Tommy and Tuppence Beresford, Agatha Christie’s wonderful sleuthing duo, investigate the strange and troubling doings in back of the scenes at a gothic British nursing house in By the Pricking of My Thumbs

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

However when Mrs. Lockett mentions a poisoned mushroom stew and Mrs. Lancaster talks about ‘something behind the fireplace,’ Tommy and Tuppence find themselves caught up within a spine-chilling experience that could spell loss of life for either of them.
