The Black Island
Literary critic Tom McCarthy thought that "The Black Island" linked to Hergé's other "Adventures" in various ways; he connected the counterfeit money in the story to the counterfeit idol in "The Broken Ear" and the fake bunker in "Tintin in the Land of the Soviets". He also connected Tintin's solving of the puzzle in the airman's jacket to his solving of the pirate puzzles in "The Secret of the Unicorn", and that in transmitting from a place of death, Ben Mor, or "mort" (death), it linked to Tintin's transmitting from the crypt of Marlinspike Hall in "The Secret of the Unicorn".
