The Cairo Affair: Library Edition

I love how the author has each section being told from the perspective of one of the main characters, with each filling in gaps in the understanding. Thankfully when the author has the proverbial lightbulb go off over someone's head about who did what when, some of the information is made clear in the next section.

A good who-dun-it, with good character building, and the mystery not solvable too soon.
