PI Grace Jones - committed to truth, justice and a pressing need to re-stock her larder - is asked to find a missing person. But her client Henry Summerstone has been blind for years. He has no idea of the name of the girl he is trying to trace, what she looks like, where she lives and works; in fact he's not even sure she is missing. But he's concerned about the whereabouts of the young jogger who talks to him on his solitary early morning walks, and he's offering cash - an offer Grace finds hard to turn down. Before long, she's got a lead on the girl - several leads as it turns out - but each time she gets close Miss X slips away. But Grace is a Girl who knows how to persevere and she struggles on, becoming entangled with squatters, invisible pigs, a 12 year old estate agent and the man of her dreams - who unfortunately seems also to be the man of his wife's dreams.
