Steel Witches (Unabridged‪)‬

Tom Fletcher has left the police force, and its cold outside. Working as a P.I. in Cambridge, he is dragged back into his own troubled family history by an enigmatic message from his missing father.
Tom's inquiries begin to spiral into very darker conspiracies. How is an American company involved in an officially-suppressed story from World War II? Where is the US Air Force base that seems to be the key to a centuries-old mystery? And who were the haunting, haunted sisters who played such a part in a drama that is still reaching out to claim Tom Fletcher?
