Edith has a document she prepared for Stanley Unwin regarding one of BR's activities and is sending it to Rotblat (not extant). She asks that he return it when he is finished. A handwritten note at the bottom reads: "P.S. My husband still knows nothing, of course, of this matter of the Nobel Prize." See the document, "Bertrand Russell's Work for Peace".

The letter is written on Plas Penrhyn stationary, but was sent from Hasker Street.
