Once upon a Murder

WHICH ONE OF THE TENANTS AT THE OAKS IS A DIABOLICAL KILLER?

WHO WROTE THE POISON-PEN LETTERS?

HOW WOULD POLLY ESCAPE THE SUFFOCATING CRYPT THE MURDERER HAD DESIGNED ESPECIALLY FOR HER?

Professor Polly Sloan had no way of knowing she was flying toward danger instead of a well-deserved vacation. She had no way of knowing that a vaguely threatening letter that she intercepted would be an invitation for victims only. She had no way of knowing that she had inadvertently crossed the path of a sadistic killer. She only knew that to break the murderous chain of events she would have to add her name to the killer's list.
