Thirty boxes. Thirty body parts. Eighteen turned in to authorities.A forensic technician from a quiet Massachusetts suburb does the unthinkable: stalks a local woman, abducts her, divides her body into thirty pieces, and mails the sections to random Americans across the country. Each white postal box that Dennis Sweeney prepares contains an ambiguous note and a piece of Julie Piedmont. Most of the Sweeney's intended recipients contact the authorities about their gruesome packages, but twelve of the parcels go unreported. Pieces, the genre-bending hybrid of crime thriller infused with a short-story vibe, takes a closer look at the body parts that were never recovered and the possible reasons why their recipients never told anyone about their grotesque discoveries. Weaving the accounts together is Dennis' story as well as Jackson Matthews', the reporter to whom Dennis chooses to document his sick game.
