Monk's house is being fumigated, and he has nowhere to go. Fortunately, his assistant Natalie and her daughter are kind enough to welcome him into their home. Unfortunately, their home is not quite up to Monk's standards of cleanliness and order. But while Monk attempts to arrange his surroundings just so, something else needs to be put straight. The death of a dog at the local firehouse-on the same night as a fatal house fire-has led Monk into a puzzling mystery. And much to his horror, he's going to have to dig through a lot of dirt to find the answer.
