Kaleb Lyonnais has provided more information on the meaning of the French quote at the bottom of this mystery message. He writes:
“I have a translation for the French quote in the mystery message.
It says: “Speak my girlfriend in Lyon I have would love she often.”
The apparent grammar errors in my translation reflect some of the grammar errors in the quote, but the quote also had spelling errors.”
Perhaps Agent Canton was in a rush to finish his message. In any case, thanks to Kaleb for a translation!
