Hush now, don't you cry - Rhys Bowen

Match and despatch in one fell swoop.

Molly Murphy, now Molly Sullivan, and her new husband Daniel, a captain in the New York Police Department, have been invited to spend their honeymoon on the Rhode Island estate of Alderman Brian Hannan.
It's such a generous offer that Molly doesn't entirely trust it, especially as Hannan is an extraordinarily ambitious man and wants Daniel's advice on a private matter.

And then Hannan is found dead at the base of the cliffs overlooking the sea, even before he has had a chance to welcome them. Molly's suspicions are quickly justified and as much as she wants to keep her promise to Daniel that she won't do any more sleuthing now they are married, there isn't much she can do once the chase is on!
