Comic review - Tintin #13 - "The Seven Crystal Balls" by Herge

There had been two other two part Tintin's before, but this is the first one that was very much a Part 1, i.e. it doesn't really stand on its own. It gets off to a strong start, with creepy illnesses striking survivors of a Inca expedition, and mysterious balls of fire, but the last third or so is just running around looking for Calculus, and since you know we won't find him because you need him gone for the sequel, it feels all kind of pointless. It's done with pace, speed and accomplishment but I wouldn't count it in the first rank of Tintins. He's not living at Marlinspike at this stage, incidentally - Haddock is shacked up with Calculus.
