Changes from the Book
Mitsuhirato's assistant, Mr. Lee, is shown to be a double agent in the service of the Sons of the Dragon, and it is he who replaces the Rajaijah Juice with a harmless substitute and delivers the real poison to his employer Wang Chen-Yee. In the book, this was done by another agent. Gibbons is not shown at all, and Dawson's role is much reduced, he is only shown as the police commissioner who calls in Thompson and Thomson, and does not appear to be in league with Mitsuhirato.
This is to create a subsequent continuity error in The Red Sea Sharks (TV episode), as Tintin mentions having a "run-in" with Dawson despite not encountering him in this adaptation of the story. At the end of the story, Roberto Rastapopoulos tries to flee through the Blue Lotus club when the other villains are apprehended, but is himself caught by Thompson and Thomson. In the book, Rastapopoulos was apprehended along with Mitsuhirato. Also, this episode, unlike the book, doesn't reveal Mitsuhirato's fate.
