The Problem of the Trojan Hamburger

L.A. County, April 1985. Two crimes start separately, but merge a few days later. Multi-talented Hans Ballpeen is kidnapped for one of his special skills. Before they can bear down on this case, Kate and George must help with the delivery of an oak hamburger to the mansion of tycoon Orson Kane. Within a day, Kane reports that one of his prized possessions, the Despair Diamond, has been stolen.
