New friends tell them of a famous Ravenslake mystery-the vanishing of student John Traynor. He disappeared, without a trace, into the midnight darkness of a nearby hamlet forty-one years ago. Most believe he was murdered, but no body or killer was found. Students believe Traynor's ghost haunts the site of his old dormitory. Others believe Traynor suffered an accidental head injury and amnesia, wandered to a distant location, and gradually assumed a new identity without any awareness of his life as John Traynor.

And other skullduggery is afoot In a genteel college town setting, Mac and Jen must apply their famous curiosity and initiative to disentangle the web of mysteries at Ravenslake University.
