Opinions of the London Press.
The Times says: "Everything that can spice a sensational volume."
The Morning Post says: "Few works can compare in stirring incidents or careful elaboration of detail.... A great deal of what he forecasts would be very likely to occur if once England were in the clutches of a strong enemy, and in the matter of description wherein the tumult and carnage is brought vividly before the reader.... A clever and exciting book."
The Standard says: "Full of excitement and realism."
The Globe says: "It is vigorous and rousing.... Will do a public service."
The Sun says: "Mr. Le Queux' narrative is well and spiritedly written."
The Evening News says: "Mr. Le Queux has succeeded in a very difficult task. He has brought home to us the dangers we expose ourselves if we neglect to maintain our Army and Navy in an adequate state of efficiency."
The Daily Graphic says: "Various essays have been made to forecast the next great European war, but Mr. William Le Queux' volume is certainly the most comprehensive and thrilling of anything yet attempted. Regarded simply as a work of fiction, it is exciting enough to satisfy the most enthusiastic lover of 'blood and thunder' literature. In its more serious aspect—and it is this aspect, of course, which the author desires for it—this book certainly evidences serious thought.... It is all very graphic and very thrilling, especially the bombardment of London by the Russians, and the author has not scrupled to avail himself of the latest, even of the future, resources of science."
Naval and Military Record says: "Mr. Le Queux has special qualifications for the task. He knows a great deal of our Army and Navy, and he is familiar with continental systems and sentiment. The narrative is lively and spirited, and the author writes with an air of conviction which is calculated to carry the reader on from beginning to end."
Admiralty and Horse Guards Gazette says: "Mr. Le Queux is a vivid writer, and his work gives evidence of care and thoroughness. The chapter dealing with the march of the French on London is particularly fine. The author's production is the best of the kind we have come across for some time. It should emphasise our old contention as to the unreadiness for active service on a prolonged campaign of the sea and land forces of the Empire."
