It is not for you to exact vengeance on my behalf. Remember that.'

When successful novelist Christabel Strange dies suddenly aged 32, the bequests are hard to fathom. She leaves one wing of the ancestral home to good friend Marcia Wentworth for her ongoing use; the rest of the house remains in the hands of her mother, grandmother and siblings. Christabel made it known that Marcia would write her biography, but leaves her sixteen volumes of meticulous diaries to wily eccentric Grandmother Strange, who loathes Marcia and refuses to allow her to see them. Dr George Caradew, Christabel's childhood friend, finds himself between opposing and increasingly hostile camps, and begins to wonder why Christabel behaved in such a peculiar way, and whether her death was really due to a fever. The possibility of foul play becomes a certainty when another murder occurs and a volume of the diaries is stolen. Gradually, Caradew pieces together the clues to Christabel's hidden life.

She lived in St Mellons in Wales with her partner Dr Liliane Marie Catherine Clopet, a family physician and author.
