"Nobody?" she looked at him in astonishment. "But the doctor——"
"Not even the doctor," he said with a twinkle in his eye. "I ask you this as a special favour—word of honour?"
She thought a moment.
"I promise," she said. "I'm to tell nobody about that horrid man from whom you so kindly saved me——"
He lifted his head.
"Understand this, Miss Cresswell, please," he said: "I don't want you to be under any misapprehension about that 'horrid man'—he was just as scared as you, and he would not have harmed you. I have been waiting for him all the evening."
"Waiting for him?"
He nodded again.
"Where?"
"In the doctor's flat," he said calmly, "you see, the doctor and I are deadly rivals. We are rival scientists, and I was waiting for the hairy man to steal a march on him."
