Another solid Cold War novel from Derek Lambert.
Originally written in 1985, it follows Robert Calder: a defector from the US to Russia, who bought his safety by providing explosive information, he now wants to return to the West. Now, he has two Russian operatives on his trail, and his life is on the line.
It's another good novel (albeit a bit dated in certain... conventions). Well-paced and enjoyable.

I discovered Derek Lambert through net galley and I am really glad that I did because it's right up my alley. I love the period his books are set in and the story lines, cold war society thrillers are great and his writing is fantastic, even if the story lines are sometimes reminiscent of other minor plots in his other books.
