Riddle Me This, Einstein!

I noticed a book on a colleague's desk today called "Einstein's Riddle".  Well you just have to Google that, don't you.  Having found it, you then have to wonder at what you would have done so before ye olde internet was invented.  

Anyway, Einstein's riddle is: Who owns the fish?

The clues:

1. The British man lives in a red house.
2. The Swedish man keeps dogs as pets.
3. The Danish man drinks tea.
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.
8. The man living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The man who smokes Blends lives next to the one who keeps cats.
11. The man who keeps horses lives next to the man who smokes Dunhill.
12. The man who smokes Blue Master drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The Blends smoker lives next to the one who drinks water.

Of course, you could always Google the answer but where's the challenge in that?  And you never know; I might have changed it.
