Donovan's Brain
Curt Siodmak
 The novel is written in the form of diary entries by Dr. Patrick Cory, a middle-aged physician whose experiments at keeping a brain alive are subsidized by Cory's wealthy wife. Under investigation for tax evasion and criminal financial activities, millionaire megalomaniac W.H. Donovan crashes his private plane in the desert near the home of Dr. Cory. The physician is unable to save Donovan's life, but removes his brain on the chance that it might survive, placing the gray matter in an electrically charged, oxygenated saline solution within a glass tank. The brainwaves indicate that thought&mdash;and life&mdash;continue. Cory makes several futile attempts to communicate with it. Finally, one night Cory receives unconscious commands, jotting down a list of names in a handwriting not his own—it is Donovan's. Cory successfully attempts telepathic contact with Donovan's brain, much to the concern of Cory's occasional assistant, Dr. Schratt, an elderly alcoholic. Gradually, the malignant intelligence takes over Cory's personality, leaving him in an amnesiac fugue state when he awakes. The brain uses Cory to do his bidding, signing checks in Donovan's name, and continuing the magnate's illicit financial schemes. Cory becomes increasingly like the paranoid Donovan himself, his physique and manner morphing into the limping image of the departed criminal. Donovan's bidding culminates in an attempt to have Cory kill a young girl who stands in the way of his plans. Realizing he will soon have no control over his own body and mind, Cory devises a plan to destroy the brain during its quiescent period. Cory resists the brain's hypnotic power by repeating the rhyme "He thrusts his fists against the posts and still insists he sees the ghosts." With Dr. Schratt's help, he destroys the housing tank with an ax and leaves the brain of Donovan to die, thus ending his reign of madness.
