Guy Lyon Playfair has produced an overwhelming body of evidence indicating that there is indeed a special connection between twins—much of it published here for the first time. Examples include: A man staggers and slumps into a chair clutching his chest at the exact moment that his twin brother—30 miles away—is shot dead  A four-year-old girl burns her hand while simultaneously her sister  suddenly develops a blister of the same size in exactly the same place. Playfair also makes a bold attempt to provide a new way of looking at the mystery of telepathy. Indeed, as he explains in clear, non-technical language, scientists may already have come close to solving the mystery of the twin collection—and telepathy in general—without realizing it.
