The Suspicions of Mr Whicher

The Suspicions of Mr Whicher - Trailer
The Blazers got blown out of the NBA playoffs by the New Orleans Pelicans, so that's it for basketball for us for the season, so now we can devout ourselves full-time to watching murder mysteries.

Looks like there are four movie-length episodes in this series. The Murder at Road Hill House was the first one. It is set in England in the 1860 and is based on a true story. Everything is very similar to modern day police investigations, but everything is different. In particular, perceptive intelligence and rudimentary psychology are Mr. Wicher's primary tools. He figures out what happened, but it isn't until years later that he is vindicated. Is that a spoiler?

On Amazon Prime. There are also a bunch of videos on YouTube that claim to be the full movie, and with running times of an hour and a half, they might lure you into thinking that, hey, free movie! But the few I looked at turned out to be bullshit, ads for a streaming service of some kind.
