"What do you want with him?" she demanded fiercely. "He knows nothing about it. How should he? What is it to do with him?"
The men looked at her with quick interest. But Layton silenced her with an imperative gesture.
"I am at your service," he said quietly. "What can I do for you?"
"We are instructed to ask you to be kind enough to return with us to Scotland Yard to answer a few questions that may assist the investigation of the crime."
"Certainly," Layton returned, without hesitation.
His face was perfectly calm. He showed no fear or agitation.
"We have a taxi waiting," the man said. He spoke to Layton—but he was looking at the girl.
"I will come with you at once," Layton replied.
He took up his hat and stick. The girl leant against the wall panting, a hand pressed to her heart.
