Diana also made an improbable friend of Kay Graham. They had met in the summer of 1994, when Lucia Flecha de Lima, wife of the Brazilian ambassador to the United States, took Diana to Graham's beachfront house, on Martha's Vineyard. Two years later, Kay gave a luncheon at her Washington home for Diana and Hillary Clinton. At a British Embassy lunch on the same visit, Diana became re-acquainted with Colin Powell. He told her he had been nominated to lead her in the dancing at the gala that night to raise money for the Nina Hyde Center for Breast Cancer Research. Scotland Yard had been worried that at a ball in Chicago earlier in the year a stranger had cut in on Diana's dancing partner. The general was deemed able to handle such an eventuality, but the Princess suggested she do a few practice spins with him in the embassy drawing room. "She was easy with any melody, and we did all right in our rehearsal," says Powell. "She told me, 'There's only one thing you ought to know. I'll be wearing a backless dress tonight. Can you cope with that?'" Flirting with the big boys—what bliss!
