EFFECT :
Pack is shuffled freely by spectators and returned. Any
card is called for, magician places the pack in his pocket and
proceeds to spell out the name of the card asked for. The last card
he produces proves to be the correct card.


HOW IT'S DONE....
A duplicate pack of cards. This pack is divided into four
packets, one complete suit in each packet, the cards in each
packet running from A to K. These four packets are placed,
beforehand, one in each of four pockets, for instance, the two
outside coat pockets and the two trousers pockets. All you have to
do when a card is called for is to place the pack in the pocket in
which the corresponding suit of the duplicate pack lies. It is an
easy matter to find the required card from the pre-arranged set,
at the last letter of the spelling.
The placing of the pack in a pocket should be done as if from an
afterthought to make the trick even more difficult.
