What could be better for Agatha Christie whodunit fans than an old-fashioned, Scottish country house murder on New Year's Eve? Ringing in the New Year turns deadly at Rex's Hogmanay celebration. When barrister Rex Graves and his fiancée Helen d'Arcy host a New Year's Eve party at Gleneagle Lodge in the Scottish Highlands, an oncoming storm threatens to ruin the festivities. Despite the unlucky number of guests and an argument over the lost Jacobite gold, friends and colleagues alike are enjoying the evening with drinks flowing freely. But as the clock strikes midnight and the power goes out, Ken and Catriona Fraser -- the inheritors of Gleneagle Castle -- are found dead. Suspecting the Frasers were murdered for monetary gain or revenge, Rex investigates who and what killed the couple. He must use his skills of intellect and detection to catch the culprit in this traditional locked-room mystery.
