The Ghost Writer Mystery

I am a Ghost. For centuries I spent my ghostly time with members of the DeLong family. The young generation decided to sell their heritage home to a developer who'd make it the focal point of a retirement residence. I decided to stay with the old house, its whispering walls and gentle ambiance comforted me. I had a notion to write my Ghostly memoirs but something was amiss. I sensed a dark aura at the residence. I needed help. I needed a confidant. I needed a Ghost Writer.
Liz Stanley, a published author, rented a small cottage on the residence property as a get-away from her busy writing life. When she found her neighbor unconscious from an overdose of drugs and alcohol she had a bad feeling. Something was wrong. The mystery deepened when the woman died in the hospital. Murdered.
Ghost moved into Liz's space and communicated by sending thoughts. The unlikely pair of sleuths, searched for evidence regarding the mysterious murder but they got more than they bargained for; residence management dealing in illegal drugs, diamond smuggling and money laundering. Bad news for the intrepid pair. and worse to come.
