Q157: Early clue

First I would like to say that is probably my lack of understanding english that made me think that the question in previous question was asking about the son, not the father. Thanks for giving me heads up anyway.

Now to the new question which probably will be quite easy. Where do we (as readers) get a clue to the culprit but Tintin probably doesn't in the very first frame?

Hi

I suggest a magpie in The Castafiore's Emerald (page 1).
Is it?

That was the one I was thinking of. Judging by frame 2 Tintin might perhaps be looking at the bird but most likely he's looking at Haddock.

Over to you Tuhatkauno.

Hello labrador road 26

my lack of understanding english

Worry not my western friend. Yesterday I took a glance over the previous questions and I have to confess that mostly I didn't have the faintest idea of what was going on. Now I can stop worrying that my question might be too difficult for this game.
