Pittsburgh, Pennsylvania, 1948

When local wine king, Edwin McMasters, suspects one of his kids wants to kill him, he reaches out to Lacey Stocking, one half of the Hardley A. Witt Detective Agency, demanding their help. Not given the option of saying no, Lacey reluctantly takes the assignment.

Lacey and Hardley expect a quick meeting with their new client to discuss the matter. Instead, they're hauled off at gunpoint to the McMasters' family estate and forced to stay there while they uncover who wants dear old Dad dead.
