The day after the robbery Evans had been at Bristol, Connecticut, in the interest of his firm, who, on receipt of the news, had immediately wired him to proceed to Northampton. His presence in Northampton was regarded as nothing strange, for he had been there several times during the months just preceding the robbery, and once had inspected the lock and dials of the vault of the robbed bank. What did seem a little strange, however, was Evans's evident interest in the negotiations for a compromise. On a dozen different occasions he talked with the president and other officers of the bank regarding the robbery, and insinuated quite plainly that he might be in a position to assist them in recovering their lost securities. A few months after the robbery he even went so far as to tell one of the directors that he could name the members of the gang. This disposition of Evans to put himself forward in the negotiations had all the more significance to Robert Pinkerton from the fact that it had been rumored that a series of daring bank robberies lately committed in various parts of the country had owed their success to the participation of an expert in safes and locks, who had been able, through his position of trust, to reveal to the robbers many secrets of weak bank locks, safes, and vaults. Up to this time these rumors had remained indefinite, and no one ventured to name the man. It was known, however, that the false expert was a man of high standing in his calling and generally regarded as above suspicion. It was also known that there was great jealousy in other gangs of bank robbers because of the amazing success of the gang with whom this man was working, and that overtures even had been made by the leaders of some other gangs to win over to their own gangs this desirable accomplice. Robert Pinkerton had already concluded that the gang so ably assisted was the Dunlap gang; and he was now pretty well persuaded, also, that the Northampton robbery had been committed by the Dunlap gang. There was every reason, therefore, for keeping a sharp eye on the safe-expert Evans.
