“Put up your hands,” said a voice sharply. “Or you're a dead man.”

He looked bewilderedly, taken altogether by surprise, and saw he was faced by a fat little man with a smooth, chubby, smiling face and eyes that were cold and grey and deadly, and who held in one hand a revolver levelled at his heart.

“Put up your hands,” this newcomer said again, his voice level and calm, his eyes intent and deadly. “Put up your hands or I fire.”
