At this cheerful point in my reminiscences I was suddenly interrupted by a sharp knock at the door.

CHAPTER V

AN OFFER WITHOUT AN ALTERNATIVE

With a big effort I pulled myself together. "Come in," I called out.

The door opened, and the girl, Sonia, entered the room. She was carrying a tray, which she set down on the top of the chest of drawers.

"I don't know the least how to thank you for all this," I said.

She turned round and looked at me curiously from under her dark eyebrows.

"For all what?" she asked.

"This," I repeated, waving my hand towards the tray, "and the hot bath last night, and incidentally my life. If it hadn't been for you and Dr. McMurtrie I think my 'career,' as the Daily Mail calls it, would be pretty well finished by now."

She stood where she was, her hand on her hip, her eyes fixed on my face.
