The Duffie Diary
You begin by
shuffling a deck and placing it on the table. You never touch the
deck again. You now give the spectator your pocket diary which he
may examine before placing it in his pocket. You never touch the
The spectator will now create a random date. He cuts the deck –
this is a free cut – and turns over the card cut to. The value
of this card will represent the month. This can truly be any
value. He counts the cards that he cut – this will represent the
day. This can truly be any quantity so long as it doesn’t
exceed the number of possible days in a month. You can even offer
him the chance to change his mind and do it again. It will not make
any difference to the outcome. The trick cannot fail.
Maybe he cut to a Four spot – the fourth month is April. Maybe the
number of cards he cut is 15. That is APRIL 15th. The
spectator opens the diary at April 15 and reads out what is written
against that date. You explain that the diary will tell him about
his lucky card.
The diary might say, “21 DOWN!” But this is not a bizarre
crossword puzzle. The diary is telling him where to find his
LUCKY CARD. He counts to the 21st card in the deck. This card
may be the AS. Finally you ask him to look at the back of the diary
where he finds a card. Written on this card is “YOUR LUCKY CARD
IS THE ACE OF SPADES.”
