At what level is the book pitched? Detailed technical tome or pop-sci?

I was hugely disappointed by Blind Man's Bluff despite all the praise for it as it was written for a lay-audience.

Blind Man's Bluff is a history of submarine espionage for a mainstream audience. I'm not sure what else one would reasonably expect of it.

Hot Spot of Innovation about Doc Draper and inertial guidance isn't academic but it does go into quite a bit of technical detail.

Some details - it’s an academic study, definitely not pop-sci.
