I recently read a great book by the name of "The Paris Apartment" by Michelle Gable. This book was an historical fiction book, based on a true story of a Paris apartment that was closed in the 1930s during World War II and not opened again until 2010. It was discovered after the owner Marthe de Florian died, left it to her child and that child died at 91 years of age. Then the estate discovered the apartment.
Below is the link to view the pictures and article regarding this wonderful apartment.

Michele Gable has another book, "I'll See You In Paris"coming in February 2016. It's about another of the paintings from the apartment. I won this book while participating in an online chat with the author and with my book club, The Book Chicks. This book is just as good, if not better than the first. Look for it in the book stores.
