"The boy has not had time to confess the secret,"—the thought almost rose to the colonel's lips.—"If this unknown man returns to town, leaving Gulian here, all will yet be well."

The hall-door opened again, was locked, and the form of the unknown, in cloak and sombrero, once more appeared upon the garden walk.

"To town, Felix, as fast as you can drive. I must be back within two hours."

"Yes, my lord."

He entered the carriage,—it turned,—and the horses dashed up the narrow road at full speed.

"Two hours!" ejaculated Tarleton, as the sound of the wheels died away. "In two hours, 'my lord!' you will find the nest robbed of its bird."
