Blach refers to a forthcoming visit and William's sudden call to go to England:

"William <Clark?> phoned a short while ago. He was in an tremendous rush, informing me that he had precisely half an hour in New York, that he wanted me to let you know that he had suddenly been called to England, that he had been unable to let you know, because it all happened so quickly, that he can be reached at the Ministry of Information in London, that he will be back in this country in September."
