McCarren's Rules ~ Angel Falls

Private investigator Julianne McCarren would give anything to have her husband alive again but settles for the occasional comment he makes in her head. His wedding gift to her, a blue diamond necklace named Angel Falls, goes missing from her safety deposit box in New York, with only a replica in its place. Aided by Security Specialist Macklin Pierce and her niece, Julianne sorts through obsessed in-laws, a grieving bank vault escort, a scheming mistress, and a threatening gang member, all with Russian ties. Who made the replica, why was a bicycle messenger killed, and will Julianne recover her necklace before it's lost forever?
