Aging media mogul Max Vanderhoven drives his vintage horse-drawn carriage up a mountain road and plunges off a cliff to his death. Was it careless driving? Suicide? Or murder! A second ambiguous fatality follows. Widow Dulcy McGuinness, attending a conference of horse and buggy aficionados, ferrets out the answers - and endangers herself - by unearthing clues connecting the construction of antique carriages to compositions by Mozart. Her interactions with her own horses, two grown sons and a new lover, plus intriguing and complex familial relationships among the other characters, all play out against old-world ambience vs. modern electronic technology.
