The next morning, an officer led him, through a courtyard filled with soldiers, to the centre of a long row of buildings that ran round the foot of a mound covered with monumental ruins.

He was shown into a large, hastily-furnished room. His visitor of two days back was sitting at a writing-table, reading newspapers and reports, which he marked with great strokes of red pencil:

"Leave us," he said to the officer.

And, going up to Lupin:

"The papers."

The tone was no longer the same. It was now the harsh and imperious tone of the master who is at home and addressing an inferior . . . and such an inferior! A rogue, an adventurer of the worst type, before whom he had been obliged to humiliate himself!

"The papers," he repeated.

Lupin was not put out of countenance. He said, quite calmly:

"They are in Veldenz Castle."

"We are in the out-buildings of the castle. Those are the ruins of Veldenz, over there."
