to remain so as long as ever this goes on—probably for life. She will not give me her confidence. What is more, I am certain that she is giving it to Esther Mawson—who is most likely hand-in-glove with Pratt. Esther Mawson is always with her. I am almost sure that she communicates with Pratt through Esther Mawson. It is all what I say—intolerable! I had rather lose every penny that has come into my hands than have this go on."
"Answer me a plain question," said Collingwood. "Is your mother fond of money, position—all that sort of thing?"
"She is fond of power!" replied Nesta. "It pleased her greatly when we came into all this wealth to know that she was the virtual administrator. Even if she could only do it by collusion with Pratt, she would make a fight for all that she—and I—hold. It's useless to deny that. Don't forget," she added, looking appealingly at Collingwood, "don't forget that she has known what it was to be poor—and if one does come into money—I suppose one doesn't want to lose it again."
"Oh, it's natural enough!" agreed Collingwood. "But—if things are as I think, Pratt would be an incubus, a mill-stone, for ever. Anyway, I came out to tell you what I've learned, and what I have an idea may be the truth, and above all, to get your definite opinion. You want the Pratt influence out of the way—at any cost?"
"At any cost!" she affirmed. "Even if I have to go back to earning my own living! Whatever pleasure in life could there be for me, knowing that at the back of all this there is that—what?"
"Pratt!" answered Collingwood. "Pratt! He's the shadow—with his deep schemes. However, as I said—there may be—developing at this moment—another way of getting at Pratt. Gentlemen like Pratt, born schemers, invariably forget one very important factor in life—the unexpected! Even the cleverest and most subtle schemer may have his delicate machinery broken to pieces by a chance bit of mere dust getting into it at an unexpected turn of the wheels. And to turn to plainer language—I'm going back to Barford now to hear what another man has to say concerning certain of Pratt's recent movements."
Eldrick was already waiting when Collingwood reached his chambers: Byner came there a few moments later. Within half an hour the barrister had told his story of Cobcroft, and the inquiry agent his of his visit to the Green Man and the quarries. And the solicitor listened quietly and attentively to both, and in the end turned to Collingwood.
"I'll withdraw my opinion about the nature of the document which Pratt got hold of," he said. "What he's got is what you think—John Mallathorpe's will!"
"If I may venture an opinion," remarked Byner, "that's dead certain!"
"And now," continued Eldrick, "we're faced with a nice situation! Don't either of you forget this fact. Not out of willingness on her part, but because she's got to do it, Mrs. Mallathorpe and Pratt are partners in that affair. He's got the will—but she knows its contents. She'll pay any price to Pratt to keep them from ever becoming known or operative. But, as I say, don't you forget something!"
"What?" asked Collingwood.
Eldrick tapped the edge of the table, emphasizing his words as he spoke them.
"They can destroy that will whenever they like!" he said. "And once destroyed, nothing can absolutely prove that it ever existed!"
"The duplicate?" suggested Collingwood.
"Nothing to give us the faintest idea as to its existence!" said Eldrick.
"We might advertise," said Collingwood.
"Lots of advertising was done when John Mallathorpe died," replied the solicitor. "No!—if any person had had it in possession, it would have turned up then. It may be—probably is—possibly must be—somewhere—and may yet come to light. But—there's another way of getting at Pratt. Through this Parrawhite affair. Pratt most likely had not the least notion that he would ever hear of Parrawhite again. He is going to hear of Parrawhite again! I am convinced now that Parrawhite knew something about this, and that Pratt squared him and got him away. Aren't you?" he asked, turning to Byner.
But Byner smiled quietly and shook his head.
"No!" he answered. "I am not, Mr. Eldrick."
"You're not?" exclaimed Eldrick, surprised and wondering that anybody could fail to agree with him.
"Why not, then?"
"Because," replied Byner. "I am certain that Pratt murdered Parrawhite on the night of November twenty-third last. That's why. He didn't square him. He didn't get him away. He killed him!"
The effect of this straightforward pronouncement of opinion on the two men who heard it was strikingly different. Collingwood's face at once became cold and inscrutable; his lips fixed themselves sternly; his eyes looked hard into a problematic future. But Eldrick flushed as if a direct accusation had been levelled at himself, and he turned on the inquiry agent almost impatiently.
"Murder!" he exclaimed. "Oh, come! I—really, that's rather a stiff order! I dare say Pratt's been up to all sorts of trickery, and even deviltry—but murder is quite another thing. You're pretty ready to accuse him!"
Byner moved his head in Collingwood's direction—and Eldrick turned and looked anxiously at Collingwood, who, finding the eyes of both men on him, opened his hitherto tight-shut lips.
"I think it quite likely!" he said.
Byner laughed softly and looked at the solicitor.
"Just listen to me a minute or two, Mr. Eldrick," he said. "I'll sum up my own ideas on this matter, got from the various details that have been supplied to me since I came to Barford. Just consider my points one by one. Let's take them separately—and see how they fit in.
"1. Mr. Bartle is seen by his shop-boy to take a certain paper from a book which came from the late John Mallathorpe's office at Mallathorpe Mill. He puts that paper in his pocket.
"2. Immediately afterwards Mr. Bartle goes to your office. Nobody is there but Pratt—as far as Pratt knows.
"3. Bartle dies suddenly—after telling Pratt that the paper is John Mallathorpe's will. Pratt steals the will. And the probability is that Parrawhite, unknown to Pratt, was in that office, and saw him steal it. Why is that probable? Because—
"4. Next night Parrawhite, who is being pressed for money by Pickard, tells Pickard that he can get it out of Pratt, over whom he has a hold. What hold? We can imagine what hold. Anyway—
"5. Parrawhite leaves Pickard to meet Pratt. He did meet Pratt—in Stubbs' Lane. He was seen to go with Pratt into the disused quarry. And there, in my opinion, Pratt killed him—and disposed of his body.
"6. What does Pratt do next? He goes to your office first thing next morning, and removes certain moneys which you say you carelessly left in your desk the night before, and tears out certain cheque forms from your book. When Parrawhite never turns up that morning, you—and Pratt—conclude that he's the thief, and that he's run away.
"7. If you want some proof of the correctness of this last suggestion, you'll find it in the fact that no use has ever been made of those blank cheques, and that—in all probability—the stolen bank-notes have never reached the Bank of England. On that last point I'm making inquiry—but my feeling is that Pratt destroyed both cheques and bank-notes when he stole them.
"8. This man Parrawhite out of the way, Pratt has a clear field. He's got the will. He's already acquainted Mrs.
