"In such an old castle," continued the Prince, "there are many doors that few know--perhaps also passages in the wall. Whether it is spirits or something else, who knows? It glides about and sometimes comes out when one least expects it; and just when one has put on one's night-shirt a secret door is opened, or a plank in the floor rises, and a cursed apparition floats up, removes what is on the table, and before one can bethink oneself, disappears again."

"Who can allow such a thing, your Highness?" replied Gabriel, valiantly.

"Who can be on his guard?" said the Prince, laughing; "it stretches out its hand, and one becomes immovable; it holds a sponge before the nose of the sleeper and he does not awake."

Gabriel listened attentively.

"People say that in the Pavilion all is not secure," continued the Prince. "It would be as well for a trusty man to make an examination in secret; and if an entrance should be found that is not regular it should be fastened with a screw or a bolt. It is indeed uncertain whether or not one may find such a thing, for such devil's work is slyly managed."

He nodded significantly to Gabriel, who stared at him in great astonishment.

"That is only a thought of mine," said the Prince; "but when a soldier is in foreign quarters he looks after every security during the time that his people sleep."

"I understand all," replied Gabriel, in a low voice.

"One must not cause others unnecessary alarm," continued the Prince; "but in secret one may do one's duty like a brave man. I see you are that." The Prince rose from his seat. "If you should at any time need my help, or have anything to tell me which no one else should know, I have a fellow with a great moustache, a good, quiet man; make his acquaintance. For the rest, take care of yourselves here. There is a lackey who idles about near you; if there are any errands to do he can attend to them. It is a good thing for a family to have a trustworthy man at hand in a strange house. Good day, comrade, I hope I have changed the current of your thoughts."

He went away; Gabriel remained in deep thought. The bantering of the Prince had roused the honest man from his sorrow; he busied himself now about the house in the day-time, but in the evening, when his master and mistress were at the theatre, he was to be seen sometimes with the Prince's servant in confidential conversation on a garden bench.
