Malcolm Sage found that Dawkins had completed his work, and the body of Mr. Challoner had been removed.

Seating himself at the table, he took the automatic pistol in his hand and deliberately removed the cartridges. Then placing the muzzle against his right temple he turned his eyes momentarily on Dawkins, who, having anticipated his wishes, had already adjusted the camera. He removed the cap, replaced it, and then quickly reversed the plate.

Pulling the trigger, Malcolm Sage allowed his head to fall forward, his right hand, which held the pistol, dropping on the table before him. Dawkins took another photograph.

"Now," said Malcolm Sage to Sir James. "You shoot me through the right temple, approaching from behind. Grip my head as if you expected me to resist."

Sir James did as he was requested, Dawkins making another exposure.

Malcolm Sage motioned Thompson to draw the curtains. Then dropping on to his knees by the library door, he took the small mirror he had borrowed from Miss Norman and, placing it partly beneath the door, carefully examined the reflection by the aid of an electric torch.

When he rose it was with the air of a man who had satisfied himself upon some important point. He then turned to Sir James.

"You might get those finger-prints," he said casually. "Get everyone together in the dining-room. See that no one leaves it for at least a quarter of an hour. Thompson will go with you."

"Then you think it was murder?" questioned Sir James.

"I would sooner say nothing just at the moment," was the reply.

Whilst Sir James Walton and Thompson were occupied with a room-full of domestics, talking in whispers as if in the presence of death, Malcolm Sage was engaged in a careful examination of the bottoms of all the doors in the house by means of a mirror placed upwards beneath each. He also removed the keys and gave a swift look at the wards of each.

He moved quickly; yet without haste, as if his brain had entire control of the situation.

One door in particular appeared to interest him, so much so that he entered the room and proceeded to examine it with great thoroughness, taking the utmost care to replace everything as he found it.

From the middle-drawer of the chest-of-drawers, he extracted from under a pile of clothes a thin steel object, some five or six inches in length, wound round with a fine, strong twine. This he slipped into his pocket and, going down into the hall, rang up the manager of the Lewes branch of the Southern Counties and Brown's Bank.

Passing into the library, he searched the drawers of the table at which Mr. Challoner had been found. In one of them he discovered the pass-book. Seating himself at the table, he proceeded to examine it carefully. Turning to the pockets at either end, where cancelled cheques are usually placed, he found both were empty.

When a few minutes later Sir James and Thompson entered with the finger-prints, Malcolm Sage was seated at the table smoking, his gaze concentrated upon the nail of the fourth finger of his right hand. With him a contemplation of his finger-nails in general indicated thoughtful attention; when, however, he raised the hand and began to subject some particular finger-nail to a thorough and elaborate examination, it generally meant the germination of some constructive thesis.

Taking the sheets of paper from Thompson, he went through them rapidly, then drawing a sheet of note-paper from the rack before him he scribbled a hasty note, enclosed it with one of the fingerprints in an envelope, which he sealed, addressed, and handed to Thompson with instructions to see that it was delivered without delay. He also told him to send Peters and Dane to the library.

Three minutes later Tims swung down the drive, his face beaming. He was to drive to Scotland Yard and "never mind the poultry on the road," as Thompson had phrased it.

"Have you the key of the safe, Mr. Dane?" enquired Malcolm Sage as the young man entered, followed by Peters. Dane shook his head and looked at Peters.

"Mr. Challoner always wore it on his key-chain, sir," said the butler.

"Have you any objection to the safe being opened?" enquired Malcolm
Sage to Dane.

"None whatever."

"Then perhaps you will open it?" said Malcolm Sage, turning to Sir
James.

In the safe were found several bundles of letters and share-certificates, and an old cash-box containing some loose stamps; but nothing else.

Malcolm Sage dismissed Peters and Dane, saying that he would be returning to town after dinner. In the meantime he and Sir James strolled about the grounds, discussing the remarkable rise in the chess-world of Capablanca, whilst Dawkins was busily occupied in a darkened bath-room.

Dinner proved a far less sombre meal than luncheon. Malcolm Sage and Sir James between them succeeded in placing young Dane more at his ease. The haunted, shell-shock look left his eyes, and the twitching disappeared from the corners of his mouth.

It was nearly nine o'clock when the distant moan of a hooter announced to Malcolm Sage's alert ears the return of Tims. He rose from the table and walked slowly to the door, where for some seconds he stood with his hand upon the knob.

As the car drew up he slipped into the hall, just as Peters opened the door.

A moment later the butler started back, his right hand seemed to fly to his left breast pocket. At the same moment Malcolm Sage sprang forward. There was a flash, a report, and two bodies fell at the feet of Inspector Wensdale, of Scotland Yard, and another man standing beside him.

In a second, however, they had thrown themselves upon the struggling heap, and when Malcolm Sage rose to his feet it was to look down upon Peters pinned to the floor by the inspector, with the strange man sitting on his legs.
