A grand castle, a glass of Irish whiskey, a good book by the fire… and a rather mysterious murder?
Historic Inishmore Castle is opening its doors for the first time, hosting a charming weekend of whiskey tasting and soda bread baking. Sisters Mercy and Lizzie McCarthy are badly in need of a break, but their relaxing trip takes a decidedly unrestful turn when Mercy finds fellow guest Father Brennen slumped over the desk in the library… Did he have one glass too many or did someone want him dead?
Even more curiously, Mercy swiftly learns that the priest was no priest at all. So why was he searching through dusty old journals? Can the legend of Inishmore’s lost treasure possibly be true?
Mercy’s suspicions of foul play are confirmed when another of their party is found drowned in the lake at the edge of the manor’s estate. It can’t be a coincidence! Someone in this idyllic Irish castle is up to no good and Mercy is determined to find out who’s behind it, accompanied by her reluctant fellow sleuth and beloved dog Mr. Poe.
With a host of frightened guests and worried staff, and a storm closing in, Mercy soon has more suspects than bedrooms in the castle. Could it be the unconvincing nun, the busybody birdwatcher, or are the owners hiding something sinister? When Mercy realises there are secret passages in the walls, she thinks she might have cracked the case… but will she track the killer down, or will Inishmore be her resting place forever more?
