This prisoner was a journalist, hitherto living in one of the suburbs of London, and acting as correspondent for certain journals in Ireland and in America. Under a search warrant the police had ransacked every corner of his house. They found what purported to be an incriminatory letter written in invisible ink, also a glass tube containing a liquid which, when tested by the Government analyst, was proved to contain crystals. These crystals, if dissolved in water, could be used for the purpose of making impressions on paper, and such impressions would be invisible until copperas or certain other chemicals had been applied. Beyond these discoveries and the evidence of the informers, there was but little to connect Michael White with the alleged conspiracy. The prisoner was a handsome, middle-aged man, whose intellectual face was in striking contrast with those of the two shifty-eyed and cringing informers, on whom from time to time he bent looks of infinite disgust and scorn. The sympathy of not a few was with the accused; but so strenuous was the conduct of the prosecution, and so adverse the judicial summing up, that only one result could be expected from the trial. One member of White’s family was present through the long and agonising trial--the prisoner’s only son, and there was a double bitterness in the young man’s heart as hour by hour he saw the net being weaved about his father, for he, himself, had his own personal reason for hating Westwood, the zealous junior counsel for the Crown. When the fierce eyes of young Marcus White met the barrister’s, the latter shifted his gaze, fumbled with his papers, or made a show of entering into conversation with other counsel. The prisoner’s son watched these poor devices with a contemptuous smile. A complex, burning sense of wrong filled his breast. The private wrong which he believed had been done to himself by Westwood, blended, as it were, with the wrong that he conceived was being done to his father; and this in turn was interwoven with the sense of wholesale wrong inflicted during centuries upon prisoners and captives who had come within the iron grip of English criminal law.
