Kirsten Lindquist has enough on her hands juggling the demands of her work as an orchestral music librarian. Substitute horn player Shay Bradley has been hitting on her for years, but Shay is known for being an operator, so Kirsten avoids her advances, until she can't resist. She is just beginning to get to know the new personnel manager, Stephanie Wellford, when the orchestra is shocked by the sudden deaths of three musicians and a string of suspicious accidents.

Kirsten, Shay, and Stephanie believe that the events are related, but they aren't certain how to prove it. Things get more complicated when Shay backs off to hide her depression and Stephanie admits her crush on Kirsten, but they need to stick together to figure out who is responsible for murder--before they become the next victims.
