The Cornstarch Killer

Police are baffled by a series of murders—all the victims are men who made a practice of leering at women.

A landlord becomes both fascinated and frightened by his tenant when he learns she has the power to call down divine punishment on anyone who tries to harm her.

Discovering that she can bring down the wrath of God upon anyone who approaches her with impure intentions is a major inconvenience to a landlord who is growing increasingly wary of his boarder-- and just as enchanted.
