Comments: Illustrated by Joseph K. Schmidt. “When deck is in the Interlock condition, one or more cards from the upper half are interlocked with one or more cards from lower half. This may seem a slender idea on which to base the content of an entire book, but one of the fascinating features of magic is a simple idea like this can indeed be exploited in ingenious ways by clever minds, to produce a variety of brilliant applications.”
