The Barnstable Curse by Vincent R. Vurchio

The exploits of Dr. Felix Tanner, JJ Burgoshofski, and Glenna D'Angelo, as begun in "The Harloc Mirror", continue in "The Barnstable Curse", as the trio of supernatural investigators struggle to unravel the disappearance of a young woman -- the possible victim of a centuries-old spell -- while wrestling with demons from their own pasts.
