Trout has a personality as bland as his namesake, so he is a perfect fit for the Angels. Ohtani, on the other hand, I'm guessing he is gone as soon as his contract is up.
I’ve read a few in that series as well.
If you like Name of the Rose, Hild by Nicola Griffith is a book I’d recommend. It’s not a mystery, nor medieval, but the way it really creates a vivid setting is reminiscent of Rose.
