Eventually, Valentine and her husband were released from Romanian detention in 1958, and allowed passage to Britain, where Marthe, now totally dependent on her writing for money, bought them a home, the Tullimaar residence at Perranarworthal in Cornwall. She remained in Paris, first living at the Ritz Hotel (1946–1948), then in her apartment at 45, Quai de Bourbon. In 1955, she was appointed a member of the Belgian Academy of French Language and Literature, on the seat previously held by Anna de Noailles (née Bibesco, princess Bassaraba de Brancovan). Marthe cherished the 1962 award of the Légion d'honneur. It was in 1960 that her novel (27 years-in-the-making), "La Nymphe Europe", which was really her autobiography, was published by Plon.
