I am watching on Tubi
The aristocratic Detective Chief Inspector Alleyn and his Scotland Yard assistants investigate a series of crimes with the detective moving casually through the world of high society. Each episode is a complete murder case that is solved so you can watch and not have to keep up with the previous episode. DCI Alleyn wears the most beautiful double-breasted suits and he is never disheveled. He's very well educated with impeccable manners and a keen eye for detail. His love interest, an artist named Troy, is in every episode.
Please note that the lead actor that plays Alleyn in episode one is replaced by another actor in all the subsequent episodes. When BBC picked up the pilot the actor from Season 1, Episode 1 was not available. This confused me no end so I will spare you from wondering what happened.
Brenda recommended this series in the comments below my post about MONARCH OF THE GLEN. I finished that series and LOVED it and now I am loving Inspector Alleyn Mysteries. It is free on Tubi. I think it's on Amazon Prime too and maybe YouTube. I promise you will like it.
