Siegel's trouble with the Flamingo began when, a year after its official groundbreaking, the resort had produced no revenue and drained the resources of its mob investors. Then Meyer Lansky charged – at a major mob conference in Cuba – that either Siegel or Hill was skimming from the resort's building budget. This charge was amplified at a time when Hill was revealed to have taken $2.5 million and had gone to Switzerland, where the skimmed money was believed to be going.
