Tom Bettany is working at a meat processing plant in France when he gets a voicemail telling him that his 26-year-old son is dead. Now for the first time since he cut all ties years ago, Bettany returns home to London to find out the truth about his son's death. But more than a few people are interested to hear Bettany is back in town, from incarcerated mob bosses to those in the highest echelons of MI5. Set in the same fictional London as the "Slough House" series.
