Nothing will poison the present like lies from the past. Sisters Charlotte and Jennifer have a history of amusing misunderstandings about attempted suicide. Their granny, Bertha, is wrapped in memories of London in the 1920s, when she and her sister, Jemima, brought new meaning to betrayal. Bridging the two, Bertha’s daughter, Deirdre, is shaped by the night a Nazi bomb destroyed the entire street, and uncovered one of those poisonous lies.
