I enjoyed Delete All Suspects and its (first?) sequel, although not as much as Andrews' other series. (In that one, the detective is a blacksmith! There's not enough blacksmithing in it—I'm not sure the protagonist ever smiths on page, although she does talk about her work and sell her pieces—but I like the main character and the weirdness of the rest of the cast. (IIRC I liked Turing herself, and the other prominent AI character, but the human characters made precisely no impression on me.)

The rest of the titles aren't familiar to me, so I voted based on how entertaining the protagonists' day jobs sounded.

I have not read Alph, but I approve of killing it; I can't remember any other book getting no Fs.
