....is Mathilde Belard, who as Madame Carre, was a double agent during World War II. Her story, by the Paris correspondent of the English who has checked sources, tells of her marriage, her connection with the Polish ""Armand"", and their work with Inter-Allied espionage, and then her collaboration with the Germans which led to the betrayal of resistance workers. Known as The Cat, she was installed by the Germans at The Cattery and continued her career under their instructions. Sent to London, she was under surveillance, finally arrested and imprisoned, and, back in France, tried for treason. Her sentence of death was commuted to life imprisonment, and in 1954 she was released. A poser for those whose interest is espionage, for the verdict remains hung as to her full innocence or guilt, and this examines the evidence with care.
