Gathorne-Hardy wrote a biography of Gerald Brenan, The Interior Castle. He comments on BR's decision to name the Brenans as guardians of his children in case of his death. "It was, incidentally, a mad choice of the Russell's. Gerald and Gamel were both kind and conscientious but they were not good parents and any of their friends or relations who had children could see that at a glance. It reflects, I would say, the fact that Russell himself didn't really have any fundamental awareness of what was required in a parent, though he certainly had clear ideas of what he would like his children to become—in this case like Gerald and Gamel, and that certainly was a good choice."
