The Ghost Who Loved Ropes

Marsha Malone and her roommate Trudy love ropes and bondage. Mostly, they like to tie up each other and their passions for each other run deep, but neither is averse to having a man tie them; or another woman. It seems to run in the family for Marsha, because when she is unexpectedly called to the reading of her Aunt Molly's will, she learns that Molly's old house has a frightening history of pain and bondage.
More extraordinary still is Aunt Molly's assertion that she has hidden a fortune in diamonds in the house, and the only way that anyone will find them and become the sole beneficiary is with the help of the house's resident ghost. Soon, all Aunt Molly's relatives are searching for the treasure, and, bizarrely, rapidly developing a deep desire for bondage and discipline. And then people begin to disappear.
