The brilliantly chilling new novel by the critically-acclaimed queen of psychological suspense. When Amber Hewerdine consults a hypnotherapist as a last resort to cure her insomnia, she doesn't expect that anything will change. She doesn't expect to hear herself, under hypnosis, saying words that mean nothing to her: 'Kind, cruel, kind of cruel' - words she has seen somewhere before, if only she could remember where. She doesn't expect to be arrested two hours later, as a result of having spoken those words out loud, in connection with the brutal murder of Katharine Allen, a woman she's never heard of.
