Their marriage, which produced four daughters, was not a happy one. Ms. Garnett eventually deduced the relationship between her husband and her birth father, realizing that Garnett had married her as a way of maintaining a hold over Grant, whom he still loved, and Vanessa, whom he had tried to seduce only to be rebuffed. Ms. Garnett left her husband after more than a quarter-century of marriage. Vanessa Bell died in 1961; after Grant's death in 1978, Ms. Garnett, her children grown and gone, looked in the mirror and saw, as she wrote, "a vagueness, almost a hole, where I myself should have been." She began her memoir, she wrote, "to describe my own ghosts, and, in doing so, to exorcise them." Her other books include a volume of autobiographical fiction, "The Unspoken Truth" (2010). Two of Ms. Garnett's four daughters died before her. "My eldest daughter, Amaryllis, who was very beautiful and deeply intelligent, drowned in the Thames when she was 26; I think it was suicide," Ms. Garnett said in an interview quoted in her obituary in The Telegraph, the British newspaper. Henrietta, my second, married when she was 17, and her husband died less than a year later. Then she tried to commit suicide when she was 25 by jumping out of a window. She was broken from top to bottom and has remained fragile ever since. A third daughter, Nerissa, died of a brain tumor in 2004. Besides Henrietta, Ms. Garnett is survived by another daughter, Frances, who was "described by her mother as "a kind of mystic," " The Telegraph reported. In interviews after her memoir appeared, Ms. Garnett spoke of having taken pains to ensure that the legacy of Bloomsbury was not visited on the next generation. "Everyone has a certain difficulty in growing up, even my children, although I've been a good mother," she told The Australian Financial Review in 2010. I'm still not grown up in some ways compared with other people I know.
