Ben Jordan Case 3 ?

[Mr. Mozzarella]

I'm somehow stuck in Ben JOrdan 3, the Sorceress of Smailholm. I have been to the tower and had a look at the books. The McBees are gone and I can't go into the Crim's or the constable's house (do I have to do that at all?).
The only one I can talk to is Mary, but there are no options right now. The river and the forest are blocking my way.

What do I have to do next?

Thanks

Here is a link to a walkthrough, i'm not exactly sure all what you have done so far and there is two routes you can go so maybe the walkthrough will help
