'This is a very fine spy story. A lieutenant-commander invents a gun-control mechanism which would enable the British Fleet to beat all-comers. The Germans hear of this, and engage a dissatisfied and beautiful young Englishwoman to extract from him the secret. She worms her way into his confidence, gets hold of his plans, and takes them to the German Embassy. There she finds she loves the lieutenant, and then begins a battle of wits between the woman and the astute Germans. Complication follows complication, and some vary dramatic situations crop up. In the long run—but why spoil the reader's zest for a story which he or she is bound to go right on with at one sitting.'
