A tired recyling from the Egyptian-mummy school of horrors. Scholar Thomas Ashley is accompanying fatuous Sir Harold Gregory in exploration of a new Egyptian tomb uncovered by Sir Harold when sinister Lucian Mallory shows up to join them (with servant Sam) for no apparent reason. But after Sir Harold's mummy is scandalously vandalized (someone has cut it open prematurely), Mallory invites Ashley to visit his English country estate and reveals his secret: he possesses a uniquely embalmed mummy (organs intact). What's more, however, he's been making ghastly experiments upon his servant Sam, who is now a paranoid vegetable locked up in a room. And Ashley has to wonder if these experiments are connected to two recent local murders committed by a corpse-mutilating ""monster."" Who is the monster? Sam, of course, a guinea pig for Mallory's experiments in immortality, which derive from his 4000-year-old mummy with a till-living brain. . . . Despite some fine illustrations by Stephen Fabian: dull, talky, and downright mummified.
