L'Oreille cassée
Literary critic Tom McCarthy highlighted what he perceived as scenes in "Red Rackham's Treasure" which reflected common themes in "The Adventures of Tintin". He pointed out that in being a stowaway aboard the ship, Calculus was one of many stowaways in the series, and that the treasure represented the theme of jewels and precious stones which also cropped up in "The Broken Ear", "Tintin in the Congo", and "The Castafiore Emerald". He noted Tintin's misreading of the parchments and stated this was one of a number of calculation mistakes that the character makes in the series. He suggested that a scene in which the shark submarine pushes between Haddock's buttocks was a form of sexual innuendo referencing anal sex, highlighting similar innuendo in "The Broken Ear" and "The Crab with the Golden Claws".
