Post-war England. Two women decide to put their country above their families. Adrienne travels the world advising governments on behalf of her country. She doesn't have time for her son Daniel. Boarding school offers an answer. But for Daniel, being Jewish in an English boarding school in the 1960s is a nightmare. Eleanor has signed up as a sleeper with MI5. She and lyrical Irish builder Barrie, the love of her life, move to a perfect country cottage, and when a traumatised Daniel finds refuge there, he thinks he's found his safehouse. But both Eleanor and Barrie hide deep secrets that fracture his fragile tranquillity with terrifying consequences.
