was not dead but only injured. Reinhardt makes his way to the skyship and prepares to leave. LeBrock follows him and grabs hold of the skyship as it takes off. Not seeing LeBrock, Reinhardt sets the skyship's course and prepares to jump out. As he opens the door, LeBrock jumps in. Reinhardt charges at him, but falls out of the door. As he falls, LeBrock shoots him dead. LeBrock then changes the skyship's course, crashing it into Napoleon's palace. The next day the public learns the truth about the Knights and the attack on Robida Tower, with some wondering if a revolution might happen following the news. LeBrock meets up again with Ratzi in hospital.
