On May 20 of 1947, Christina Kettlewell was found deceased in Severn Falls, Ontario, her body lying in nine inches of river water. She was lying 150 feet away from a cottage where she and her new husband had been spending their honeymoon. The cottage had been burnt to the ground. When her death was investigated, a confusing tale was spun of insurance money, suicide letters, and even a possible love triangle.
