The plot went awry, however, and Mandraki was killed by the king's guard.
Constantine was succeeded by George II the same year.
Behind the scenes
The king of Greece first appeared in Rob MacGregor's novel Indiana Jones and the Peril at Delphi and its follow-up, and was not identified as Constantine by name until the release of West End Games' The World of Indiana Jones. As the novel takes place in October 1922, this creates an anachronism: the real life Constantine abdicated the month before in September 1922 and was in exile in Italy – which Peril at Delphi foreshadows – until his death four months later in 1923.
The timeline of Indiana Jones: The Ultimate Guide sets the assassination attempt in the May of 1922. However, it also places events from the novel out of sequence.
