Please keep in mind that this is only the instructional manuscript and does not include the three specially printed books that are part of this effect. However, the instructions will explain you how the trick worked.

Al Mann writes in the foreword: “Codex-X is the final-port-of-call of an odyssey that has taken the author through many years of study and planning. Codex-X was primarily inspired by the late Richard Himber’s many book tests and C.L. Boarde’s monumental work Mainly Mental Vol. II on book tests. It was secondarily inspired by the mentalist’s love for the mystery of the book test that was popularized by Annemann in his Jinx and by Burling Hull in his writings.”
