By the pricking of my thumbs (Unabridged ed)

This is the third Tommy & Tuppence novel, reissued in a new look to coincide with the brand new series of "Tommy & Tuppence BBC" movies.

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

But when Mrs. Lockett mentioned a poisoned mushroom stew and Mrs. Lancaster talked about 'something behind the fireplace', Tommy and Tuppence found themselves caught up in an unexpected adventure involving possible black magic!
