"Diamond Bill" Barrett earned his nickname by sweet-talking a jewelry store into letting him borrow a $55,000 diamond, which he promptly hocked. Later, he deployed that legendary charm to sweet-talk two heiresses into marrying him, then disappeared with showgirl-turned-trophy-wife Sidi Wirt Spreckels' $100,000 string of pearls. But the mystery remains: Did he really steal Sidi's pearls ... or did he fence them for her?
