\"The Title story of this volume was written about eighteen months before the outbreak of the war, and was intended to direct public attention to the great danger which threatened this country. It is a matter of history how fully this warning has been justified and how, even down to the smallest details, the prediction has been fulfilled.\" \"It is an amazing thing that the English, who have the reputation of being a practical nation, never saw the danger to which they were exposed. For many years they had been spending nearly a hundred millions a year upon their army and their fleet. Squadrons of Dreadnoughts costing two millions each had been launched. They had spent enormous sums upon cruisers, and both their torpedo and their submarine squadrons were exceptionally strong. They were also by no means weak in their aerial power, especially in the matter of seaplanes. Besides all this, their army was very efficient, in spite of its limited numbers, and it was the most expensive in Europe. Yet when the day of trial came, all this imposing force was of no use whatever, and might as well have not existed.\" [...] Collection of mysterious and thrilling short stories by the creator of famous Sherlock Holmes and Dr. Watson. Originally published in 1918.
