Irish whiskey, rolling green hills, a traditional Christmas feast and... a murder? Lady Swift will need the luck of the Irish to survive this holiday season! Christmas, 1924. Lady Eleanor Swift has received a rather unexpected invitation to the village Christmas party in the tiny, rural hamlet of Derrydee in the west of Ireland. Eleanor is thrilled about exploring her ancestral roots at her late uncle's estate and spending the festive season in a castle. Packing Gladstone the bulldog's coziest Christmas jumper, they set off to the Emerald Isle with her butler Clifford in tow. Arriving late at night, Eleanor and Clifford are shocked when they find a body sprawled in the snow on the winding country lane outside the estate. The local constable is immediately suspicious and all but accuses the pair of murder. This isn't the warm Irish welcome Eleanor imagined! Clifford is certain he recognises the poor fellow from the funeral of Eleanor's uncle - but what was their connection? Undeterred by the villagers' lack of gossip on the matter, Eleanor is determined to get justice for the victim. The man's pockets are suspiciously empty of personal effects, but closer inspection reveals an old key hidden in the heel of his boot. Could this unlock more than one mystery for Eleanor? But when a fire breaks out at the castle on Christmas Eve, an even bigger question looms: is someone out to ensure the family line dies with Lady Swift? And will Eleanor's first Irish Christmas be her last?
