A Rather Lovely Inheritance by C.A. Belmond (2007)

 A pleasant book about New Yorker Penny Nichols, a historical researcher (my kind of person) for movies finds out she has inherited something from her Aunt Penelope - an apartment in London and a garage with its contents next to a villa in southern France. But she has to do quite a bit of research to figure out what she really has inherited. She is helped along by cousin Jeremy, a lawyer, with whom she got along with quite well in a childhood summer holiday. Looks like they are still getting along... Of course they have the nasty ne'er do wells in the family who want to take away their inheritances, but it all works out in the end. Lovely romp through England, France and Italy.

Looks like there are more of these "Rather" books and it looks like they will continue with Penny and Jeremy, so I have another series to look forward to.
