As usual,, I dont have the albums with me but is the answer Captain Haddock?
IN Prisoners of the Sun (dont have page number sorry), Haddock and the Thompson twins are both searching for Tintin. The Thompsons submit that one and a half persons should go one way and one and a half should go the other way. Captain Haddock puts them in their place by saying he will make his own way while they go in another direction.
Therefore Capitain Haddock thinks 1+2 is better than the 1.5 + 1.5 suggested by the Thompsons |
