One man, however, believed nothing of the sort, and that man was Professor Cox-Raythwaite. His big, burly form had been very much in evidence at all the proceedings before coroner and magistrate. He had followed every scrap of testimony with the most scrupulous care; he had made notes from time to time; he had given up his leisure moments, and stolen some from his proper pursuits, to a deep consideration of the case as presented by the police. And on the afternoon which saw Barthorpe committed to take his trial, he went away from Bow Street, alone, thinking more deeply than ever. He walked home to his house in Endsleigh Gardens, head bent, hands clasped behind his big back, the very incarnation of deep and ponderous musing. He shut himself in his study; he threw himself into his easy chair before his hearth; he remained smoking infinite tobacco, staring into vacancy, until his dinner-bell rang. He roused himself to eat and drink; then he went out into the street, bought all the evening newspapers he could lay hands on, and, hailing a taxi-cab, drove to Portman Square. Peggie, Mr. Tertius, and Selwood had just dined; they were sitting in a quiet little parlour, silent and melancholy. The disgrace of Barthorpe's arrest, of the revelations before coroner and magistrate, of his committal on the capital charge, had reduced Peggie to a state of intense misery; the two men felt hopelessly unable to give her any comfort. To both, the entrance of Cox-Raythwaite came as a positive relief. Cox-Raythwaite, shown into the presence of these three, closed the door in a fashion which showed that he did not wish to be disturbed, came silently across the room, and drew a chair into the midst of the disconsolate group. His glance round commanded attention. "Now, my friends," he said, plunging straight into his subject, "if we don't wish to see Barthorpe hanged, we've just got to stir ourselves! I've come here to begin the stirring." Peggie looked up with a sudden heightening of colour. Mr. Tertius slowly shook his head. "Pitiable!" he murmured. "Pitiable, most pitiable! But the evidence, my dear Cox-Raythwaite, the evidence! I only wish----" "I've been listening to all the evidence that could be brought before coroner's jury and magistrate in police court," broke in the Professor. "Listening with all my ears until I know every scrap of it by heart. And for four solid hours this afternoon I've been analysing it. I'm going to analyse it to you--and then I'll show you why it doesn't satisfy me. Give me your close attention, all of you." He drew a little table to his elbow, laid his bundle of papers upon it, and began to talk, checking off his points on the tips of his big, chemical-stained fingers.
