Transcription of the letter just in case: "To Monsieur, the Detective. In regard to the case of Jean’s purloined painting. Let this serve as fair warning, stay out of this matter that is not of your concern. I bear no ill will towards you, but should you choose to disregard this message, I will be forced to take action. Leave it be. Sincerely, A well-wisher" Have a great carnival!
