While teaching a master class at an elite music conservatory, blind violinist and amateur sleuth Daniel Jacobus gives an extra lesson in how to catch a killer. When reclusive, blind violin pedagogue Daniel Jacobus is invited to speak at a seemingly innocuous symposium on Baroque music at a prestigious music conservatory, he has no idea he is about to become enmeshed in an entrenched culture of sexual harassment and its cover-up at the highest levels. And when a renowned faculty member dies of apparent natural causes, only the curious behaviour of a violin student at Jacobus's master class is an indication to him that something may be terribly amiss.
