Everyone goes to Finnegan's....
It's a pub in lower Manhattan, run by the Finnegan family for generations and now owned by Kieran and her three brothers. Kieran Finnegan, who still works there whenever she can, has become a criminal psychologist - a fitting reaction, perhaps, to her less-than-lawful past.
Meanwhile, New York's Diamond District has been hit by a rash of thefts. No one's been killed - until now. FBI agent Craig Frasier is brought in to investigate; he and Kieran meet at a jewelry store in the middle of a heist. She's there to "unsteal" a flawless stone taken by her light-fingered youngest brother as an act of vengeance. He's there to stop the gang.
But the police and FBI soon discover that there are two gangs of diamond thieves, the original and a copycat group of killers. And the second group seems to think their scheme is as flawless as the stones they steal.
Thrown together by circumstance, drawn together by attraction, Kieran and Craig both end up working on the case. Unfortunately, there's more and more evidence that, somehow, the pub is involved. Because everyone goes to Finnegan's....
