Einstein's Riddle: Who owns the fish?


The following riddle was supposedly posed by Albert Einstein (I haven't been able to verify that), he reportedly claimed that less than 2 percent of the people in the world could solve it.

There are 5 houses in 5 different colors. In each house lives a person with a different nationality. The 5 owners each drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain type of pet. No owners have the same pet, smoke the same brand of cigar or drink the same beverage.

The following statements are all true:

  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 immediately to the left of the white house.
  5. The green house's owner drinks coffee.
  6. The person who smokes Pall Mall rears birds.
  7. The owner of yellow house smokes Dunhills.
  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 one who smokes Dunhills.
  12. The owner who smokes Bluemasters drinks beer.
  13. The German smokes Prince.
  14. The Norwegian lives next to the blue house.
  15. The man who smokes Blends has a neighbor who drinks water.

The question is: "Who owns the fish?"

Believe it or not, there is sufficient information in the list of statements to settle this question.

A hint.
