IF ENGLAND KNEW


No sane person can deny that England is in grave danger of invasion by
Germany at a date not far distant.

This very serious fact I endeavoured to place vividly before the public
in my recent forecast, _The Invasion of 1910_, the publication of which,
in Germany and in England, aroused a storm of indignation against me.

The Government, it will be remembered, endeavoured to suppress its
publication, because it contained many serious truths, which it was
deemed best should be withheld from the public, and on its
publication--in defiance of the statements in the House of Commons, and
the pressure brought upon me by the Prime Minister--I was denounced as a
panicmonger.

But have not certain of my warnings already been fulfilled?

I have no desire to create undue alarm. I am an Englishman, and, I hope,
a patriot. What I have written in this present volume in the form of
fiction is based upon serious facts within my own personal knowledge.

That German spies are actively at work in Great Britain is well known to
the authorities. The number of agents of the German Secret Police at
this moment working in our midst on behalf of the Intelligence
Department in Berlin are believed to be over five thousand. To each
agent--known as a "fixed-post"--is allotted the task of discovering some
secret, or of noting in a certain district every detail which may be of
advantage to the invader when he lands. This "fixed-agent" is, in turn,
controlled by a travelling agent, who visits him regularly, allots the
work, collects his reports, and makes monthly payments, the usual
stipend varying from L10 to L
