Length: 6 hours and 32 minutes
Description: 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 realizes 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?
My Thoughts: The third Mercy McCarthy mystery has Mercy, her sister Lizzie, and lots of their neighbors from the court spending the weekend at Inishmore Castle. The owners of the castle are planning to open it to visitors and also make their whisky brand more popular.

Among the other guests are a priest and a nun. Mercy is suspicious of them as they don't act like any other priests and nuns she has met. She finds them arguing on a couple of occasions despite their claims that they don't know each other.
When Mercy discovers the body of the priest in the study, Mercy wants to call Kieran - after she does a bit of investigating herself, but a storm has knocked out cell phone service and flooding has made the bridge to the castle impossible. She discovers identification in the priest's wallet bearing another name and convincing her that something odd is going on.
A break in the storm allows Kieran and his crew to arrive. The two begin to investigate with Kieran reluctantly allowing Mercy to participate. There are rumors of a lost treasure hidden in the castle which might account for the priest in disguise.
When the nun, who also turns out to be fake, is also murdered by strangulation and disposal in the pond, the crime gets more complex. Mercy had been looking at her as the prime suspect. There are other things going on and other suspicious guests. The young birdwatcher is not talking about her past. The accountant is most notable to Mercy for his shifty eyes. And the rich couple from Tennessee who are eager to distribute the local whisky includes a kleptomaniac wife.
Untangling all the characters and finding the treasure keeps Mercy and Kieran busy and the real killer is still to be caught.
This was another entertaining cozy. Mercy is overly curious and impulsive but has a good heart. Keeping her safe looks to be Kieran's new goal in life.
