Tommy and Tuppence are at it again. This detective couple can never walk away from a mystery and these two later novels are no exception.

By the Pricking of My Thumbs: 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 . . .

Postern of Fate: Tommy and Tuppence Beresford have just become the proud owners of an old house in an English village. Along with the property, they have inherited some worthless bric-a-brac, including a collection of antique books. While rustling through a copy of The Black Arrow, Tuppence comes upon a series of apparently random underlinings.

However, when she writes down the letters, they spell out a very disturbing message: "Mary Jordan did not die naturally." And sixty years after their first murder, Mary Jordan's enemies are still ready to kill. . . .
