Nesta, left alone, gave herself up to deep thought, and to a careful reckoning of her position. She was longing to confide in some trustworthy person or persons, for Pratt's revelations had plunged her into a maze of perplexity. But her difficulties were many. First of all, she would have to tell all about the terrible charge brought by Pratt against her mother. Then about the second which he professed to—or probably did—hold. What sort of a secret could it be? And supposing her advisers suggested strong measures against Pratt—what then, about the danger to her mother, in a twofold direction?

Would it be better, wiser, if she kept all this to herself at present, and waited for events to develop? But at the mere thought of that, she shrank, feeling mentally and physically afraid—to keep all that knowledge to herself, to brood over it in secret, to wonder what it all meant, what lay beneath, what might develop, that was more than she felt able to bear. And when Eldrick came back she looked at him and nodded.

"I should like to talk to you and Mr. Collingwood," she said quietly.

Collingwood came across to Eldrick's office at once. And to these two Nesta unbosomed herself of every detail that she could remember of her interview with Pratt—and as she went on, from one thing to another, she saw the men's faces grow graver and graver, and realized that this was a more anxious matter than she had thought.

"That's all," she said in the end. "I don't think I've forgotten anything. And even now, I don't know if I've done right to tell you all this. But—I don't think I could have faced it—alone!"

"My dear Miss Mallathorpe!" said Eldrick earnestly. "You've done the wisest thing you probably ever did in your life! Now," he went on, looking at Collingwood, "just let us all three realize what is to me a more important fact. Nobody would be more astonished than Pratt to know that you have taken the wise step you have. You agree, Collingwood?"

"Yes!" answered Collingwood, after a moment's reflection. "I think so."

"Miss Mallathorpe doesn't quite see what we mean," said Eldrick, turning to Nesta. "We mean that Pratt firmly believed, when he told you what he did, that for your mother's sake and your own, you would keep his communication a dead secret. He firmly believed that you would never dare to tell anybody what he told you. Most people—in your position—wouldn't have told. They'd have let the secret eat their lives out. You're a wise and a sensible young woman! And the thing is—we must let Pratt remain under the impression that you are keeping your knowledge to yourself. Let him continue to believe that you'll remain silent under fear. And let us meet his secret policy with a secret strategy of our own!"

Again he glanced at Collingwood, and again Collingwood nodded assent.

"Now," continued Eldrick, "just let us consider matters for a few minutes from the position which has newly arisen. To begin with. Pratt's account of your mother's dealings about the foot-bridge is a very clever and plausible one. I can see quite well that it has caused you great pain; so before I go any further, just let me say this to you—don't you attach one word of importance to it!"
