"I fear not. He was standing in the shadow, and I was preoccupied and barely glanced at him. I cannot even say that it was not Schroeder."

"I do not believe it was any member of my crew," said the Captain.

"Then who was it?"

"That, of course, I cannot say. But why should one of my crew do such a thing?"

"There may be a traitor among them."

"We know the history of every man. They are all good Germans. We are very careful. But even if there was a traitor, how would he know of this conference?"

Pachmann threw up his hands with a gesture of despair, and dropped into a chair.

"How would any one know?" he demanded. "I mentioned it to no one but the Prince and yourself. Vard himself did not know of it till I summoned him."

Hausmann looked at the speaker steadily.

"I trust that you are not insinuating that it is I who am the traitor?" he asked.
