Never tell Mac Faraday not to do something.Spencer's police chief, David O'Callaghan, learns this lesson the hard way when he orders Mac Faraday to stay away from the south end of Spencer's mountaintop-even though he owns the property. It doesn't take long for Mac to find out what lies on the other side of the stone wall and locked gate, on which hangs a sign warning visitors to Keep Out!Topping the list of the ten most haunted places in America, Astaire Castle is associated with two suicides, three mysterious disappearances, and four murders since it was built almost a century ago-and Mac Faraday owns it! In spite of David's warning, Mac can't resist unlocking the gate to see the castle that supposedly hasn't seen a living soul since his late mother had ordered it closed up after the double homicide and disappearance of Damian Wagner, a world-famous master of horror novels. What starts out as a quick tour of a dusty old castle turns into another Mac Faraday adventure when Astaire Castle becomes the scene of even more murders. Mac is going to need to put all of his investigative talents to work to sort out this case that involves the strangest characters he has run into yet-including a wolf man. No, we're not talking about Gnarly.
