This was my 2nd of three CYOA books I wrote as a kid. The first - 'The Mystery of the Mysterious Time Machine' is on this site already. When I recently found this old book it had the title page 'A Dangerous Mission'. But I for sure remember that wasn't the original title. It was something like 'The Mystery of the Missing Microdot' or maybe 'Find the Missing Microdot'. The idea of the microdot itself I totally remember where it came from. Along with being a big Dungeons & Dragons fan I also played many of TSRs other games. 'Top Secret' being a fave (and let's not forget 'Boot Hill' and 'Gamma World'!). Anyway, 'the microdot as I way for spies to transport information must have popped up in the 'Top Secret' game and I ran with it. This was probably written around 1982 I'm guessing. Whereas I kept my first book exactly as I wrote it thought I might update this one a little as i go. But all of the choices will be the same.
