Qwill's on top of the world when he rents a house on Big Potato Mountain from its owner, J.J. Hawkinfield, the man who brought real estate development to the once-peaceful Potatoes. But this particular entrepreneur paid a steep price - he was pushed off a cliff by an angry mountain dweller. Qwilleran, however, suspects the man is innocent—and Koko's antics have him convinced something's wrong. He may be making a mountain out of a molehill...but he's determined to find the truth. Even if it means jumping out of the frying pan and into the fire!
