Charlie in Mademoiselle Holmes is portrayed as having autistic traits, and some viewers and write-ups describe her as representing autism spectrum disorder rather than giving her a formal diagnosis in the show. The series synopsis focuses on an accident that awakens her detective abilities, not a stated medical label.

What the show implies

  • PBS describes Charlie as a timid police officer whose deductive brilliance is awakened after an accident.
  • A discussion of the character on Reddit explicitly calls her a representative of autism spectrum disorder.
  • In the episode summaries I found, there is no official in-show diagnosis attached to Charlie.

Practical read

So the safest answer is: there is no confirmed diagnosis stated in the series itself ; the character is generally interpreted by viewers as being written with autistic characteristics.

Note

If you meant a different “Charlie” from another PBS title or a different series, tell me the exact show name and I’ll pin it down more precisely.
