"There is something about that that I cannot understand," replied Edwards. "From what Pearson told me, there must have been more than twenty thousand dollars in the vault, twelve thousand of which was in gold. The agreement was that Duncan, Pearson and myself were to have six thousand dollars apiece, and the balance was to be paid to Johnson for his silence. Pearson took his share out on the Saturday before the robbery, and when Duncan and I came to divide the money, we found that we were five thousand dollars short. There is only one solution I have to give for this, and that is that Pearson did not act fair with us, and took five thousand dollars in gold more than he was to have done." "Where did you and Duncan separate after the robbery?" asked William. "At Clinton, Iowa," was the reply. "Duncan went on toward Des Moines, while I made my way east, where I remained until you found me." Upon being questioned further, Edwards stated that when he met Duncan, he had a room in the lower part of the city, with a very respectable lady, who rented furnished apartments, and that when he left the city, having no money, he left his trunk and baggage in his room until he could settle for his rent. This was all that could be gained from Edwards at this time, and it must be confessed was most important. Pearson's guilt was fully proven, and we had a strong clew as to the identity of the third man in the robbery. It is true that he had more than a month the start of us, but we did not despair of finding him at last. In the meantime, much was to be speedily done. Edwards must be conveyed to Geneva at once, Johnson must be arrested at St. Louis, and we must pay our respects to Eugene Pearson as soon as possible. We must also start immediately upon the track of Thomas Duncan, and endeavor to trace him to his hiding-place. Everything was therefore made ready for the departure of Edwards, who was consigned to the care of two trusty operatives until evening, when they would take him to Geneva; and William forwarded a telegraphic message to Mr. Silby, at Geneva, to this effect: "WATCH THAT PACKAGE." CHAPTER XIII. Edwards Taken to Geneva--The Arrest of Eugene Pearson--His Confession--More Money Recovered--Dr. Johnson Arrested. As may be imagined, our detective labors were now but fairly commenced. We had, it is true, succeeded in capturing one of the active participants in the robbery, and in securing nearly four thousand dollars of the money that had been taken. We had also obtained information which would enable us to arrest two more of the parties who were connected with the affair, and perhaps secure an additional sum of money. The information which Edwards had given, however, was of vast importance to us, and enabled us to pursue our further search with a more intelligent knowledge of the parties interested, and with a more reasonable hope of eventual success.
