Mary's Little Lamb

A lunatic has escaped from an asylum, someone who had never been allowed to attend his local public school. The teacher of the school has disappeared, just vanished without a trace. Two retired university professors have been killed at their doorstep by an ax murderer, and their daughter, Mary, has been hired to replace the missing teacher. The town minister has a vision that Mary will be killed too, and to save her, the school must remain closed. She is as determined to teach as the minister is determined she not do it, and the school remain closed.
