Kate Atkinson's One Good Turn
This is a sequel to Case Histories, which I read a couple years ago and vaguely recall being a literary-fiction-meets-mystery sort of affair, with lots of likable characters and different storylines that gradually interwove. This is more of the same, as retired cop/private eye Jackson Brodie travels to Edinburgh (along with thousands of other people) for some sort of theatre festival. Murder and mayhem ensue along the way, as Brodie and the reader try and fit everything together (it's clear to the reader pretty quickly that these things are laced together). Still, it resolves nicely, and again Atkinson's characters are likeable and interesting. A pretty entertaining read, for sure.
