Born to a world without welcome, Isobel observes it as warily as an alien trying to pass for a native. Her collection of imaginary friends includes the Virgin Mary and Sherlock Holmes. Later on, she meets Byron, W.H. Auden and T.S. Eliot. She is not as much at ease with the flesh-and-blood people she meets, and least of all with herself, until a lucky encounter and a little detective work reveal her identity and her true situation in life.
