Pretty good Italian who-dunnit series, with a grumpy, woman chasing detective. 2 seasons so far, 3 is coming soon.

I just finished watching the first season since it's only on until Jan 31 and thoroughly enjoyed it. I hope they put the second season on Prime after the 31st because now they want you to sign up for some premium PBS plan to see it.

Thanks for the recommendation.
