Festive lights and holiday displays are popping up all over the Scottish Highlands city of Inverness. Over on Church Street, Rev. Daniel Darrow is busy trying to rein in the kirk's longstanding nativity display feud with the Old High Church up the road. All he wants for Christmas is more time with the bonny Ellie Gray who is home on break from university. But when the sudden arrival of his prodigal flatmate coincides with the body of a beloved parishioner washing up on the shores of Loch Ness, Daniel's hopes for a calm, cozy season become as elusive as the loch's famous monster. Now Daniel and Ellie must race to discover the true killer before the police lock away the wrong man or anyone else at Church Street becomes the next victim.
