With overtones of Chasing Vermeer and The Borrowers, this inventive mystery involves two families that inhabit the same Manhattan apartment: the Pompadays-a slick, materialistic couple, their infant son and thoughtful James, from the wife's previous marriage-and a family of beetles, who live behind the kitchen sink and watch sympathetically as James's charms go unappreciated. Careful though the beetles are to stay hidden, boy beetle Marvin crosses the line, tempted by a pen-and-ink set James receives for his 11th birthday. Marvin draws an intricate picture and then identifies himself to a delighted James as the artist. Before James can hide Marvin's picture, Mrs. Pompaday loudly proclaims her son's talent and even James's laid-back artist dad compares the work with the drawings of Albrecht Durer. A trip to a Durer exhibit at the Metropolitan Museum of Art follows, James stowing Marvin in a pocket; before long a curator is asking James to forge a Durer miniature of Fortitude as part of an elaborate plan to catch an art thief (can a tiny virtue defeat big lies?).
