Gladstone's Terrible Secret, also printed as The Good Luck Charm, is a comic story written and drawn by Carl Barks. It features Donald Duck, Huey, Dewey and Louie Duck, Gladstone Gander, Scrooge McDuck, and, in his debut, Gyro Gearloose.

All their "tests" deliver a negative answer to the first question, but as to the second, they figure out that the answer might lie within an iron strongbox Gladstone keeps in his house…
