Obtain a short "drawing-pin" with a small head, and having painted the
head black, stick it through the centre of the ace of clubs. Put this in
your pocket and "force" another ace upon a member of the company. Hand
the pack to the person upon whom you have forced the card, request him
to replace it and shuffle the pack. Then take the pack from him, and as
you turn your back slip the card with the pin through it on the top of
the pack. Holding the pack in your right hand with its face toward the
palm, ask your friend to name his card. When he does so throw the pack
sharply against the door. The top card will be held there by the pin and
the rest of the pack will fall on the floor.
This trick was shown by a conjurer before the late King Edward a few
years ago, and His Majesty was reported in the daily papers to have
expressed "great surprise."
