Mansion of Mystery — Virginia K. Smiley

It was a large, brooding Victorian mansion with an aura about it of unspoken evil. From the moment lovely young Julie Travers arrived she was filled with foreboding. She was to be both governess and nurse to a strange, highly emotional child; a frail girl who had inexplicably driven all previous governesses from the house.

As days passed and Julie began to know the other occupants of Pigeon's Roost, her fear mounted. Not even the attentions of handsome Mark Evans eased her icy apprehension. Suddenly she became aware of an awesome conspiracy of silence, her nightmares became reality--and she was trapped in a bizarre charade of unending terror....

Hero: Mark Evans
Heroine: Nurse Julie Travers
