Dogged by internal dissension and by a potentially devastating lawsuit from its fired second violinist, the famed New Magini String Quartet is on the brink of professional and personal collapse. The quartet pins its hopes on a multi-media Carnegie Hall performance of Franz Schubert's masterpiece, "Death and the Maiden," to resurrect its faltering fortunes. But as the fateful downbeat approaches, a la Agatha Christie, one by one the quartet's musicians mysteriously vanish, including second violinist, Yumi Shinagawa, former student of renowned blind pedagogue and amateur sleuth, Daniel Jacobus. It is left up to the begrudging Jacobus, with his old friend, Nathaniel Williams, and a new member of the detective team, Trotsky the bulldog, to unravel the deadly puzzle. As usual, it ends up more than Jacobus bargained for.
