Putney

It is the 1970s and Ralph, an up-and-coming composer, is visiting Edmund Greenslay at his riverside home in Putney to discuss a collaboration.

Through the house's colourful rooms and unruly garden flits nine-year-old Daphne - dark, teasing, slippery as mercury, more sprite than boy or girl.

From the moment their worlds collide, Ralph is consumed by an obsession to make Daphne his.

But Ralph is 25 and Daphne is only a child, and even in the bohemian abandon of 1970s London their fast-burgeoning relationship must be kept a secret.

It is not until years later that Daphne is forced to confront the truth of her own childhood - and an act of violence that has lain hidden for decades.
