truTV has an article on their site about Sir Harry Oakes:
In the early morning hours of July 8, 1943, a rainstorm raged on the small island of Nassau in the Bahamas. The rain pelted through the open window and doused the flames that engulfed the body of millionaire Sir Harry Oakes as he lay in his bed. Around 7 a.m. that morning, Sir Harry Oakes’ friend, Harold Christie, discovered his half-charred remains. His corpse had been saturated with gasoline, along with areas of his home, and set afire. A partially-burned lacquered Chinese screen near the bed was covered in blood and smudged handprints, wrote James Leasor in Who Killed Sir Harry Oakes? Feathers from Oakes’ pillow partially concealed his blackened, heat-blistered body. However, the feathers failed to obscure the congealed blood on his face and head, which led to Christie’s discovery of four small indentations on the left side of his skull. There was no doubt that generous and beloved self-made Harry Oakes was savagely murdered, but by whom?
It always amazes me when I read articles about Harry Oakes, and Niagara Falls is never mentioned!
