"Somebody telephoned Lena about meeting them there this evening."
"Yes, it was Mueller. He thought he had a recruit in me."
"Well, Heinrich," said Mr. Cook, "I guess that explains pretty nearly everything, and I'm sorry I ever suspected you." He shook hands warmly.
"Oh, that's all right," smiled Heinrich. "I had to get suspected with the job I had. That was part of the game."
At that moment the door bell rang and Dr. Clarke was ushered in. "I thought you might be interested in the hospital patients," he said. "Mr. Wernberg will recover all right, and Lena is not badly hurt. She keeps calling all the time for somebody named Heinrich. Do you know him?"
"Will you excuse me, Mr. Cook?" exclaimed Heinrich, and, without waiting for a reply, he dashed out of the room, nearly falling over two chairs in his haste to get away to the hospital.
"He seems to be in a hurry, doesn't he?" laughed the doctor.
"I must be going, too," said Sergeant Riley. "I have some boarders down at my hotel who may need attention."
"Well, good-night, Sergeant," exclaimed Mr. Cook, shaking hands with the doughty officer. "I'm sorry Hoffmann was mixed up in this business, but I'm glad it's all cleared up. I hope we'll have no more trouble."
"Ye won't, as long as yez have two young fellers like Bob and Hugh working for yez," exclaimed Riley. "The United States needs boys like that; this war is going to be a long and hard one in my opinion."
