Eton Crop — Bill James

Stalked by shadowy figures, Simon Pilgrim fled in terror from the floating restaurant Eton Boating Song, where he discreetly sold drugs to well-to-do patrons. Now he's dead, and the police know that the drug syndicates are at war--with the Eton's lucrative market as the prize. In a high-risk move, DCS Colin Harpur and his brilliant, jealous superior, ACC Desmond Iles, put their colleague Naomi Anstruther in undercover on the Eton. But when two of her rival lovers turn up unexpectedly and blow her cover, gunfire explodes and Harpur and Iles must act with lightning speed to salvage the operation and get her out alive.
