This episode ruined a great winning streak for me and this season of Superman. A dead man, who turns out not to be dead left a million dollars in diamonds on a deserted island for four of his cousins to search for and the one who finds them keeps the diamonds in its millions. The man turned out not to be dead and was on the island waiting for Perry, Lois, Jimmy, Clark and the cousins to find him and the loot. One did find them and one of them tried to kill the others for the value. He was discovered by Clark and is probably at this time in the 50s, in prison. It was a good plot but the island theme has gotten old. I hated it.
