Summer is ending in County Cork, Ireland, and with it the tourist season. Expat Maura Donovan is determined to keep Sullivan's Pub in the black as the days grow shorter—but how? When she hears that the place was once a hot spot for Irish musicians who'd come play in the back room, she wonders if bringing back live music might be Sullivan's salvation.

As word gets out, legendary musicians begin to appear at the pub, and the first impromptu jam session brings in scores of music lovers. But things hit a sour note when Maura finds a dead musician in the back room the next morning. With a slew of potential suspects, it's going to take more than a pint and a good think to force a murderer to face the music.
