“What river?”

“The Moselle. Heinie is camped on the other side of it, so be careful that you don’t get too near the bridge or you are liable to be picked up again. Come along, I’ll show you the way. It’s on my beat.”

Grace thanked him gratefully.

“You do not happen to know whether or not Captain Boucher is there, do you?”

The M. P. said he did not, but presumed so, for there was some sort of a council of war being held at the headquarters.

The M. P. left them at the door and Grace entered, halting when she found herself facing a sentry. She said she wished to see Captain Boucher on a matter of importance and asked the sentry to send her name in to the officer. The sentry told her he did not believe Captain Boucher wished to be disturbed, but she insisted that she must see him, so her name was sent in and Grace and Elfreda were seated in the hall.

The Intelligence officer came out immediately and greeted them with great cordiality.

“What can I do for you?” he questioned, smiling down into the flushed face of Grace Harlowe. “Is it something connected with the affair we were speaking of?”

“Not directly. The person that I said knew something about it is, I believe, working for us. I am quite certain that he will have something to report. Have you discovered anything?”

“I have verified your statement.” He smiled grimly. “Beyond that we have not gone. But you have something else to say to me?”
