Von Fincke's expression changed. "Not so well as I hoped. The Secret Service are active in investigating all that are issued. It is difficult to circulate them under such espionage."

"It is risky," agreed Hartzmann. "Our agents have opened headquarters in New York. We hope to destroy by means of fire bombs British ships clearing from American ports."

"If that is accomplished, it will lend material aid to our war zone policy," exulted von Fincke.

"And later on we hope to establish the American seaports as bases for a fleet of naval auxiliaries, loaded with supplies for our swift submarines and cruisers. I am making arrangements for taking care of the necessary clearance papers."

"Excellent!" ejaculated von Fincke for the second time, and opened a notebook which he took from his dispatch-box. "Our reservists in this country report regularly. Under the guise of rifle clubs they keep themselves in excellent practice. Bodies of them are unobtrusively seeking employment along the Canadian border."

"Well done; it is a wise move." Hartzmann helped himself to a cigar. "What about this Spencer mystery, Baron? As our agent in Mexican affairs he received a small fortune. Does not his death come at a most unfortunate moment?"

Von Fincke pursed up his lips. "No. Spencer was a good tool, but sometimes too inquisitive; however, I shall not be sorry if Miss Whitney receives the full penalty for her crime." The two men regarded each other in silence for a brief second, then von Fincke added: "From reports which have reached me, I judge the mine is well laid, and Mexico will yet prove troublesome to her northern neighbor."

"And useful to us," mused Hartzmann. "The United States when angry with
Germany will make war—on Mexico."

"Perhaps," skeptically, "but to me it appears intervention in Mexico will hang fire until …"

"Engineered," Hartzmann smiled meaningly. "Huerta will leave shortly for the Panama-Pacific Exposition, and then …" Not completing his sentence, he pointed to a paragraph near the bottom of the first page of the Times which lay spread on the table by him. "The Sisters in Unity, I see, is a strictly neutral organization for peace at any price."
