Susan Chitty suggests that BR slept with Antonia after a Monday evening lecture on Kant in 1928, even though Antonia insisted that she never slept with BR. The letter BR sent to Antonia is found in Susan Chitty's Now to my Mother, a memoir of Antonia White, page 28.

"I was quite intoxicated by your kindness to me yesterday, and have been wondering ever since what I had done to earn it ... I keep wondering whether it was just a mood, or whether you feel the same way still ... I find that I can be free on Monday—after all ... will you stay with me 'til morning? Or is that asking too much? And if it is, what is the most you will concede? ... You know how much I have wanted you and now hope makes me dumb and shy."
