“I’m very glad you had Mr. Garnesk with you,” said Dennis at last, with a glance of frank admiration at the young specialist.

“Not so glad as I am,” I replied fervently. “What I should have done without him heaven only knows. I can’t even guess.”

“Oh, nonsense!” cried Garnesk, in modest protest. “I haven’t been able to do anything. Our one advance was a piece of pure luck—the discovery that Miss McLeod could see by the light of a red lamp. We have decided to keep that quite to ourselves, Mr. Burnham.”

“Of course,” agreed Dennis, so emphatically that I laughed.

“Why so decided, Den?” I asked, for I felt that I should like to climb to the topmost pinnacle of the highest peak in all the world and shout the good news to the four corners of the earth.

“I’m not a scientist, Ron,” Dennis replied. “That may account for the heresy of my profound disbelief in science. I wouldn’t cross the road to see a ‘miracle.’ The twentieth century is uncongenial to anything of that sort. Take it from me, old chap, there’s a man at the back of this—not a nice man, I admit, but an ordinary human being to all outward appearances—and when we catch a glimpse of his outward appearances we shall know what to do.”

“Yes, when we do,” I sighed.

“You mustn’t let Ewart get depressed about things, Mr. Burnham. He very naturally looks at this business from a different standpoint. With him it is a tragic, mysterious horror, which threatens the well-being, if not the existence, of a life that is dearer to him than his own.”

“I’ll look after him,” said Dennis, with a grim determination which made even Garnesk laugh.
