The Tossed-out Deck isn't it more subtle ?
Working from the reprinted version of the 1937 Sharpe translation:
On page 53 there's an item where you have a card selected, the pack is shuffled and then dealt or spread into a circle in the center of which you place a pointer. The pointer is set to spin and winds up pointing to their selection. The method is as noted ealier a straightforward use of the forcing pack with one extra odd card at the bottom for them to notice. There is no mention of tying up the pack nor of having a selection peeked - which is taught though as a force a few items earlier on pp47-48 in the item starting on page 47.
I did not notice another mention of this sort of methodology in the book in today's quick rummage.
