"Yes, that's she," he replied, "and that's Northrop with her—the man that Mallalieu was playing cards with last night. She's governess to Northrop's two younger children—I expect she's heard about her father, and has been to get Northrop to come down with her—he's a magistrate."

Avice listened with ill-concealed impatience while Bent delivered his message. He twice repeated Harborough's injunction that she was not to be afraid, and her impatience increased.

"I'm not afraid," she answered. "That is, afraid of nothing but my father's obstinacy! I know him. And I know that if he's said he won't tell anything about his whereabouts last night, he won't! And if you want to help him—as you seem to do—you must recognize that."

"Wouldn't he tell you?" suggested Brereton.

The girl shook her head.

"Once or twice a year," she answered, "he goes away for a night, like that, and I never know—never have known—where he goes. There's some mystery about it—I know there is. He won't tell—he'll let things go to the last, and even then he won't tell. You won't be able to help him that way—there's only one way you can help."

"What way?" asked Bent.

"Find the murderer!" exclaimed Avice with a quick flash of her eyes in Brereton's direction. "My father is as innocent as I am—find the man who did it and clear him that way. Don't wait for what these police people do—they'll waste time over my father. Do something! They're all on the wrong track—let somebody get on the right one!"

"She's right!" said Northrop, a shrewd-faced little man, who looked genuinely disturbed. "You know what police are, Mr. Bent—if they get hold of one notion they're deaf to all others. While they're concentrating on Harborough, you know, the real man'll be going free—laughing in his sleeve, very like."

"But—what are we to do?" asked Bent. "What are we to start on?"
