Publisher's Synopsis
A spanking-new tin can, secretly placed among the rows of Mrs. Florence Gentrie's preserves, contains not a speck of food - but it does carry one very damning clue to a murder that took place right next door. Such an unsavory discovery in such an unlikely place can't help but pique the curiosity of a dedicated mystery hunter like Perry Mason. But the real mystery about this murder is who - and where - is the victim? Upstairs neighbor Elston A. Karr heard the telltale sounds of foul play, but his foul temperament (and his own dark secrets) make him most uncooperative. It takes a second murder to clear up the mystery of the missing body - and to make Perry Mason the next prime candidate to disappear...
