in James Swain's book "21st Century Card Magic" there is a trick called "I am in Debt" (page 108). While Fred Kaps is credited for the presentation, the method is said to be "changed considerably" by James Swain.
Does anybody know the original handling/Routine that was used by Fred Kaps or in which way it differs from Swain's version? Is it published?
Thanks and greetings from Germany,
