Ex-DS Dennis Milne is partnered with a former informant and running a small hotel and dive shop in the Philippines. He’s hiding out after the events that occurred in the first novel, The Business of Dying. He’s asked to kill a man due on Friday’s plane from London. Having recognized the man as the killer of his former partner, DS Asif Malik, he shoots him and then decides (implausibly) to return to London where he was the subject of an intense manhunt to wreck vengeance on Les Pope, the man behind Malik’s killing, and also the man who solicited Milne to kill the man off the plane.
The trail to Malik’s killer is convoluted and has a surprising ending, at least as far as one character is concerned. Good read. The books should be read in order.
