This was a terrific tale til the terrible ending. Ruby "drowned" but had a crushed skull. possibly when her hair was caught in a boat propeller. I thought this would be the clincher for murder. If she had drowned as the cause of death, the propeller injury would have occurred after she drowned a there would have been no bleeding in the brain. If there was bleeding in the brain, then she was murdered. Why no final autopsy results????????????? Poor ending!
