We've all had the fantasy of being able to know what is inside the private diaries, letters, or yes, address books of celebrities. Brigitte Benkemoun's husband bought a replacement Hermes agenda on Ebay ( I happen to know these very well, I still have a desk black one with my initials and a small pocket red one similar to the one her husband was looking for though mine are consigned to a file cabinet now when I cruelly abandoned them first for Filofax and then the Contacts section of my iPhone). When it arrived, she was overwhelmed to discover the names of very famous French artists, poets and writers of the 20th century like Balthus, Brassai, Breton, Cocteau, Eluard--along with a plumber and architect and a hairdresser. It did not take her long to learn it was the agenda of none other than Dora Maar, known principally as the Weeping Woman model for Picasso and his lover for many years who was devastated when he abandoned her for Francoise Gilot (and others) and became a religious recluse in Mesnerbes, Provence. Benkemoun imagines the relationship Maar might have had with each entry, often importing her own conclusions when facts do not present themselves, but it is still a very engaging and often moving promenade down memory lane.  The book has been published by the Getty, where the retrospective of Maar's important work as a photographer and artist was shown, exhumed first at the Pompidou. I had my own chase of Dora Maar and treasure her letters to me.
