"Hullo! Is that Mr. Addison?" came Gatton's voice.
"Yes, speaking. What developments, Gatton?"
"Several. I've got the report of the estate-agent and I've seen the stage-doorkeeper of the New Avenue! You mustn't write anything until I see you, but in order to regularize things a bit I've spoken to the Chief and formally asked his permission to consult you on the case—about the Egyptian figures, you know. He remembered you at once, so it's all square. But I've got a bone to pick with you."
"What is that?"
"Never mind now. Can you meet me at the Red House at five o'clock?"
"Yes. I will be there."
"Good. I don't hope for much. It's the strangest case I ever touched. We are dealing with unusual people, not ordinary criminals."
"I agree."
"If there is any man in London who can see daylight through the mystery I believe you are the man. Do you know on what I think the whole thing turns?"
"On some undiscovered incident in Sir Marcus's past, beyond a doubt. Probably an amorous adventure."
