Alf and Bill, on the other hand, were not a little disturbed. They had realized at once that Eustace, in his ignorance, had committed an awful social solecism. Even the resourceful Bill's imagination boggled at the idea of explaining to this dainty vision how she came to be in her present surroundings. They stood before her, embarrassed and tongue-tied. Alf thought of recalling the djinn and telling him to take her straight back; but his very real and increasing fear of offending his familiar forbade. Besides, his visitor was very lovely, and filled his jaded masculine eye with a lively sense of satisfaction.

After a while the silence became oppressive and Isobel spoke.

"Where am I?" she asked. "Who are you?"

Bill, who had been making a surreptitious and feline toilet in the gloomy recesses of the dug-out, stepped forward and saluted.

"Don't be frightened, miss," he said soothingly, "but this 'ere's a dug-out in France, on the Western Front."

"That proves it," said Isobel to herself, with a certain satisfaction. "It is just a vivid dream. Perhaps it's telepathy or levitation or something. Anyway, the great point to remember is that I'm not really here at all."

The two men watched her anxiously. Both had expected her to be terrified at the news. Her air of unruffled serenity alarmed them, because neither could understand it.

"Now let me see," she continued her train of thought—"a few minutes ago, I was in the Park with Peggy—but perhaps I dreamt that, too. In fact I must have.... I don't remember going to bed, though.... Oh, well, it's no good worrying, it'll be all right when I wake up. A dug-out?" She echoed Bill's words uncertainly.

"Yes, miss. I'm very sorry, miss. If you please, it's all a mistake. We didn't mean no 'arm. If you'll just wait a minute, we'll send you back again to London quite all...."

But Isobel's usual spirit returned to her at this point. Whether this was dream or miracle, she determined to see it through.
