In an unpublished article that Sir Joseph wrote many years ago, he wrote:

Having become more and more disillusioned and unhappy about the work that I was doing, it was a great relaxation to talk to someone who had nothing to do with the project . . . She was very much interested in literature and the arts, and I learned a good deal from her. Naturally, we talked about politics and discussed the progress of the war. We also touched on my personal matters [i.e. his wife and plans to return to Poland] . . . we never talked about the atom bomb project.

He suspected that these conversations were overheard and later repeated

in an unbelievingly distorted manner, by an agent, probably the Hispanic janitor, who hardly knew English and made up with his imagination what he did not understand.
