“You will have time to make your arrangements.”

“I shall prepare, Excellenz.”

Captain Wentz rose, but the General halted him.

“One thing more. Herr Hammersley is returning tonight from England with dispatches. He is to be carefully watched tonight and tomorrow, though I shall let him believe that he moves in perfect freedom. You will give the necessary orders. Also I would like you to keep watch outside the door when he is brought to this room, which may be at any moment.”

Zu befehl, Excellenz.

“That is all. You may go.”

Left alone, General von Stromberg took a chair facing the fire, and lighted another cigar. For many years he had been engaged in deciphering interesting problems and in preparing problems for other persons to decipher. Therefore it may be truly said that his was the analytical mind, the mind of the chemist, of the mathematician, and the philosopher, with so complete a schooling in the trade of deception that all things and all persons in the cosmic scheme except himself were objects of suspicion. For him the obvious was the negligible and by converse the negligible of prime importance. As he had said to von Winden, every man was guilty until he was proven innocent. He had a rare nose for scenting unsuspected odors, and a fine hand for finding the weak links in the armor of those he used as well as of those who sought to use him. He had a faculty for appearing at places where he was least expected and a prescience almost miraculous in forestalling the moves of his adversaries. He ruled by fear and by admiration and there was not a man in the Empire with a skeleton in his closet, no matter how high his station, who did not live without a terror of von Stromberg in his heart.

But the habit of mind of suspecting everybody, while it had placed him upon the safe side of every equation, had also resulted, through the elimination of the sentimental, in eliminating the more direct contacts with human nature. To judge a man by his possibilities for venality is like judging a rose by the sharpness of its thorn. Something of the weakness of this cynicism had been apparent to the keen intellect of von Stromberg and he had been finding of late a rare pleasure in trifling with his convictions, admitting into the stored cavern of his mind for experimental purposes, an occasional ray of optimism. At the present moment he was analyzing the result of his summons to Herr Hammersley to come to Germany at once and the communication from Herr Rizzio which impugned Herr Hammersley’s loyalty to Germany. Von Stromberg had known Herr Rizzio for years and had done him more than one service in finding ways to cater to his passion for collecting objects of art. It was German social influence secretly exerted that had helped to make easy Rizzio’s rise in favor at the court of St. James. There had been a possibility that some day John Rizzio might be of service to von Stromberg and to Germany. And von Stromberg had long been laying the plans which had made his system of espionage the most perfect in Europe. Von Stromberg had found Rizzio’s weakness and had traded on it, saving his most tempting bait for his greatest service, the betrayal of the home of his adoption. He weighed Rizzio contentedly sure of his own power over him and despising him for having been so easily bought. Rubens’s “Descent from the Cross”! There were fortunately other Rubenses in conquered territory—some very good ones that John Rizzio might like. Von Stromberg had made a list of them. He had learned that it was as necessary to be provided with bribes as with threats. Fortunately Rizzio himself had given him material for the latter. Racially, the great Councilor did not like Latins, and he was quite sure he cared less for Italians now than he did before the proclamation of neutrality. They were not to be trusted by good Germans. If Rizzio had played false to the country of his adoption for the sake of a paltry picture, it was within the bounds of possibility that he could be false to Germany if the necessity arose for an even smaller consideration. Yesterday morning before leaving Berlin for Windenberg, von Stromberg had received a dispatch from Rizzio which told of his departure on his yacht from Scotland for Bremen. This was curious—also interesting. Rizzio was needed in England and was useless in Germany. Why was he coming? Had something been learned of him at Scotland Yard? Or had his departure to do with the case of Herr Hammersley? Whatever the visit meant, it was necessary, very necessary, to have Rizzio and Hammersley together at once, so he had deemed it wise to send orders to Bremen to have Rizzio caught on the wireless and when he reached port sent through at once to Windenberg.

Von Stromberg smiled in self-gratulation. There would be no loose ends about this affair. Merely as a precaution in so important a matter he had set one agent to watch another. Byfield had been watched by Hammersley, who in turn had been watched by Rizzio, who had been watched by Herr Maxwell, an agent long in von Stromberg’s service. Rizzio had been given the power and credentials to use his discretion with Hammersley. Why had not Hammersley relinquished the cigarette papers to Rizzio? Hammersley should have good reasons for his refusal. Was there reason for Hammersley to suspect Rizzio? Herr Maxwell, who had been set to watch Rizzio, was silent. This was puzzling. What had happened to Herr Maxwell?
