Taking in all this at a glance, Kenneth peered through the open door on the left. The room was dark and untenanted. He beckoned to his companions. They followed him into the room. In less than a minute the woman returned from the garden, closed and bolted the door, and was moving along the lobby when the stairs creaked slightly, and an old man came tottering down.
"Bier, noch Bier," he said in low tones to the woman.
The woman muttered something, took the lamp from its place, and accompanied by the old man went into one of the rooms off the lobby on the opposite side from the three watchers. They were heard clumping down wooden steps, no doubt leading to the cellars.
"Now's our chance," Kenneth whispered.
The three stole out of the room into the dark lobby, and crept on hands and knees up the staircase. The landing above was equally dark, except in the far corner on the right, where light came through a door slightly ajar. The three men tiptoed to it. Kenneth peeped in. The room was apparently Obernai's bedroom. No one was in it; the bed had not been disturbed. A candle was burning on the dressing-table. Pieces of heavy French furniture afforded means of concealment.
"You stay here," whispered Kenneth. "I'll go on."
He slipped off his boots, blew out the candle, and crept out. There was no sound from below. On the opposite side of the landing was a narrow staircase, leading, he presumed, to the attics. Up this he groped his way. At the top there was a passage, at the end of which, on the right, was a streak of light on the floor. Feeling his way along, he felt two other doors, the handles of which he turned in succession, hoping to slip into a dark room as he had done below. Both doors were locked. At this moment, hearing the footsteps of the old man coming slowly up the bottom flight of stairs, he slipped back to the dark end of the passage and stood watching there.
The old man mounted the upper flight. A can clinked against the post as he turned to the right towards the door beneath which the light shone. He tapped on the door; it was opened; the man passed in. Kenneth heard a guttural voice say: "Zwei Batterien heute morgen----" The remainder of the sentence was cut off by the closing of the door. In a few moments it opened again; the old man came out, closed it behind him, and sat down on a stool at the end of the passage, either as sentry, or to be at hand if more beer was required.
Kenneth scarcely dared to breathe. What was going on in that room? What could he do? After several uncomfortable minutes the door suddenly opened--too wide for his comfort--and a voice said:
"Frisch auf! Die Lampe ist beinahe erlöscht."
