Annabelle Shannon returns to her ancestral homeland of Ireland and is eager to take in the sights and sounds, but more importantly, spend time with her grams at their family’s historic Gladstone Castle.
Soon after arriving to the sprawling home, situated in the outskirts of a quaint village, her grams delivers some exciting news: she’s planning to retire. Not only that, she offers for Annabelle to take over her position as a castle tour guide. In order to determine if Annabelle is truly interested, Grams invites her along to spend the night at a newly-restored thirteenth-century castle before it is set to open as a hotel.
But not long after settling in for the night at the castle hotel, one of the elderly guests is found face down on the floor, motionless, in one of the opulent quarters. The death is quickly deemed to be of natural causes, but Annabelle has her doubts…
Will the person responsible be apprehended before another victim is claimed?
