"Frankly--these, or something like these," replied Collingwood. "And I get at my conclusions in this way. Your uncle died intestate--consequently, everything in the shape of real estate came to your brother and everything in personal property to your brother and yourself. Now, supposing that the document which Pratt boasts of holding is the will, one fact is very certain--the property, real or personal, is not disposed of in the way in which it became disposed of because of John Mallathorpe's intestacy. He probably disposed of it in quite another fashion. Why do I think that? Because the probability is that Pratt said to your mother, 'I have got John Mallathorpe's will! It doesn't leave his property to your son and daughter. Therefore, I have all of you at my mercy. Make it worth my while, or I will bring the will forward.' Do you see that situation?" "Then," replied Nesta, after a moment's reflection, "you do think that my mother was very anxious to get that document--a will--from Pratt?" Collingwood knew what she was thinking of--her mind was still uneasy about Pratt's account of the affair of the foot-bridge. But--the matter had to be faced. "I think your mother would naturally be very anxious to secure such a document," he said. "You must remember that according to Pratt's story to you, she tried to buy it from him--just as you did yourself, though you, of course, had no idea of what it was you wanted to buy." "What I wanted to buy," she answered readily, "was necessity from further interference! But--is there no way of compelling Pratt to give up that document--whatever it is? Can't he be made to give it up?" "A way is may be being made, just now--through another affair," replied Collingwood. "At present matters are vague. One couldn't go to Pratt and demand something at which one is, after all, only guessing. Your mother, of course, would deny that she knows what it is that Pratt holds. But--there is the possibility of the duplicate to which Cobcroft referred. Now, I want to put the question straight to you--supposing that duplicate will can be found--and supposing--to put it plainly---its terms dispossess you of all your considerable property--what then?" "Do you want the exact truth?" she asked. "Well, then, I should just welcome anything that cleared up all this mystery! What is it at present, this situation, but intolerable? I know that my mother is in Pratt's power, and likely 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?"
