 Using a dictionary, the gimmick is prepared by finding the first defined word on the left page, which is normally bolded or larger, and writing it in fine pencil on the top of the right page.The magician then holds the book open in front of the spectator and riffles with the left hand, and asks the spectator to call "stop" at any point.The magician then points to the upper right corner (blindly, as the book is still facing away from the magician) and while the spectator is looking there, peeks at the other corner, which is turned just enough to be visible.
