The Giddy Career of Mr Gadd (deceased)

Winifred is exasperated by her (Catholic) mother’s inability to accept her conversion to Buddhism, and by her family’s determination to drag her back to her former life. But when an elderly stranger — haunted by his dead father — turns up on Winnie’s doorstep, insisting that stories she wrote as a teenager hold the key to his supernatural problems, Winnie is forced to renew acquaintance with her younger self.

Why did she write about a Mr Gadd, who died years before she was born?
Why is Chinese ancestor worship the key to solving Fred’s problems?
And why did her mother lie to her?

But most important of all, when will she feel normal again?
