My Mother and the Nazi spy?

My Mother and the Nazi spy? During the war in Louisbourg my Mother Celia LeDrew (nee Shaw) ran a boarding house from Grandfather's house on commercial St right on the water near the government wharf and across from Cann's marine yard. Mother had a couple of boarders that worked at Cann's and my father worked there. One Morning the RCMP showed up with a woman and two children a young boy about nine and his sister 5 or 6. Mother was told to call her Mr's Smith and she was not to tell anyone that she was there and to call if anybody came looking for her. Mother gleaned some of the story. The man was working in town as a dentist and he was foreign but well off and they dated and he proposed. She later found out he had married her in a rural Catholic Church when the real priest was off at a funeral. he had a friend pose as the priest. They then moved to Ontario. She then found he was German and a fan of hitler and raised the children to be little Nazis heiling and goose stepping and ignoring anything their mother said. she said he had a secret shortwave radio and sometimes disappeared for days. Finally she had had enough and went to the RCMP who brought her back to Cape Breton. The children continued their nazi ways to everyone's chagrin. And were cruel to their mother and did stuff like putting the cat in a box and kicking it down stairs. One of the boarder's Doug Hannon gave him a licking. So one day the local policeman showed up at the door with a stranger. He said that the man was looking for his wife and two children When they looked to the man he was gone. Mother screamed and the men who were having lunch came running and started looking for the man. Mother ran up stairs and cut the man off as he was coming up the back stairs. he tried to push her out of the way so she punched him in the mouth knocking out 3 teeth. This gave time for the police and the men to catch up and take him away. the RCMP were called and took them all away and mother never heard anything until about it 10 years later she got an anonymous letter thanking her and saying the children were now well behaved. it should be mentioned at the same time there was a saboteur scare on that somebody was putting bomb in the coal that the ships bunkered. My Mother was a strong determined Cape Breton women packed into 118 pounds.
