Just got to page 9 but bursting to join in on this!
1 The boots - did you notice that Morten had new shoes in the first episode (I think)? Why have they done nothing about the boots? They looked unusual and it would be relatively easy to find out where they came from and probably who paid for them.
2 The library books - why did she return them to her teacher at midnight?
3 The girl's bike - the police said they'd found her bike at the teacher's house. We weren't shown that (were we?) Why would she leave the bike there?
4 I think there's a group of sexual predators (who are not necessarily linked to the murder.) I think they are going to Latvia for sex - probably underage. Don't forget the victim was a schoolgirl. I think the mayor, the leader of the coalition (with greasy hair), the mayor's press adviser and probably (a hunch here) the new police chief were involved in it.
5 I don't think that the perpetrator is going to be new on the scene now.
6 Troells is gorgeous. It's hard to believe there were no rumours about him being on that site.
7 I'd forgotten about the girl running through the woods - thanks, whoever reminded me - even though it's on every episode! How, then, could she have died in the flat? Was she running, then caught, then taken to the flat? Wouldn't attention have been drawn to her then?
Gah! I love this programme! It's the best since Wallander, and far better because of the tension. And knowing the answer is on Wikipedia just TORMENTING me doesn't help!
