"Double Back" is Jon Allen's astonishing version of the classic "Dr. Daley's Last Trick." It is a highly visual and convincing two-card for two-card transposition that happens in the audience member's hands. After discovering "Double Back" I retired "Dr. Daley's..." for good. You will not believe the audience's strong reaction, which happens because they had JUST seen the two cards in your hands that suddenly appear in theirs.
Dean Dill (of blessed memory) said " 'Double Back' is my favorite packet trick of all time." It is definitely among my top five, and I use it all the time.
