“I am off to see the Chief Constable, Knox. Aylesbury must be superseded at whatever cost. If the Chief Constable fails I shall not hesitate to go higher. I will get along to the garage. I don’t expect to be more than an hour. Meanwhile, do your best to act as a buffer between Aylesbury and the women. You understand me?” “Quite,” I returned, shortly. “But the task may prove no light one, Harley.” “It won’t,” he assured me, smiling grimly. “How you must regret, Knox, that we didn’t go fishing!” With that he was off, eager-eyed and alert, the mood of dreamy abstraction dropped like a cloak discarded. He fully realized, as I did, that his unique reputation was at stake. I wondered, as I had wondered at the Guest House, whether, in undertaking to clear Colin Camber, he had acted upon sheer conviction, or, embittered by the death of his client, had taken a gambler’s chance. It was unlike him to do so. But now beyond reach of that charm of manner which Colin Camber possessed, and discounting the pathetic sweetness of his girl-wife, I realized how black was the evidence against him. Occupied with these, and even more troubled thoughts, I was making my way toward the library, undetermined how to act, when I saw Val Beverley coming along the corridor which communicated with Madame de Stämer’s room. I read a welcome in her eyes which made my heart beat the faster. “Oh, Mr. Knox,” she cried, “I am so glad you have returned. Tell me all that has happened, for I feel in some way that I am responsible for it.” I nodded gravely. “You know, then, where Inspector Aylesbury went when he left here, after his interview with you?” She looked at me pathetically. “He went to the Guest House, of course.” “Yes,” I said; “he was close behind us.” “And”--she hesitated--“Mr. Camber?” “He has been detained.” “Oh!” she moaned. “I could hate myself! Yet what could I say, what could I do?” “Just tell me all about it,” I urged. “What were the Inspector’s questions?” “Well,” explained the girl, “he had evidently learned from someone, presumably one of the servants, that there was enmity between Mr. Camber and Colonel Menendez. He asked me if I knew of this, and of course I had to admit that I did. But when I told him that I had no idea of its cause, he did not seem to believe me.” “No,” I murmured. “Any evidence which fails to dove-tail with his preconceived theories he puts down as a lie.” “He seemed to have made up his mind for some reason,” she continued, “that I was intimately acquainted with Mr. Camber. Whereas, of course, I have never spoken to him in my life, although whenever he has passed me in the road he has always saluted me with quite delightful courtesy. Oh, Mr. Knox, it is horrible to think of this great misfortune coming to those poor people.” She looked at me pleadingly. “How did his wife take it?” “Poor little girl,” I replied, “it was an awful blow.”
