Christopher Pearson had big credentials. He was a Mashantucket Pequot Indian, grandson of the woman credited with holding the tribe together through its leanest period. He had a big dream, too. He would use his connection to the tribe to transform a tiny Caribbean island into the hemisphere's most attractive vacation destination. There would be more than 100 tropical acres of hotels, condominiums, time-share apartments, restaurants, marinas and cruise ship docks.
