Einstein's problem

Here is a problem set by Einstein. He estimated that only 2 % of the general population would be able to work this out, but actually it is more a matter of persistence than great genius. Give your brain some candy this Christmas and have a go!

5 men of different nationalities live in 5 houses of different colours. They smoke 5 different brands of cigarettes, drink 5 different drinks and keep 5 different types of animals. The question is: who keeps fish?

Here are the clues:

1. The Norwegian lives in the first house
2. The Englishman lives in the red house
3. The green house is to the left of the white house
4. The Dane drinks tea
5. The man who smokes Rothmans lives next to the one who keeps cats
6. The man in the yellow house smokes Dunhills
7. The German smokes Marlboroughs
8. The man in the middle house drinks milk
9. The Rothman-smoker has a neighbour who drinks water
10. The Pall Mall smoker keeps birds
11. The Swede keeps dogs
12. The Norwegian lives next to the blue house
13. The man who keeps horses lives next to the yellow house
14. The man who smokes Philip Morris drinks beer
15. Coffee is the drink in the green house
