To address the elephant in the room, this full series is on YouTube, but blocked in the U.S. (I'm sure it's available elsewhere, but I'm poor). Switching my VPN to Switzerland did the trick, though I realize that's not an option for everyone.
I ran into a suggestion to watch this in a comment on a Reddit thread about Star Trek-adjacent series, given that Gene Roddenberry gave both William Shatner and Patrick Stewart the full set of 10 books (the TV series only covers the first three) and told them to use Hornblower as a template for how they'd play captains.
This was one of those rare series where the writing is sharp, the mysteries compelling, the production values outstanding and the acting superb.
Each "episode" is two-hours long (sounds like movie-length to me), so it's not just something to throw on in the background, because everything ties together both within each story and as a whole, and there are a couple of cliffhangers in the back half that kept me up way too late because I couldn't go to bed without seeing how things got resolved.
Anyway, strongly recommended.
