Of course, had she tried to enter the major's offices, the sentinel would have stopped her. But that was not her object.
If Frank Sanderson was still here he must be somewhere in the wing of the building in which poor Erard had spent a few brief hours in a cell.
The prisoners were down there. On the upper floors were offices and the quarters of some of the baron's staff. One of these rooms was that, it might be, in which Sanderson was detained until Doctor Herschall had decided upon his case.
Necessity made Belinda bold. She selected a side entrance of this wing well away from the main door of the château and approached quickly. Soldiers and servants were hurrying about. Two great motor-trucks were backed up here and into them the personal belongings of the staff were being loaded.
Retreat was expected, if it had not already been ordered.
In the doorway stood a soldier, his back to the nurse as she drew near.
"Will you please tell me," she began softly, when he wheeled and she beheld Paul Genau.
"Belinda!" he exclaimed.
"Oh, Paul! I am so glad to see you are safe. And Carl?"
"Ach! You can't kill that thickhead," declared the sergeant-major. "He and I were in a raid last night; just back from the front now. He's gone to have his head sewed up. He led his squad in a charge and tried to kill a Frenchman by butting him to death like a goat. And, mein Gott! I believe Baum succeeded. He'll get the Iron Cross for it, I have no doubt, der Glückshund!
