One of my favorite book events of all time was one for Gerald Elias’ first Danial Jacobus mystery, Devil’s Trill (2009). Elias, himself a violinist (at the time associate concertmaster for the Utah Symphony), brought what he referred to as his “fiddle” to the event, and gifted the audience with a short performance. I’ve never forgotten it.
I was also a fan of the books, based on the odd-ish premise that a blind violinist could be a detective, his remaining senses sharpened by the lack of his eyesight, heightening his deductive reasoning abilities. This is actually pretty classic Sherlock Holmes territory, the “Watson” being Daniel’s former musical partner and friend Nathaniel. The mysteries, while utterly traditional, also gave the reader a bird’s eye view of the music world. Jacobus lives in seclusion in the New England countryside but is drawn out to the city for different reasons.
