As the car drew up, the hall-door of "The Cedars" was thrown open by the butler, a fair-haired clean-shaven man of about forty-five, with grave, impa.s.sive face, and eyes that gave the impression of allowing little to escape them.

As he descended the flight of stone-steps to open the door of the car, a young man appeared behind him. A moment later Sir James was introducing him to Malcolm Sage as "Mr. Richard Dane."

Dark, with smoothly-brushed hair and a toothbrush moustache, he might easily have been pa.s.sed over in a crowd without a second glance. He was obviously and acutely nervous. His fingers moved jerkily, and there were twitchings at the corners of his mouth that he seemed unable to control. It was not a good-tempered mouth. He appeared unconscious of the presence of Malcolm Sage. His eyes were fixed upon the second car, which had just drawn up, and from which Thompson and Dawkins were removing the photographic paraphernalia.

Peters conducted Sir James and Malcolm Sage to the dining-room, where luncheon was laid.

"Shall I serve luncheon, Sir James?" he enquired, ignoring Dane, who was clearly unequal to the strain of the duties of host.

Sir James looked across at Malcolm Sage, who shook his head.

"I'll see the library first," he said. "Sir James will show me.

Fetch Dawkins," he said to Thompson, and he followed Sir James through the house out on to the lawn.

As they entered the library by the French-windows, a tall, sandy man rose from the armchair in which he was seated. He was Inspector Gorton of the Suss.e.x County Constabulary. Malcolm Sage nodded a little absently. His eyes were keenly taking in every detail of the figure sprawling across the writing-table. The head rested on the left cheek, and there was an ugly wound in the right temple from which blood had dripped and congealed upon the table. In the right hand was clutched a small, automatic pistol. The arm was slightly curved, the weapon pointing to the left.

Having concluded his examination of the wound, Malcolm Sage drew a silk-handkerchief from his pocket, shook out its folds and spread it carefully over the blood-stained head of Mr. Challoner.

Sir James looked across at him, appreciation in his eyes. It was one of those little human touches, of which he had discovered so many in Malcolm Sage, and the heads of government departments in Whitehall so few.

Malcolm Sage next proceeded to regard the body from every angle, even going down on his knees to see the position of the legs beneath the table. He then walked round the room and examined everything with minute attention, particularly the key of the door, which Sir James had replaced in its position on the inside. The keyhole on both sides of the door came in for careful scrutiny.

He tried the door of a small safe at the far-end of the room; it was locked. He then examined the fastenings of the French-windows.

Finally he returned to the table, where, dropping on one knee on the left-hand side of the body, he drew a penknife from his pocket, and proceeded with great care and deliberation to slit up the outer seam of the trousers so that the pocket lay exposed.

This in turn he cut open, taking care not to disturb the bunch of keys, which, attached to a chain, lay on the thigh, a little to the left.

The others watched him with wide-eyed interest, the inspector breathing heavily.

Having a.s.sured 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 princ.i.p.al 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 att.i.tude towards the official police was generally determined by their att.i.tude 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 att.i.tude 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 p.r.o.nounced the wound self-inflicted, and even if he had not done so, the circ.u.mstantial 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.

Mrs. Trennett, the housekeeper, was incoherent in her voluble anxiety to give information. The maids were almost too frightened to speak, and from none was anything tangible extracted.

No one had any reason for being near the library late at night.

When Peters' turn came, he told his story with a clearness and economy of words that caused Malcolm Sage mentally to register him as a good witness. He was a superior kind of man, who had been in his present position only some six months; but during that time he had given every satisfaction, so much so that Mr. Challoner had remarked to Sir James that he believed he had found a treasure.

According to Peters' account, at a quarter-past eleven on the previous evening he had gone to the library, as was his custom, to see if there were anything else that Mr. Challoner required before he locked up for the night. On being told there was nothing, he had accordingly seen to the fastenings of doors and windows and gone to bed.

"What was Mr. Challoner doing when you entered the room?" enquired Malcolm Sage, intent upon a design he was drawing upon the surface of the salt.

"He was sitting at the table where I found him this morning."

"What was he actually doing?"

"I think he was checking his bankbook, sir."

"Did you notice anything strange about his manner?"

"No, sir."

"When you found that his bed had not been slept in were you surprised?"

"Not greatly, sir," was the response. "Once before a similar thing happened, and I heard from the other servants that on several occasions Mr. Challoner had spent the night in the library, having fallen asleep there."

"When you told Mr. Dane that his uncle had not slept in his room, and that the library door was locked on the inside, what did he say?"

"He said, 'Good Lord! Peters, something must have happened.'"

"Mr. Dane knew that on previous occasions his uncle had spent the night in his study?" enquired Malcolm Sage, smoothing out the design upon which he had been engaged and beginning another.

"I think so, sir," was the response.

"The pistol was the one he used at target-practice?"

"Yes, sir."

"Where did he keep it?"

"In the third right-hand drawer of his table, sir."
