"Yes. The road to the west is shorter. It is not more than seven miles that way."

Halkett casually counted the sea gulls. Seven gulls were flying around one of the ships; thirteen around another.

"And the river road, Sister?" he inquired.

"By the quarry bridge? Oh, that is longer—perhaps twelve or thirteen kilometers."

"I see.... Rosières-sous-Bois is not a garrison town?"

"No. There are only a few gendarmes there."

Halkett examined the picture attentively. The sun appeared to be about three hours high above the horizon.

"The nearest military post must be about three hours' journey from here," he ventured.

Sister Eila thought a moment, then nodded:

"Yes, about three hours. You mean the fort above the Pass of the Falcons? That is the nearest."
