Paradox by Tony Corinda

A Spectator is asked to examine a pack of cards and to note that they are arranged in order, from ace to king, with suits rotating. The performer removes one card wich he seals in an envelope. Without knowing what card was removed, the spectator is invited to cut the pack anywhere and although he has a perfectly free choice, it is found that he exactly cut at the spot where a card is missing - The one sealed in the enveloped. This can be done with a borrowed deck of cards.
