Are the spiritual manifestations of Professor Constable's dead daughter Mary genuine or is someone trying to sabotage his work? The only hard evidence is a wax hand bearing a set of Mary's fingerprints, but the truth must be uncovered as the apparent spirit is sapping the Professor's will with each passing hour.
Paul William Gallico (1897–1976) was a successful American novelist, short story and sports writer. Many of his works were adapted for motion pictures. He is perhaps best remembered for The Snow Goose, his only real critical success, and for the novel The Poseidon Adventure, primarily through the 1972 film adaptation.
