“Describe its manner of flight, if you can, please, and the point where you saw it.”

“The bird spiralled up after a little apparent uncertainty, then taking a direct line, streaked it to the eastward. Two others followed it at regular intervals. That was at Etain, and the birds were flown from a little patch of woods to the south of the ruined village. I have seen many pigeons flown in this war, Captain Boucher, and I am familiar, in a way, with their methods of operating.”

“You surely have described it properly. You only saw three birds go up?”

“That was all I saw at Etain.”

“You have seen some since?” asked the general quickly.

“Yes, sir. Three more were liberated from a field just at break of day this morning. They too went east.”

“Most remarkable,” declared the major gazing at her admiringly. “Our Intelligence Department is obtaining some real intelligence.”

“Yes, here’s a job for you, Captain. I’ll warrant you are up at break of day to-morrow morning,” chuckled the general.

“This is a serious matter, General,” reminded the captain. “It doesn’t seem possible that a thing like that could be pulled off under the very eyes of the army. However, if your information is correct, we shall catch the culprit. May I ask you to take an early observation again in the morning, Mrs. Gray?”

“I shall be pleased to do so. If I may make a suggestion, I would urge you to discuss nothing of this before the Chinaman. I observed that the general sent him away before we began speaking; else I should not have told you what I have,” said Grace.
