Drummond waited for her to compose herself before he spoke again. “You mentioned murder, too,” he remarked.

She nodded. “I’ve got no proof,” she said, “less even than over the burglaries. But there was a man called George Dringer, and one evening, when Lakington was dining with us, I heard him discussing this man with Daddy.

“‘He’s got to go,’ said Lakington. ‘He’s dangerous!’

“And then my father got up and closed the door; but I heard them arguing for half an hour. Three weeks later a coroner’s jury found that George Dringer had committed suicide while temporarily insane. The same evening Daddy, for the first time in his life, went to bed the worse for drink.”

The girl fell silent, and Drummond stared at the orchestra with troubled eyes. Things seemed to be rather deeper than he had anticipated.

“Then there was another case.” She was speaking again. “Do you remember that man who was found dead in a railway-carriage at Oxhey station? He was an Italian—Giuseppe by name; and the jury brought in a verdict of death from natural causes. A month before, he had an interview with Lakington which took place at our house: because the Italian, being a stranger, came to the wrong place, and Lakington happened to be with us at the time. The interview finished with a fearful quarrel.” She turned to Drummond with a slight smile. “Not much evidence, is there? Only I know Lakington murdered him. I know it. You may think I’m fanciful—imagining things; you may think I’m exaggerating. I don’t mind if you do—because you won’t for long.”

Drummond did not answer immediately. Against his saner judgment he was beginning to be profoundly impressed, and, at the moment, he did not quite know what to say. That the girl herself firmly believed in what she was telling him, he was certain; the point was how much of it was—as she herself expressed it—fanciful imagination.

“What about this other man?” he asked at length.

“I can tell you very little about him,” she answered. “He came to The Elms—that is the name of Lakington’s house—three months ago. He is about medium height and rather thick-set; clean-shaven, with thick brown hair flecked slightly with white. His forehead is broad, and his eyes are a sort of cold grey-blue. But it’s his hands that terrify me. They’re large and white and utterly ruthless.” She turned to him appealingly. “Oh! don’t think I’m talking wildly,” she implored. “He frightens me to death—that man: far, far worse than Lakington. He would stop at nothing to gain his ends, and even Lakington himself knows that Mr. Peterson is his master.”

“Peterson!” murmured Drummond. “It seems quite a sound old English name.”
