"I agree with you wholly," added Judge Key. "Besides, this fellow, Bernardi, knows nothing of the Don's forgeries and frauds except those committed in Peru, and as we have before shown, we could make no use of those accusations until we hear from Peru. Indeed, it is questionable how far we can proceed even then, for we have no extradition treaty with that country." "Well, I do not mind that very much," I replied, "for my chief dependence is upon the moral effect upon Don Pedro. I think that we can so work upon him as to obtain his consent to go to Peru voluntarily, rather than to be detained here until a requisition arrives from England. He knows that if he be sent to England, he will be transported for a long term of years; whereas, in Peru, he may avoid conviction altogether, or purchase his escape after conviction." "But can we make him give up his plunder?" asked the Senator, anxiously. "I think we can," said I. "You see that he is liable to be held here for obtaining money under false pretenses, and during the trial the money could be taken by attachment. Then, even though he should not be convicted, the delay would enable us to make sure of sending him back to London, where a heavy sentence would undoubtedly be given him. Now, by representing these things to him, we shall induce him to hand over the money voluntarily, and after that we shall not care whether he is taken to Great Britain or Peru." "If that be the case, why not arrest him now and get the advices from London afterward?" asked the Senator, who was very anxious to hasten matters. "Because we could not present a sufficient case to hold him under the preliminary examination," replied Judge Key. "When we get official news of the fellow's character from Peru, we shall have a sure thing against him, and then I shall feel ready to act; but I agree with Mr. Pinkerton that there would be danger in overhaste. You see, we have him carefully watched, and there is no probability that he intends to make off until after this _fête champêtre_; therefore, let us wait for our foreign advices as long as we can, and in case he prepares to go before they arrive, it will be time enough to arrest him then." "How about the Donna?" asked Muirhead. "Do you propose to take any steps against her?" "I don't see how we can," I replied. "With the exception of the sums she has received from Mather, she has obtained nothing fraudulently; and, as you may well suppose, we could never get Mather to testify against her; so I guess we need not trouble ourselves to interfere with the lovely Donna at all." Our conference then broke up with the understanding that we should assemble again the moment any new facts in the case should be developed. Just after the gentlemen had left, Madame Sevier came in and reported a scene between Mather and the Donna which had taken place the previous evening.
