She hit him over the forehead with her spike-heeled shoe, then hit him several more times and ran out. But after all of Siegel's work and worry, the Flamingo finally seemed to be making money. Siegel apologized to Virginia and invited her to take a trip to Paris. In mid-June, Meter Lansky himself arrived at the Flamingo to spend a few days. There were some meetings.
Nobody really knows what happened.
According to Doc Stacher's version, which is presumably Lansky's own version, Lansky did his best to defend Siegel to the end. Other speculations suggest that Lansky himself decided Siegel must be punished, that his last trip to Las Vegas was his version of the kiss of death. Siegel seemed to have no premonitions about what would happen. He spent his last few days on various secret meetings and negotiations, but he showed no particular sign of anxiety. He flew to Los Angeles just after midnight on June 20 and let himself into Virginia Hill's house with a golden key that she had given him.
