The 13th by John Everson

Castle House Lodge. A century ago it was an exclusive resort hotel. But for years it's stood empty, a haunting shadow of its former glories. Now, after twenty-five years of rumors and ghost stories, the overgrown grounds are showing signs of being tended. The building itself has been repaired. Castle House has new occupants. What was once a haven for the elite is now a madhouse, a private asylum for pregnant women. But are all the patients really insane? And is it just a coincidence that people have begun to disappear from the nearby town? David Shale's girlfriend is one of the missing, and he's determined to find the truth behind the mysterious Dr. Rockford and his house of secrets. He will learn the meaning of the red X painted on the basement door...and he will know the ultimate fear, the horror of... THE 13TH.
