In another of those small-world coincidences, my dad knew about Teltec, which, he explained, was a PI firm—a company employing private investigators and skip tracers who tracked down the assets of business partners who’d squirreled away more than their share of the profits, men who were getting divorced and had tons of cash in hidden bank accounts, and so on. And, "I know Mark Kasden, the manager there," my father told me. Then he added, "How about if I give him a call? I bet he’ll want to know what you found out."
