Just finished up Prague Fatale and it is a great return to form for the Gunther novels. To be honest, I wasn't crazy about the last few, feeling they meandered too much. But returning to 1941 also means a return to a tighter novel with a pretty good mystery. I gave it ★★★★✩ in my Goodreads review: http://www.goodreads.com/review/show/241270663
have you had a chance to read it yet?
