This was our hottest day so far. I began a rough preliminary sketch of my new film and I did about a third of it in the morning before a bathe. We bathed with Diana Cooper, Lady Horner, who had her two grand-daughters, Lady Helen and Lady Perdita Asquith with her, and the boy, Lord Oxford.
I talked to the old lady while on the raft. The Diana-Horner party went off to lunch at Talloires.
Duff Cooper had arrived in the early afternoon from Geneva.
He and Diana were returning from a rowing excursion (and reading Wells's new novel aloud to one another on the lake) just as Dorothy and I were finishing tea on the terrace.
