The Shrieking Pit is one of Arthur Rees's earlier works, and is a good old fashioned murder mystery story. Grant Colwyn, a private detective, is holidaying in East Anglia when he notices a young man at a nearby table behaving peculiarly. The young man later leaves the hotel without paying his bill, and turns up in a nearby hamlet in the Norfolk marshes where he takes lodgings at the village inn. The next day, another guest at the inn is found dead, and the young man is missing. Can Colwyn sort out the mystery and prove the young man's innocence one way or the the other?
