Author’s Note

      One of my most treasured possessions is a small cache of letters. Written in a looping, spidery hand with sentences that turn corners up the sides of pages before abruptly dipping overleaf, they are full of criticism and advice. The writer was a retired librarian and borrower of all my books but I never knew his or her name. Received over a four-year period, all of the letters were signed A Reader and no return address appeared at the top of the first of many pages. Not that there was room for one.

      Before I began work on this book, I took this unexpected advice and re-read Frenchman’s Creek. I was indeed enchanted once more. At the peak of her powers, du Maurier wrote about the Helford River mouth on the Cornish coast and the inlet that gave her novel its title. Almost cinematic in its imagery, the opening chapter is intensely atmospheric, a world of winds, tides and a silence broken only by the call of nightjars. Du Maurier moves seamlessly between Restoration England and the
