“Well,” I asked, at last, “what now?”

“We must see if Swain has returned,” he answered.  “If he has, all right.  If he hasn’t, we’ll have to go and look for him.”

“What is it you fear, Godfrey?” I demanded.  “Do you think Swain’s in danger?”

“I don’t know what I fear; but there’s something wrong over there.  This is the first night for a week that that light hasn’t appeared.”

“Still,” I pointed out, “that may have nothing to do with Swain.”

“No; but it’s a coincidence that he should be in the grounds—­and I’m always afraid of coincidences.  Let us see if he is back,” and he turned toward the house.

But I held his arm.

“If he’s back,” I said, “he’ll have taken the ladders down from the wall.”

“That’s true,” and together we made our way forward among the trees.  Then we reached the wall, and there was the dim white line of the ladder leaning against it.  Without a word, Godfrey mounted it, stood an instant at the top, and then came down again.

“The other ladder is still there,” he said, and took off his cap and rubbed his head perplexedly.  I could not see his face, but I could guess how tense it was.  I had been with him in many trying situations, but only once before had I seen him use that gesture!

“It won’t do to alarm the house,” he said, at last.  “Do you know where he was to meet Miss Vaughan?”

“At an arbour in one corner of the grounds,” I answered.

“Then we’ll start from there and take a quiet look for him.  Wait here for me a minute.”

He melted into the darkness, and I stood holding on to the ladder as though in danger of falling, and staring at the top of the wall, where I had last seen Swain.  An hour and a half had passed since then....

A touch on the arm brought me around with a start.

“Here, put this pistol in your pocket,” said Godfrey’s voice, and I felt the weapon pressed into my hand.  “And here’s an electric torch.  Do you feel the button?”

“Yes,” I said, and pressed it.  A ray of light shot toward the wall, but I released the button instantly.

“You’d better keep it in your hand,” he added, “ready for action.  No telling what we’ll run across.  And now come ahead.”

He put his foot on the ladder, but I stopped him.

“Look here, Godfrey,” I said, “do you realise that what we’re about to do is pretty serious?  Swain might have a legal excuse, since the daughter of the house invited him to a meeting; but if we go over the wall, we’re trespassers pure and simple.  Anybody who runs across us in the darkness has the right to shoot us down without asking any questions—­and we’d have no legal right to shoot back!”

I could hear Godfrey chuckling, and I felt my cheeks redden.

“You remind me of Tartarin,” he said; “the adventurer-Tartarin urging you on, the lawyer-Tartarin holding you back.  My advice is to shake the lawyer, Lester.  He’s out of his element here to-night.  But if he’s too strong for you, why, stay here,” and he started up the ladder.
