Protagonist: Insp. John Rebus Setting: Edinburgh Rating: 3.3 When MP Gregor Jack is caught in a brothel, Rebus is sympathetic, suspecting the government official was set up. When he visits Jack’s home, he finds a nervous man – and not only because of the press coverage. Jack’s wife, who likes to indulge in sex and drug parties, is missing. Soon after, she’s found dead – and there are plenty of suspects. This is the fourth in the Rebus series. As always, Rankin brings us memorable characters and sharp dialogue.
