The Black Tulip

All this was detailed with an accent of truth which, although producing no change in the impassible mien of the Prince, did not fail to take effect on Van Systens.

"But," said the Prince, "it cannot be long since you knew the prisoner."

Rosa opened her large eyes and looked at the stranger, who drew back into the dark corner, as if he wished to escape her observation.

"Why, sir?" she asked him.

"Because it is not yet four months since the jailer Gryphus and his daughter were removed to Loewestein."

"That is true, sir."

"Otherwise, you must have solicited the transfer of your father, in order to be able to follow some prisoner who may have been transported from the Hague to Loewestein."

"Sir," said Rosa, blushing.

"Finish what you have to say," said William.

"I confess I knew the prisoner at the Hague."

"Happy prisoner!" said William, smiling.

At this moment the officer who had been sent for Boxtel returned, and announced to the Prince that the person whom he had been to fetch was following on his heels with his tulip.
