Sarah Morris Remembers more--a wee guid bit more, this time dealing with the years of her marriage to Charles Reede starting out in their new cottage where Charles will write down his ""rainbow dream"" in a book. Sarah edits it secretly and it will be published by the close of this one. In between, the holiday visits of her niece, Freddy, unloved and mismanaged by her petulant mother; visits with neighbors and villagers, with the reclusive Sir Rupert, and nearby at Sarah's grandparents' who will leave her the big house to replace the cottage. . . . Och aye for that friendly readership and oh ecccch for anybody else.
