„“A lot of things seem to be happening, all at once,” I told Chester.
“Enemy action,” he replied.
“That’s what you told me once. An old Army motto you found when you were doing those war books. Once is happenstance, twice is coincidence, three times is enemy action. This is the third time.”“
— Michael Kurland American writer 1938
Chapter 2 (p. 22) Kurland is actually quoting here from Ian Fleming’s novel Goldfinger
