Five houses painted five different colours stand in a row. One person of a different nationality lives in each house. The five home owners all drink some type of beverage, smoke a certain cigar brand, and have a certain kind of pet. But none of the owners drink the same beverage, smoke the same type of cigar, or have the same pet.

And here are the clues:

1. The Brit lives in the red house.

2. The Swede keeps dogs as pets.

3. The Dane drinks tea.

4. The green house is on the immediate left of the white house.

5. The green house’s owner drinks coffee.

6. The owner who smokes Pall Mall rears birds.

7. The owner of the yellow house smokes Dunhill.

8. The owner living in the center house drinks milk.

9. The Norwegian lives in the first house.

10. The owner who smokes Blends lives next to the one who keeps cats.

11. The owner who keeps the horse lives next to the one who smokes Dunhill.

12. The owner who smokes Bluemasters drinks beer.

13. The German smokes Prince.

14. The Norwegian lives next to the blue house.

15. The owner who smokes Blends lives next to the one who drinks water.

The question is: Who owns the fish?
