FAMILIES CAN BE MURDERI lean in and whisper the question I have never let myself utter in twenty-three years. “Dad, did you murder Mum?”Hannah Davidson has a dementia-stricken father, an estranged TV star brother, and a mother whose death opened up hidden fault lines beneath the surface of their ordinary family life. Now the same age that Jen Davidson was when she was killed, Hannah realises she bears an uncanny resemblance to her glamorous mother, and when her father begins to confuse them she is seriously unnerved. Determined to uncover exactly what happened to her mum, Hannah begins to exploit her arresting likeness, but soon the boundaries between Hannah and her mother become fatally blurred.
