Having assured himself that the keys would not slide off, Malcolm Sage rose and turned to Dawkins: "I want a plate from the right, the left, the front, and from behind and above. Also an exposure showing the position of the legs, and another of the keys." Dawkins inclined his head. He was a grey, bald-headed little man who had only one thought in life, his profession. He seldom spoke, and when he did his lips seemed scarcely to part, the words slipping out as best they could. Happy in the knowledge that his beloved camera was once more to be one of the principal witnesses in the detection of a crime, Dawkins set himself to his task. "When Dawkins has finished," said Malcolm Sage, turning to the inspector, who had been watching the proceedings with ill-disguised impatience, "you can remove the body; but leave the pistol. Give Mr. Challoner's keys to Sir James. And now I think we might lunch," he said, turning to Sir James. Malcolm Sage's attitude towards the official police was generally determined by their attitude towards him. In the Department Z days, he had been known at Scotland Yard as "Sage & Onions." What the phrase lacked in wit was compensated for by the feeling with which it was frequently uttered. The police officers made no effort to dissemble the contempt they felt for a department in which they saw a direct rebuke to themselves. Later, however, their attitude changed, and Malcolm Sage was brought into close personal touch with many of the best-known officers of the Criminal Investigation Department. He had never been known to speak disparagingly, or patronisingly, of Scotland Yard. On the other hand, he lost no opportunity of emphasising the fact that it was the head-quarters of the most efficient police force in the world. He did not always agree with its methods, which in many ways he regarded as out-of-date. As Malcolm Sage left the room, the inspector shrugged his shoulders. The whole thing was so obvious that, but for the presence of Sir James Walton, he would have refused to delay the removal of the body. The doctor had pronounced the wound self-inflicted, and even if he had not done so, the circumstantial evidence was conclusive. Luncheon was eaten in silence, a constrained and uncomfortable meal. Malcolm Sage ate as he always ate when his mind was occupied, with entire indifference as to what was on the plate, from which his eyes never lifted. Sir James made several ineffectual efforts to draw Dane into conversation; but at each remark the young man started violently, as if suddenly recalled to his surroundings. Finally Sir James desisted, and the meal concluded in abysmal silence. Malcolm Sage then announced that he would examine the various members of the household, and Dane and Peters left the room. One by one the servants entered, were interrogated, and departed. Even the gardener and his wife, who lived at the lodge by the main-gates, were cross-questioned.
