Insatiable Appetites by Stuart Woods

Insatiable Appetites is not as "fluffy" as some of the recent Stone Barrington books.
An old friend dies and Stone is in charge of handling his estate. A certifiably insane woman from his past pops back up. And Stone may be more serious about a woman in his life than he usually is. It will be interesting to see if the more introspective Stone is still around in the next book or if he goes back to his man-about-town, bon vivant ways.
