I don't think that there's any good evidence that Tintin was being “controlled” by Haddock or the Thom(p)sons either.
And I thought I'd pick up on a few niggly points...
Allan already knows of Tintin before he even appears on the docks with Terry (he tries to kill him by dropping boxes on him). How does he know of Tintin and how dangerous he can be? He has never met Tintin before, yet he plans to kill him. Allan appeared in Cigars of the Pharaoh but didn't meet Tintin at all in it.
One reason could be that the Japanese police detective, Bunji Kuraki, was kidnapped by the opium gang whilst trying to deliver a letter to Tintin to warn him about them. As Tintin didn't recieve this letter we can assume that the gang read it and so became aware of Tintin. And Tintin himself was already very famous (discussed in this thread How famous is Tintin ?
) esp. if we think back to his previous adventures where his name had appeared in the newspapers or he was given a hero's welcome like in Soviets
And although Allan appears in the colour version of Cigars
(which was made in 1955, i.e. after Crab
) it was a completely different character in the original 1932 b/w version.
Based on weak evidence Tintin convinces the police in Callao to search the whole ship of Pachacamac. This must be after orders from the Thom/p/sons or Haddock.
Don't forget at the beginning of Prisoners
that the Chief Inspector at Callao mentions that Interpol had warned him they were coming so there was probably some international pressure on them to help with the case! (And although Tintin and Haddock don't present their evidence I'd say it was fairly
good with Calculus' hat having being found when and where it was.)
After jumping off the sabotaged train Tintin and Terry meet a man on a trolley. The man identifies himself as "the stationleader" of the next station, but why is he coming from the wrong direction then? He is clearly informed of this accident by someone from the police.
I'm not sure why you think it's the wrong direction. Perhaps you're not realising that the coach which becomes loose rolls back in the opposite
direction to the way it was originally travelling?
