Description: From Goodreads:

The Nazi past becomes ominously present as a man sets out to find a gay man swept away decades earlier in Germany's lethal purges. The story ranges from the vivid Berlin of 1935 to a postwar Germany where past evils retain a powerful hold on the present. The story is driven by secrets that, once discovered, reveal the story of gay men in Nazi history.
