Помогите перевести (без переводчика).

Stephane Breitweiser, 33, from Alsace, in France, is the greatest art
thief in Europe. For over six years, while he was working as a lorry
driver, he stole 239 paintings from museums in France, Austria, and
Denmark. He went into the museums just as they were closing and
hid the paintings under his coat. Nobody looked at him because he
was wearing a security guard’s uniform. Back in his apartment,
where he was living with his mother, he filled his bedroom with
priceless works of art. His mother, Mireille, 53, thought all the
paintings were copies. One day while they were having supper, the
police arrived, and they took Stephane to the police station. Mireille
was so angry with her son that she went to his room, took some
paintings from the walls, and cut them into small pieces. Others she
took and threw into the canal. Altogether she destroyed art worth two
billion dollars! Both mother and son spent many years in prison
