Cigars of the Pharaoh
"Red Rackham's Treasure" was the second half of a two-part story arc which had begun with the previous adventure, "The Secret of the Unicorn". This arc was the first that Hergé had produced since "Cigars of the Pharaoh" and "The Blue Lotus" (1934–36). However, as Tintin expert Michael Farr related, whereas "Cigars of the Pharaoh" and "The Blue Lotus" had been largely "self-sufficient and self-contained", the connection between "The Secret of the Unicorn" and "Red Rackham's Treasure" is far closer.
