I learned he was doing this when I saw Black Chamber and Theater of Spies on our library's new fiction shelf. Apparently it's quite new. "Jun 2019" stamped inside the cover. Some claptrap comparing it to James Bond in a couple blurbs. Stirling did a shout-out to Ian Fleming in Marching Through Georgia. Anyone besides me know of it? Anyhow. I am reading it. So far... Spoiler: It's a total Teddy-wank.
