Two of the keys entered the lock, and one of them. turned round once, but not the second time.
There was therefore only a little to be done to this key.
Boxtel covered it with a slight coat of wax, and when he thus renewed the experiment, the obstacle which prevented the key from being turned a second time, left its impression on the wax.
It cost Boxtel two days more to bring his key to perfection, with the aid of a small file.
Rosa’s door thus opened without noise and without difficulty, and Boxtel found himself in her room alone with the tulip.
The first guilty act of Boxtel had been, to climb over a wall in order to dig up the tulip; the second, to introduce himself into the dry-room of Cornelius, through an open window; and the third, to enter Rosa’s room by means of a false key.
Thus envy urged Boxtel on with rapid steps in the career of crime.
Boxtel, as we have said, was alone with the tulip.
A common thief would have taken the pot under his arm, and carried it off.
But Boxtel was not a common thief, and he reflected.
It was not yet certain, although very probable, that the tulip would flower black; if, therefore, he stole it now, he not only might be committing a useless crime, but also the theft might be discovered in the time which must elapse until the flower should open.
He, therefore—as, being in possession of the key, he might enter Rosa’s chamber whenever he liked—thought it better to wait and to take it either an hour before or after opening, and to start on the instant to Haarlem, where the tulip would be before the judges of the committee before any one else could put in a reclamation.
