Readers of Ken Follett’s The Third Twin might be forgiven for thinking they’ve read this book before, since the plot is a mere amalgamation of standard genre elements: corrupt politicians, perverted scientific discoveries, and idealistic young whistle-blowers. The whistle-blower in this case is scientist Jeannie Ferrami, who has tackled the nature-versus- nurture question: She tracks down identical twins who have been raised separately and who have grown into, respectively, a criminal and a valuable member of society, and tries to figure out why. The corrupt politician is a senator who owns stock in a research company, Genetco, which is about to be sold for millions to a private investor. When Jeannie finds an identical twin who turns out not to be a twin at all but one of a series of cloned embryos implanted in unsuspecting mothers decades ago, the trail leads back to Genetco, provoking violence, bloodshed, and ever-escalating criminality. This is a great plane book: It will keep you distracted while aloft, but you won’t feel guilty about leaving it behind when you get off. B
