The Way to Win by William Le Queux

I may fairly claim to have taken perhaps a leading part in bringing home to the people of this country a realisation of the perils to which our foolish good nature has exposed us in the matter of the spy danger.

Though I am quite willing to admit that much has been done by our excelled Intelligence Department in putting a check upon the activities of the German spies since the War began, I cannot but confess that I look upon the continued presence in this country of some 22,000 German and Austrian enemies, allowed for the most part to go freely about their business, whatever it may be, with unmixed alarm.
