When she goes up to Maine to take care of Priscilla Scott, a spunky old lady recovering from a stroke, Nurse Hillary Holt’s life becomes a jumble of love and fear. For there, at the isolated castle known as Eagle’s Watch, Hillary meets handsome Dr. Kent Harry, who is clearly attracted to her but cannot express his feelings.

Hillary also meets Priscilla Scott’s greedy relatives, all of whom are convinced she’s after the old lady’s wealth. Even Mitchell, the most appealing family member, is frankly interested in money and assumes the young nurse feels the same way. Worse yet, he — or one of the others — seems ready to commit murder to get rid of Hillary!

Helen Jervis loved the moors so much that she jumped at the chance of nursing old Ethan Hesketh in Braunston Manor. But she found the old house a nerve racking place. Milly Rolph, the maid, refused point blank to sleep in the manor, and the girl was reluctant to say why. Helen was not a nervous person, and she became attracted to Doctor Keith Spencer. But strange events were taking place under cover of darkness, and it needed a terrifying climax to clear the situation.
