Unfortunately starting in the late 30s and 40s Celine became a virulent anti-semite and was a nazi sympathizer during the occupation. After the war he went into exile in Denmark and was tried in absentia in France and was convicted of collaboration and sentenced to one year in prison and a fine of 50,000 Francs and the confiscation of half his property. His sentence was commured and he returned to Framce where he re-registered as a doctor, opened a clinic, and continued writing.
