Comedian Dom Joly chooses Conversations with My Agent by Rob Long, the memoirs of an American TV scriptwriter, to discuss with the novelist Kate Hamer and Harriett Gilbert. Kate's new book Crushed is a dark tale of troubled teenage female friendship and her choice of book - The Vet's Daughter by Barbara Comyns - is described as suburban gothic meets magical realism. Harriett chooses March Violets by Philip Kerr.
