“We could not, and we will not,” Hayter interrupted fiercely. “Unless you wish me to denounce you at home as a renegade and a coward, you will go through with the work which has been allotted to you. Your earlier mistakes will be forgiven if that chart is in my hands by Friday.”

“But how do you know that he will have it?” Lessingham protested. “Supposing you are right and he is really responsible for the minefields you speak of, I should think the last thing he would do would be to bring the chart back to Dreymarsh.”

“As a matter of fact, that is precisely what he will do,” Hayter assured his listener. “He is bringing it back for the inspection of one of the commissioners for the east coast defense, who is to meet him at his house. And I wish to warn you, too, Maderstrom, that you will have very little time. For some reason or other, Cranston is dissatisfied with the secrecy under which he has been compelled to work, and has applied to the Admiralty for recognition of his position. Immediately this is given, I gather that his house will be inaccessible to you.”

Lessingham sat, his arms folded, his eyes fixed upon the fire. His thoughts were in a turmoil, yet one thing was hatefully clear. Cranston was not the unworthy slacker he had believed him to be. Philippa's whole point of view might well be changed by this discovery—especially now that Cranston had made up his mind to assert himself for his wife's sake. There was an icy fear in his heart.

“You understand,” Hayter persisted coldly, “what it is you have to do?”

“Perfectly. I shall return by the afternoon train,” was the despairing reply.

“If you succeed,” Hayter continued, “I shall see that you get the usual acknowledgment, but I will, if you wish it, ask for your transfer to another branch of the service. I am not questioning your patriotism or your honour, Maderstrom, but you are not the man for this work.”

“You are right,” Lessingham said. “I am not.”

“It is not my affair,” Hayter proceeded, “to enquire too closely into the means used by our agents in carrying out our designs. That I find you in London in company with the wife of the man whom you are appointed to watch, may be a fact capable of the most complete and satisfactory explanation. I ask no questions. I only remind you that your country, even though it be only your adopted country, demands from you, as from all others in her service, unswerving loyalty, a loyalty uninfluenced by the claims of personal sentiment, duty, or honour. Have I said enough?”

“You have said as much as it is wise for you to say,” Lessingham replied, his voice trembling with suppressed passion.
