The Magic Trail (La Piste Magique in the original French) is a comic story written by Patric Velli and Michel Motti, and drawn by Gino Esposito. It features Donald Duck, Scrooge McDuck, Huey, Dewey and Louie Duck, the Beagle Boys and Mister Mysterio.
Scrooge McDuck wants to learn a coin-multiplying magic trick for the stage-magc contest at the Billionaires Club, and Donald Duck and his nephews have seen a circus magician perform that exact number just the day before. Scrooge gets more and more stubborn on getting Mysterio to teach him the secret, and things get complicated when the Beagle Boys, utterly misunderstanding the situation, barge in to capture Mysterio whom they believe to be a real wizard.
