“Now, Captain Griffiths,” she began, “do listen to me. Just one moment of common sense, if you please. What do you suppose there could possibly be in our harmless seaside village to induce any one to risk his life by coming here on behalf of the Secret Service of Germany?” “Dreymarsh,” Captain Griffiths replied, “was not made a prohibited area for nothing.” “But, my dear man, be reasonable,” Philippa persisted. “There are perhaps a thousand soldiers in the place, the usual preparations along the cliff for coast defence, a small battery of anti-aircraft guns, and a couple of searchlights. There isn't a grocer's boy in the place who doesn't know all this. There's no concealment about it. You must admit that Germany doesn't need to send over a Secret Service agent to acquaint herself with these insignificant facts.” Her visitor smiled very faintly. It was the first time he had relaxed even so far as this. “I am not in possession of any information which I can impart to you, Lady Cranston,” he said, “but I am not prepared to accept your statement that Dreymarsh contains nothing of greater interest than the things which you have mentioned.” There was no necessity for Philippa to play a part now. The suggestion contained in her visitor's words had really left her in a state of wonder. “You are making my flesh creep!” she exclaimed. “You don't mean to say that we have secrets here?” “I have said the last word which it is possible for me to say upon the subject,” he declared. “You will understand, I am sure, that I am not here in the character of an inquisitor. I simply thought it my duty, in view of the fact that you had made yourself the social sponsor for Mr. Lessingham, to place certain information before you, and to ask, unofficially, of course, if you have any explanation to give? You may even,” he went on, hesitatingly, “appreciate the motives which led me to do so.” “My dear man, what explanation could I have?” Philippa protested, “it is an absolute and undeniable fact that Mr. Lessingham was at Magdalen with my brother, and also that he visited us at Wood Norton. I know both these things of my own knowledge. The only possible explanation, therefore, is that you have been misinformed.” “Or,” Captain Griffiths ventured, “that Mr. Hamar Lessingham in those days passed under another name.” “Another name?” Philippa faltered. “Some such name, perhaps,” he continued, “as Bertram Maderstrom.” There was a short silence. Captain Griffiths had leaned back in his chair and was caressing his upper lip. His eyes were fixed upon Philippa and Philippa saw nothing. Her little heel dug hard into the carpet. In a few seconds the room ceased to spin. Nevertheless, her voice sounded to her pitifully inadequate. “What an absurdity all this is!” she exclaimed.
