In this exclusive authorized edition from the Queen of Mystery, Tommy and Tuppence Beresford investigate the strange and troubling doings behind the scenes at a gothic British nursing home.

When Tommy and Tuppence visit an elderly aunt in her gothic nursing home, they think nothing of her mistrust of the doctors; after all, Ada is a very difficult old lady.

But when Mrs. Lockett mentions a poisoned mushroom stew and Mrs. Lancaster talks about "something behind the fireplace," Tommy and Tuppence find themselves caught up in a spine-chilling adventure that could spell death for either of them.
