By the Pricking of My Thumbs by Agatha Christie

The Queen of Mystery has come to Harper Collins! Agatha Christie, the acknowledged mistress of suspense--creator of indomitable sleuth Miss Marple, meticulous Belgian detective Hercule Poirot, and so many other unforgettable characters--brings her entire oeuvre of ingenious whodunits, locked room mysteries, and perplexing puzzles to William Morrow Paperbacks. Tommy and Tuppence Beresford, Christie's delightful sleuthing duo, investigate the strange and troubling doings behind the scenes at a gothic British nursing home in By the Pricking of My Thumbs.
