Lady Jane Pleydell-Bouverie
When Margaret (Macdonald) left us, she was replaced as Johnny's P.A. by Junior Commander Lady Jane Pleydell-Bouverie, the daughter of the Earl of Radnor, a quiet, pleasant, dark-haired girl, who remained with us until the end of the war.
Neither Margaret nor Jane made any contribution to our plans. But they were both efficient and undoubtedly served Johnny well.
