Who hasn't watched a TV talk show reuniting birth parents and the children they gave up for adoption or childhood sweethearts and thought, "How do the investigators hired by the shows find these people so easily, when the guests had been searching for them for years?" Wouldn't it be great to know how the investigators do it? People rush to go on those programs because hiring a P.I. can be extremely expensive; the cost per hour for a professional can run from $40 to $200 plus expenses—and specialists—polygraphers, handwriting experts, or fingerprints sleuths—charge even more. The Complete Idiot's Guide® to Private Investigating shows readers the many tricks of the trade that can be handled by anyone with the right information.
