A powerful new narcotic, soma, appears on the streets of Paris, in the dead hands of a small-time drug dealer from Ibiza. The French police want to discover his supplier before the distribution of soma gets out of control, and they think Hob Draconian is just the man for the job. Hob is living in Paris, and business for the Alternative Detective Agency is not exactly booming. Holding his investigator's license hostage, the police send Hob back to Ibiza to search for the dealer's killer. Tracking clues through the British, American, and French expatriate communities on the island and back to Paris and London, Hob follows his leads down a path that connects many of his own friends and acquaintances on the island and cuts uncomfortably close to home. Before long, Hob is caught up in the machinations of a ruthless international drug cartel. The course of events takes a dangerous turn, and Hob finds himself facing more trouble than he bargained for.
