Garda Siobhán O'Sullivan's holiday plans hit a sour note when murder rearranges the yuletide carols into unexpected eulogies ... This December in Kilbane, if you're planning to warm up with a cuppa tea at Naomi's Bistro, you may have a bit of a wait--the entire O'Sullivan brood has gone off to West Cork to spend the holidays with brother James's fiancée Elise's family, including her grandfather, the famous orchestral conductor Enda Elliot. Siobhán is so happy for James and Elise but also quietly disappointed that she must put her own wedding to fellow garda Macdara Flannery on hold. Mac will have to join them later, so he can spend part of the holidays with his mam.

With the extended family--including Enda's much-younger new wife Leah, a virtuoso violinist--suspected in his murder, it's up to Siobhán to ensure the guilty party faces the music before the killer orchestrates another untimely demise...
