“I should like to meet that clerk face to face,” I burst forth. “He tells a distinct falsehood when he says he recognises me. I did not go into the Strand at all on that day.” Then a thought suddenly occurred to me when I reflected upon the shape of my hat, and I added, “I admit that my hat is of a rather unusual shape,” taking it up and exhibiting it to them. “But when I bought this in Piccadilly two months ago Ogle was with me, and he purchased one exactly similar.”

“Again the evidence is against the dead man,” the Premier said, turning to Lord Warnham. “Where is his hat?” he inquired of me sharply.

“At Shepperton. I can produce it if required. Its shape is exactly like mine.”

“You had better speak to Frayling upon that point,” observed Lord Warnham. “It may prove important. At any rate, Deedes, perhaps, after all, I have been just a trifle unjust in condemning you, therefore consider yourself reinstated in the same position as before, although I must admit that my previous confidence in your integrity is, to say the least, seriously—very seriously—impaired.”

“I hope it will not remain so long,” I said. “If there is anything I can do to restore your belief in my honesty, I will do it at whatever cost.”

“There is but one thing,” he exclaimed. “Discover the identity of the spy.”

“I will regard that the one endeavour of my life,” I declared earnestly. “If the mystery is to be fathomed I will accomplish it.”

“While we’ve been talking,” the Premier interposed, “a thought has occurred to me, and for mentioning it I hope you, Deedes, will pardon me. It has struck me that if, as seems even more than likely, this man Ogle was actually a spy who had carefully cultivated your acquaintance with an ulterior motive, is it not within the range of possibility that the lady, who was also your most intimate friend, as well as his, either knew the true facts, or had a hand in the affair?”

“I can trust Ella,” I said, glancing at him resentfully. “She is no spy.”

The elderly statesman stroked his beard thoughtfully and smiled, saying, “Ah, I expected as much. I myself was young once. When a man loves a woman he is very loth to think her capable of deceit. Yet in this instance we must not overlook the fact that more than one female spy has been brought under our notice.”
