#33 Lehrter Station, by David Downing

I like the John Russell series a lot; in this book WWII is now over and John and his sweetie Effi return to the runs of Berlin to begin to tie up some loose ends and continue trying to wriggle free from his Soviet entanglements. Like the earlier books, it presents a grim picture of life in a time of war, with a dose of cynicism but not without a sense of honor and even hope.
