Strangers in Collins House (September 1967)

Victoria Winters at last feels she has a clue to her very own identification when she fits elderly Henry Collins. He secretly gives her the jewels which once belonged to his dropped love — a female Victoria strangely resembles.

After getting the gift, Victoria is instantly terrified by episodes on her existence that are masked as incidents. Surrounded by danger, Victoria miracles if she is to end up being the victim of ruthless thieves — or a hidden murderer desperate enough to keep her from learning about her past.
