This is the fifth book in the Regan Reilly Mysteries.
Los Angeles P.I. Regan Reilly is going to NY to attend a crime conference organized by her mother, famous author Nora Regan Reilly. She has a new beau, Jack "no relation" Reilly, who works in law enforcement in NY.
A family friend, Thomas Pilsner, president of the Settlers' Club on Gramercy Park, needs Regan's help in locating four missing diamonds, whose proceeds would have gone to the Club if only the two owners would not have died of unusual circumstances.
Carol Higgins Clark's writing style remains simple, but her plots are becoming less and less predictable - a good thing!
The novel involves a certain number of characters that are fun to read.
A nice little adventure that reads fast.
