Richard Coulter is a man who has everything. His beautiful new wife is pregnant, his upstart airline is undercutting the competition and moving from strength to strength, his diversification into the casino business in Macau has been successful, and his fabulous Art Deco house on an Irish cliff top has just been featured in Architectural Digest. But then, for some reason, his ex-wife Rachel doesn't keep her side of the custody agreement and vanishes off the face of the earth with Richard's two daughters. Richard hires Killian, a formidable ex-enforcer for the IRA, to track her down before Rachel, a recovering drug addict, harms herself or the girls. As Killian follows Rachel's trail, he begins to see that there is a lot more to this case than first meets the eye and that a thirty-year-old secret is going to put all of them in terrible danger.
