My Adventures as a Spy, by Lieut.-Gen. Sir Robert Baden-Powell, K.C.B. All about the author's experiences in espionage. There are narrow escapes through the climbing of scaffolding, mountaineering, experiences in South Africa, and counter-espionage.
The scout is looked up to as a brave man, and his expedients for gaining information are thought wonderfully clever, so long as he remains in uniform. If he goes a bit further, and finds that he can get his information better by adopting a disguise—even at the greater risk to himself through the certainty of being shot if he is found out—then he is looked down upon as a "despicable spy." I don't see the justice of it myself.
A good spy—no matter which country he serves—is of necessity a brave and valuable fellow.
And illustrations of how to conceal a sketch of a fortress in a butterfly's wings:

(Splotches on the lines are the fortress' guns, and positioned where the line extends inside the outline of the fortress.)
Fascinating, informative, and biographical.
