Hercule Poirot/WMG

Hercule Poirot is the ancestor of Adrian Monk
Two Words: Super OCD. Perhaps Poirot and Countess Vera Rossakoff had more than a little admiration for each other...

The detective we see on screen is not Poirot
Whoever he is, he refers to Poirot in the third person. Is it possible that Poirot is really like Mycroft Holmes, a figure hidden from the world and only in contact via an accomplice?
