So it was about the wreck Bob had come to speak. What more painful news could he have to bring than they already knew? The boy's common sense told him that the details must have to do with the death of Aunt Dorothy; nothing of less importance could have brought Bob over. Perhaps he had met an eye-witness of the tragedy! Perhaps there were last messages from the drowned girl!

Eustace turned a corner and came to an abrupt standstill. It seemed to him in that instant as if his very heart stopped beating and his hair stood straight on end.

It was absurd, of course. Bob had turned out to be no mere creation of his own brain, but this could be nothing else. Here was proof positive of Mr. Orban's words that one has but to think hard enough about a person to imagine one sees him.

With her back to the outer door—a white figure with a face as colourless as her dress—stood Dorothy Chase; nothing about her was lifelike except the familiar deep-brown eyes that gazed steadfastly on the startled boy.

It was an extraordinarily vivid hallucination, and not a little terrifying. Was it no fancy? Could it possibly be Aunt Dorothy's spirit come to visit her old home again? The thought leapt into the boy's mind.

Eustace was no coward, but the notion fairly paralyzed him; he could not have moved to save his life. One supreme effort he made.

"Aunt Dorothy," he whispered hoarsely, and could say no more, for his lips were parched, his throat was dry.

The vision raised a warning hand.

"Hush!" she said; "don't be frightened. I see Bob has not told you yet; but it is all right, darling. I am a real live human being, and no spirit. Just Aunt Dorothy come back to you safe and sound."

The words seemed to come from far away, and Eustace felt so queer he swayed to try and keep his balance. He was so giddy he must have fallen had the vision not swept forward and caught him. The feeling of those strong arms about him, the warm touch of Aunt Dorothy's face bent down to his, brought him with a jerk to himself again, and he did not faint. But even then he could not believe his senses.
