I saw the reason for the caution. The hill on which we stood faced the gate in the rear of the house, and as Mr. Rivers laid hold of me and whispered in my ear, this gate was slowly opened and a form issued from it. I could not at that distance distinguish whether it was the form of a man or a woman; what I could distinguish was that the figure paused a moment or two and seemed to peer within the grounds. Then, closing the gate with an appearance of caution, the figure came into the open, and limped away.
"Step softly," whispered Mr. Rivers, and taking me by the hand we followed the figure, which we presently discerned to be that of an old woman, who walked as if she were lame. I stepped almost as softly as my companion, and we succeeded in approaching close to her without being observed. She was carrying something in her hands, covered with a white cloth. Night's shadows befriended us, and it was evident that the woman had no notion that she was being followed. Mr. Rivers did not speak, nor did I. We must have walked half a mile when the woman stopped before a wretched hut, which she entered without knocking.
"We must see what she's up to," whispered Mr. Rivers. "She belongs to Mr. Nisbet's house, and has crept away in secret. It is my opinion we're in luck."
Stealing round the hut we came to a window at the back over which there was no curtain, so that, although the glass was to some extent obscured by dust and mud, we could see what was passing within. On the ground lay a gaunt man, and by his side on a low stool sat a girl about twelve years of age, as nearly as I could judge. The girl had jumped up at the entrance of the old woman, but the man appeared to be too weak to raise himself. This was proved by the woman kneeling by him on one side and the girl kneeling by him on the other; by their united efforts they lifted him into a sitting posture, and then the woman removed the white cloth from the article she had carried from Mr. Nisbet's house; it was a large dish filled with food, and though she had come some distance the ascending steam proclaimed that it was still warm. The woman fed him with a spoon, and presently drew from a capacious pocket a bottle of red wine; he ate sparely, but he drank with avidity. When he had finished the girl partook of the food, and the eager way in which she ate reminded me of the night we found little Barbara in Lamb's Terrace. There was a pathos in the scene that touched me to the heart, but of course I could not hear what was said by the poor actors therein.
We waited till the old woman left the hut; she took the empty dish and the white cloth with her. When she came out we followed her back to Mr. Nisbet's house, which she entered by the back gate, adopting similar precautions to those which had marked her departure from it.
"A winning move," said Mr. Rivers in a tone of satisfaction as we retraced our steps to the Hôtel-Pension zur Tellsplatte.
"In what way?" I asked, for though I was impressed by what I had witnessed, I did not at the moment see in what way it could be turned to our advantage.
"The food and wine were stolen from Mr. Nisbet," replied Mr. Rivers, "and in that wretched hut we shall obtain the key to his house. We have done a good night's work."
During our absence Ronald and Bob had not been idle. By promising François pecuniary assistance to enable him to reach the paradise of waiters, they had won him completely over, and he had disclosed everything he knew relating to Mr. Nisbet's domestic affairs, and to the estimation in which he was held. He was not in favor, it appeared; he kept himself aloof from everybody in the place, and lived the life of an eccentric and a recluse. Reputed to be rich, he had not been known to do a single act of kindness to the poor peasantry in the district. There had been an explosion in a mine, there had been a conflagration, a neighboring village had been inundated, and he did not contribute a franc to the relief of the sufferers. Some people declared that he possessed "the evil eye," and that he could "will" misfortune upon those who offended him. As for his establishment, it consisted of himself, a young female, who was said to be daft, and an old woman who acted as cook and general housekeeper. The old woman's name was Bernstein, the young woman's was not known. She had not been seen for years outside the walls of the house. When Mr. Nisbet went away Mme. Bernstein was left in charge of the establishment, and neither then nor at any other time was any person admitted inside the grounds. Food and wine were taken in at the gates, by the master himself when he was at home, by Mme. Bernstein when he was absent. This was the sum total of the information which had been elicited from François.
After hearing this we related to Bob and Ronald our own adventure, and then we fell to discussing the next step to be taken, and Ronald urged that an endeavor should be made to obtain admission to the house.
