(From the publisher):
While visiting Tommy’s Aunt Ada at Sunny Ridge nursing home, Tuppence encounters some odd residents including Mrs. Lancaster who mystifies her with talk about "your poor child" and "something behind the fireplace."
When Aunt Ada dies a few weeks later she leaves Tommy and Tuppence a painting. Tuppence is sure she has seen the house in it before, a recognition that takes her on a dangerous adventure involving a missing tombstone, diamond smuggling, and a horrible discovery of what Mrs. Lancaster was talking about.
