Astrid , murder in paris . A great actress plays an autistic woman who helps a police commander solve murders , each one is a stand alone but to understand her and how she evolves it is best to start from season one , season three is currently on C4 . I watched the first ep season one and was really annoyed with the character but walter presents has never let me down yet so i watched ep two and really got into it . The actress is not autistic and is a well known actress in france , she has done a brilliant job. Also nice that the two leads are women
