The lives of the talented Aubrey children have long been clouded by their father's genius for instability, but his new job in the London suburbs promises, for a time at least, reprieve from scandal and the threat of ruin.

Mrs. Aubrey, a former concert pianist, struggles to keep the family afloat, but then she is something of a high-strung eccentric herself, as is all too clear to her daughter Rose, through whose loving but sometimes cruel eyes events are seen. Still, living on the edge holds the promise of the unexpected, and the Aubreys, who encounter furious poltergeists, turn up hidden masterpieces, and come to the aid of a murderess, will find that they have adventure to spare.
