Play a song for me… 

Musicians are being murdered in New Orleans, but Arnie Watson apparently died by his own hand. When Tyler Anderson plays the saxophone he inherited from Arnie, he believes he sees visions of his friend's life—and death. He becomes convinced Arnie was murdered and that the instrument had something to do with it, and with whatever's happening all over the city… 

Tyler knows his theory sounds crazy, so he approaches Danni Cafferty, hoping she and Michael Quinn will find out what the cops couldn't. Or wouldn't. After all, Cafferty and Quinn have become famous for solving unusual crimes. 

They're partners in their personal lives, too. Quinn's a private investigator and Danni works with him. When they look into the case, they discover a secret lover of Arnie's and a history of jealousies and old hatreds that leads them back to the band Arnie once played with—and Tyler plays with now. 

And they discover that, sometimes, the line between passion and obsession is hard to draw…
