A stunning piece of psychological suspense, focusing on two very different women brought together by a secret from the past. Joan has a tentative grip on the world -- she's too trusting, soft-centred, cheery and straightforward. By nature and by profession, Joan is a carer, employed to look after Nina Rawle, a crisp and sophisticated woman, stricken by a long-term illness. There is a very good reason why Joan has been taken on by Nina, having to do with Nina's tangled past in Northern Ireland. How and why Nina will reveal herself to Joan, and whose part in Nina's past is truly significant, makes for a tense and twisting tale.
