“Ah! they are there!” he repeated, to himself; “they are there!”
A friendship formed under such circumstances soon led to closer relations. When discreetly questioned, Arsène Lupin confessed his poverty and distress. Immediately, the unfortunate young man was appointed private secretary to the Imberts, husband and wife, at a salary of one hundred francs a month. He was to come to the house every day and receive orders for his work, and a room on the second floor was set apart as his office. This room was directly over Mon. Imbert’s office.
Arsène soon realized that his position as secretary was essentially a sinecure. During the first two months, he had only four important letters to recopy, and was called only once to Mon. Imbert’s office; consequently, he had only one opportunity to contemplate, officially, the Imbert safe. Moreover, he noticed that the secretary was not invited to the social functions of the employer. But he did not complain, as he preferred to remain, modestly, in the shade and maintain his peace and freedom.
However, he was not wasting any time. From the beginning, he made clandestine visits to Mon. Imbert’s office, and paid his respects to the safe, which was hermetically closed. It was an immense block of iron and steel, cold and stern in appearance, which could not be forced open by the ordinary tools of the burglar’s trade. But Arsène Lupin was not discouraged.
“Where force fails, cunning prevails,” he said to himself. “The essential thing is to be on the spot when the opportunity occurs. In the meantime, I must watch and wait.”
He made immediately some preliminary preparations. After careful soundings made upon the floor of his room, he introduced a lead pipe which penetrated the ceiling of Mon. Imbert’s office at a point between the two screeds of the cornice. By means of this pipe, he hoped to see and hear what transpired in the room below.
Henceforth, he passed his days stretched at full length upon the floor. He frequently saw the Imberts holding a consultation in front of the safe, investigating books and papers. When they turned the combination lock, he tried to learn the figures and the number of turns they made to the right and left. He watched their movements; he sought to catch their words. There was also a key necessary to complete the opening of the safe. What did they do with it? Did they hide it?
One day, he saw them leave the room without locking the safe. He descended the stairs quickly, and boldly entered the room. But they had returned.
“Oh! excuse me,” he said, “I made a mistake in the door.”
“Come in, Monsieur Lupin, come in,” cried Madame Imbert, “are you not at home here? We want your advice. What bonds should we sell? The foreign securities or the government annuities?”
