"What on earth do you mean?" said the Duke.

"I'm not joking," said Germaine. "Odd things are happening. Some one
has been changing the place of things. That silver statuette now--it
was on the cabinet, and we found it moved to the piano. Yet nobody
had touched it. And look at this window. Some one has broken a pane
in it just at the height of the fastening."

"The deuce they have!" said the Duke.




CHAPTER IV

THE DUKE INTERVENES


The Duke rose, came to the window, and looked at the broken pane. He
stepped out on to the terrace and looked at the turf; then he came
back into the room.

"This looks serious," he said. "That pane has not been broken at
all. If it had been broken, the pieces of glass would be lying on
the turf. It has been cut out. We must warn your father to look to
his treasures."

"I told you so," said Germaine. "I said that Arsene Lupin was in the
neighbourhood."
