'Old servants are proverbial for their long memories,' the clerkly visitor went on. 'Are there any such remaining in his old home who would know anything about the man? Even a birth-mark--although it is a thing most often connected with cheap romances nowadays--might help to establish a case.' 'Or disestablish it,' said Peter. 'Or disestablish it,' repeated the echo. 'As a matter of fact,' Peter said, relenting a little, 'the child was born abroad, and no evidence of that sort is forthcoming. The lawyers have followed every possible clue that could lead to information about him without any result whatever.' 'Singular!' said Purvis. 'Yes,' assented Peter, 'I suppose there are few cases in which a man has disappeared so completely, and left no trace behind him.' 'The property which is at stake is a large one, I understood you to say,' said Purvis. 'I don't think I said so,' Peter answered; 'but there is no harm in telling you that some money is involved.' 'I should certainly know if any considerable property had been willed away about here,' said Purvis quietly; 'and you see our richest men in camp have really not much else except landed property to leave. In Buenos Ayres, and Rosario too, a man of importance in the town dying and leaving money could easily be traced.' 'Well, I haven't exactly expectations from him,' said Peter, feeling that he was getting into a muddle. 'The fact is,' he said cordially, 'I shall be interested to hear news of the man if you can obtain any for me.' So far he had always regarded his brother's existence as some remote and hardly possible contingency. Now he began to see plainly that the man might very possibly be alive, and not only so, but that it might also be possible to trace his whereabouts. The sudden realization of this staggered him for a moment; but he went on steadily, 'I want the man found, and I shall spare no trouble or expense in finding him. Even if he is dead I do not mind telling you that any definite information would be welcome to me; and if he is alive my object is to find him as soon as possible.' Mr. Purvis took out his pocket-book. 'You will at least know whether the man was dark or fair?' he said. 'Fair, I suppose,' said Peter; 'all the portraits in the house are of fair men.' 'The man I spoke of is dark,' said Purvis, continuing his jottings in his notebook in a neat hand. 'Fair children often get dark as they grow older,' said Peter. Purvis acquiesced. 'The singular thing about it all is,' he said, 'that no one now seems to be living who saw the boy when he was a baby.' 'No one can be traced,' said Peter. 'This affair of the child in Rosario is probably a mare's nest,' said Mr. Purvis in his hopeless way, as he closed his pocket-book and put a strap round it.
