The Crab with the Golden Claws / Le crabe aux pinces d'or (1947)

Tintin is informed by the Thompsons of a case involving the ramblings of a drunken man, Kelber, later killed, found with a scrap of paper from what appears to be a tin of crab-meat with the word Karaboudjan scrawled on it. His subsequent investigation and the kidnapping of a Japanese man interested in talking to him leads Tintin to a ship also called the Karaboudjan.
