Presented with a page like this, obviously I sat down to solve the puzzle. :) For others who do the same, CRUCIAL CLARIFICATION: The constraint that "The green house is on the left of the white house" must be read as saying that the green house is immediately to the left of the white house, not merely that it is somewhere to the left (otherwise you don't have quite enough information to continue). It's a really well-constructed puzzle, though: the identity of the fish owner is the very last part of the grid that you get to fill in.
