It seems that a man named Amoux has changed his mind and now accuses George Britton, "a notorious swindler & suborner of perjury," of inducing "him by offers of money to give his last testimony in the Lewis Will case." Folds. Slight separation along the folds at the right edge. At the time of the writing of this letter, Pinkerton, the brother of Pinkerton Detective Agency founder, Allan Pinkerton, was superintendent of the agency.
