Ellie's husband Thomas, a retired minister, is suspicious when he receives not one but five letters advising him that he has been bequeathed money by five different people in their wills. He barely knew three of his benefactors, and what could possibly connect him to the other two strangers?

Sensing something isn't right, and with Thomas's reputation at stake, Ellie investigates but is soon distracted, not only by the problem of trying to ease Hetty, a difficult woman who's recently taken refuge with them, out of their house, but also by her daughter, Diana, who's in trouble again. As Ellie finally starts to make progress with her enquiries, she is about to uncover some disturbing truths - and in doing so, find herself in great danger . . .
