Professor T was an English version of the Belgian Professor T. The Belgian one was better. But, know beats Frances de la Tour.
Of course, the same with Patience and Astrid. Astrid is more 'autistic than Patience in her mannerisms. There is better a better back story, how Astrid learnt from her father how to assess cases.
I love Astrid's support group, it's really informative and revealing. I have a non-verbal autistic young man, and any insights and different ways of understanding him are welcome.
But, with support was able to pass her police exams which were requested by the Police Commissioner after a gruesome case. Doing that, improved her self confidence, knowledge and skills.
However, I am glad there is some deviation from the plot lines to the Astrid drama.
