Los cigarros del faraón
Hergé himself helped to create two stage plays, collaborating with humourist Jacques Van Melkebeke. "Tintin in the Indies: The Mystery of the Blue Diamond" (1941) covers much of the second half of "Cigars of the Pharaoh" as Tintin attempts to rescue a stolen blue diamond. "Mr. Boullock's Disappearance" (1941–1942) has Tintin, Snowy, and Thomson and Thompson travel around the world and back to Brussels again to unmask an impostor trying to lay claim to a missing millionaire's fortune. The plays were performed at the Théâtre Royal des Galeries in Brussels. The scripts of the plays are unfortunately lost.
