Conjure Wife: Terror, Evil, Witchcraft and Violence

Professor Norman Saylor considered magic nothing more than superstition. Then he learned that his own wife was a practicing sorceress. But he still refuses to accept the truth...that in the secret occult warfare that governs our lives, magic is a matter of life and death.
Filmed twice, as  Weird Woman  (1944) and  Burn Witch Burn  (1961), this tale of secret witchcraft on a modern college campus is as readable today as the day it was written.

Fritz Leiber's classic story of terror
CONJURE WIFE
made into the American-International movie
Norman Taylor thought it was absurd for his
beautiful wife, Tansy, to believe in black
magic. He made her throw her potions,
charms and amulets into the fire. After all, he was a college professor, a rational man who didn't believe in superstition.
Then, his troubles began ... phone calls in
the dead of night, a student who threatened
him with a gun, and a hideous gargoyle-like
creature who stalked him about the campus,
one whom he alone could see.
Slowly, an atmosphere of palpable evil encircled him until the truth could no longer be denied. There were witches all around him, conniving for his soul, lusting for his body ... and he was powerless to defend himself.

"Easily the most convincing and the most frightening of all modern horror stories"
