Again she crossed to that huge green-painted safe let into the wall, which contained her father’s secrets—and many of the military secrets of the kingdom of Italy—and taking a hairpin from her tightly bound tresses—always the most handy feminine object—she broke off a piece of the wire about an inch long, which she carefully inserted in the keyhole, poking it well in by means of the other portion of the pin until she heard it fall with a click into the delicate mechanism of the lock.
Then, smiling to herself, she withdrew, knowing that whatever attempt Dubard now made to reopen that door would be without avail. There was nothing to show that anyone had interfered with the mechanism, therefore he would be entirely unsuspecting, and would attribute the non-working to some defect in the lock itself, or in the key.
That night she sat next him at dinner, bearing herself as bravely bright and vivacious as ever, and determined that his suspicions should not be aroused; while he, on his part, thought her more charming than ever.
The evening passed as usual in the small drawing-room with music and gossip, and later, after all had retired and one o’clock had struck, Mary crept out in the darkness to the library, where, sure enough, she saw, on peering through the keyhole, the man who was so cleverly courting her actively trying to open the safe door.
The key would only half turn, and in French he muttered some low words of chagrin and despair. He tried and tried, and tried again, but all to no purpose. He withdrew the key, blew into the barrel, examined it in the light, and then tried once more.
But the lock had become jammed, and neither by force nor by light manoeuvring could he turn the key sufficiently to shoot back the huge shining bolts that held the door on every side.
Mary’s effort had been successful. By that tiny piece of wire her father’s secrets were held in safety.
