By then I’d called every Dukes in the Manhattan book, and every Duke, too; there weren’t all that many of either, and it seemed reasonable that one of them might be related to Frankie Dukes, or at least know of him. But plural or singular, nobody could help me out. Then I got home from St. Paul’s one night and there was a message to call Mr. Bell. I dialed the number on the slip and they answered at the Top Knot and called Danny Boy to the phone. “You could stop by,” he said, “and I was going to suggest that, but it’s easier to pass this on over the phone. Unless you feel the need to compare the Top Knot’s Coca-Cola with Poogan’s, in which case I’d welcome your company.” I told him I was just about ready to call it a night. “Then write this down, Matthew. Francis Paul Doo-kosh, except that’s not how it’s spelled.” He spelled it out for me. “It’s Hungarian, I think, or maybe Czech. One of those countries that get in the papers whenever the Russians send in their tanks.”
