Edgar Wallace,
The Superspy
(1918)
“ For example, we had foreseen the necessity in organizing our intelligence department, to employ not Germans, but subjects of neutral states wherever possible. People who talk of “German spies” or “the uninterned German peril” cannot realize that from the moment war broke out, all Germans known as-such, were under the observation of the police and not only the police but their own neighbors. It would be impossible, as I had foreseen, for such men to offer assistance to our great and splendid cause, because the least suspicious movement on their parts would result in their arrest. ”
