Everyone on Willow Street seems to have a bone to pick with their eccentric new neighbor, Zeno. An "interactive environmental artist", his idea of art seems to involve large piles of rusting junk and thunderous noise. Then Zeno's estranged wife is found murdered in his house. Odd though it might be, Claire Molloy, devoted amateur sleuth and bookstore owner, doesn't believe Zeno is a murderer. But if Zeno didn't do it, who did?
