Once more, Allan was at a loss for an answer; and, once more, Midwinter’s ready memory helped him through the difficulty.

“I think I can trace our way back to this impression, as I traced our way back to the other,” he said, addressing the doctor. “After we got here yesterday afternoon, my friend and I took a long walk over the hills—”

“That’s it!” interposed Allan. “I remember. The sun was setting as we came back to the hotel for supper, and it was such a splendid red sky, we both stopped to look at it. And then we talked about Mr. Brock, and wondered how far he had got on his journey home. My memory may be a slow one at starting, doctor; but when it’s once set going, stop it if you can! I haven’t half done yet.”

“Wait one minute, in mercy to Mr. Midwinter’s memory and mine,” said the doctor. “We have traced back to your waking impressions the vision of the open country, the pool, and the sunset. But the Shadow of the Woman has not been accounted for yet. Can you find us the original of this mysterious figure in the dream landscape?”

Allan relapsed into his former perplexity, and Midwinter waited for what was to come, with his eyes fixed in breathless interest on the doctor’s face. For the first time there was unbroken silence in the room. Mr. Hawbury looked interrogatively from Allan to Allan’s friend. Neither of them answered him. Between the shadow and the shadow’s substance there was a great gulf of mystery, impenetrable alike to all three of them.

“Patience,” said the doctor, composedly. “Let us leave the figure by the pool for the present and try if we can’t pick her up again as we go on. Allow me to observe, Mr. Midwinter, that it is not very easy to identify a shadow; but we won’t despair. This impalpable lady of the lake may take some consistency when we next meet with her.”

Midwinter made no reply. From that moment his interest in the inquiry began to flag.

“What is the next scene in the dream?” pursued Mr. Hawbury, referring to the manuscript. “Mr. Armadale finds himself in a room. He is standing before a long window opening on a lawn and flower-garden, and the rain is pattering against the glass. The only thing he sees in the room is a little statue; and the only company he has is the Shadow of a Man standing opposite to him. The Shadow stretches out its arm, and the statue falls in fragments on the floor; and the dreamer, in anger and distress at the catastrophe (observe, gentlemen, that here the sleeper’s reasoning faculty wakes up a little, and the dream passes rationally, for a moment, from cause to effect), stoops to look at the broken pieces. When he looks up again, the scene has vanished. That is to say, in the ebb and flow of sleep, it is the turn of the flow now, and the brain rests a little. What’s the matter, Mr. Armadale? Has that restive memory of yours run away with you again?”

“Yes,” said Allan. “I’m off at full gallop. I’ve run the broken statue to earth; it’s nothing more nor less than a china shepherdess I knocked off the mantel-piece in the hotel coffee-room, when I rang the bell for supper last night. I say, how well we get on; don’t we? It’s like guessing a riddle. Now, then, Midwinter! your turn next.”

“No!” said the doctor. “My turn, if you please. I claim the long window, the garden, and the lawn, as my property. You will find the long window, Mr. Armadale, in the next room. If you look out, you’ll see the garden and lawn in front of it; and, if you’ll exert that wonderful memory of yours, you will recollect that you were good enough to take special and complimentary notice of my smart French window and my neat garden, when I drove you and your friend to Port St. Mary yesterday.”
