Private investigator
The novel begins with backstage performance jitters just before a musical performance at Carnegie Hall in New York to be given by a striking young violinist, Jan Tusar and his on-again-off-again girlfriend and piano accompanist, whose father has died a few months earlier in a fall from his office window. Private investigator Tecumseh Fox is by no means a follower of classical music, but has been convinced by his friend Diego Zorilla, a former violinist whose fingers were mangled in an accident, to charitably contribute to buying a valuable violin for the young performer.
