At eleven o'clock Gryphus was dead drunk. At two in the morning Boxtel saw Rosa leaving the chamber; but evidently she held in her arms something which she carried with great care.
He did not doubt that this was the black tulip which was in flower.
But what was she going to do with it? Would she set out that instant to Haarlem with it?
It was not possible that a young girl should undertake such a journey alone during the night.
Was she only going to show the tulip to Cornelius? This was more likely.
He followed Rosa in his stocking feet, walking on tiptoe.
He saw her approach the grated window. He heard her calling Cornelius. By the light of the dark lantern he saw the tulip open, and black as the night in which he was hidden.
He heard the plan concerted between Cornelius and Rosa to send a messenger to Haarlem. He saw the lips of the lovers meet, and then heard Cornelius send Rosa away.
He saw Rosa extinguish the light and return to her chamber. Ten minutes after, he saw her leave the room again, and lock it twice.
Boxtel, who saw all this whilst hiding himself on the landing-place of the staircase above, descended step by step from his story as Rosa descended from hers; so that, when she touched with her light foot the lowest step of the staircase, Boxtel touched with a still lighter hand the lock of Rosa's chamber.
And in that hand, it must be understood, he held the false key which opened Rosa's door as easily as did the real one.
And this is why, in the beginning of the chapter, we said that the poor young people were in great need of the protection of God.
