Mouse P.I. For Hire review: a monochrome tale with a ton of personality

Noir fiction works best for me when it's played straight: hardboiled, down-on-their-luck detective, trying earnestly to carve out a corner of the world where they can drink themselves into oblivion. I'm a simple man with simple tastes. A noir detective story where the protagonist (and the majority of the world, for that matter) are mice? I don't know about that.
