I've been meaning to pick this up for ages, ever since I read Walton's reviews of the Vorkosigan Saga and thought "Yay, kindred spirit, I bet her writing is wonderful!"

I love being right. Though this is decidedly not scifi, it draws on similar skills in its ability to evoke a world that never was, but could have been. Her alternate England, in which peace is brokered between Britain and Hitler, is chillingly rendered and wonderfully, terrifyingly real. She's an incredible investigator of how and why good people come to do bad things.

Farthing uses the frame of the English mystery novel to tell a chilling story about people and humanity and what might have been. The combination of alternate universe with Sayers-esque whodunnit makes for a great story and I cannot wait to pick up Ha'penny, the next book in the series.
