"But Martin knows that you have been here," I protested, my mind in a whirl at this sudden turn of affairs; "and the man sitting on the bench outside must have seen you come in also."

It was on the tip of my tongue to say, "Neither do I," but:

I could hear Martin, the landlord, talking to the Eurasian doctor in the passage outside the coffee-room, and before I had time to open the door, there came a peremptory rap, the door was opened from the outside and Dr. Damar Greefe entered.

In spite of the already great heat of the morning he wore a heavy black overcoat, and his white hair showed in startling relief beneath a wide-brimmed black felt hat.
