The Doorkeepers
by Graham Masterton

Description:
Julia Winward has been missing in England for nearly a year. When her mutilated body is finally found floating in the Thames, her brother, Josh, is determined to find out what happened to his sister and exactly who, or what, killed her. But nothing Josh discovers makes any sense. Julia had been working for a company that went out of business sixty years ago, and living at an address that hasn't existed since World War II. The only one who might help Josh is a strange woman with psychic abilities. But the doors she can open with her mind are far better left closed. For behind these doors lie secrets too horrible to imagine.
