The constable set off at a run, lumbering heavily over the grass. “And tell the inspector what’s toward,” shouted the sergeant after him. It was this shout that the inspector heard, and that made him throw up the study window and receive at once the constable’s message.

By the time Inspector Blaikie reached the garden, the constable had returned with a glass of water, and Joan had recovered consciousness. She was sitting on the grass, her back propped against the pedestal of the statue, and the sergeant was trying to persuade her to go indoors. The inspector, after a hasty glance at the scene, added his entreaties; but Joan refused to go.

“No, I must see this through,” she said, as to herself. “I’m all right now,” she added, trying to smile at the police officer. “Let me alone, please.” After a time they left her to herself and pursued their investigation of the crime.

Not only were the fact and manner of death plain enough: the actual weapon with which the blow had been dealt was also clearly indicated. Between the body and the statue lay a heavy stone club, evidently a part of the group of statuary against which Joan was resting. It was the club of Hercules, taken from the hand of the stone figure which stood only a few feet away from the body. On the club were unmistakable recent bloodstains, and clotted in the blood were hairs which seemed to correspond closely with those of the dead man.

The blow had been one of immense violence. The stone club itself was so heavy that only a very strong man could have wielded it with effect; and it had evidently been brought down with great force on the back of George Brooklyn’s head by some one standing almost immediately behind him, but rather to the right hand. So much appeared even from a cursory inspection of the wound. It was also evident that the body did not lie where it had fallen. It had been dragged two or three yards along the ground into the temple entry, presumably in order that it might be well out of the way of casual notice. The dragging of it along the ground had left clear traces. A track had been swept clear of loose stones and rubble by the passage of the body, and two little ridges showed where the stones and dust had piled up on each side.

George Brooklyn was fully dressed in his evening clothes, just as he had appeared at dinner the night before. He had evidently come out into the garden without either hat or overcoat—or at least there was no sign of these on the scene of the crime. His body lay where it had been dragged—presumably by the murderer; and all the evidence seemed to show that death had been practically instantaneous. There was no sign of a struggle: the only visible mark of the event was the trail left where the dragging of the body had swept clear of dirt and pebbles the stone approach to the model temple.

All these observations, made by the sergeant within a minute or two of discovering the body, were confirmed by the inspector when he went over the ground. Footmarks, indeed, were there in plenty; but Joan explained that they had all been walking about the garden before dinner on the previous evening, and that nearly all of them had actually stood for some time just outside the porch of the temple. From the footprints it was most unlikely that any valuable evidence would be derived.

Had the situation been less grim Inspector Blaikie would have been inclined to laugh when he found that the man whose body lay in the garden was the very man for whose arrest he had just issued the order. His fear had been that George Brooklyn would slip away before there was time to effect an arrest. That fear was now most completely removed. If George Brooklyn had killed Prinsep upstairs, certainly fate had lost no time in exacting retribution.

The inspector’s immediate business, however, was to see what clues to this second and more mysterious murder might have been left. And it soon appeared to him that valuable evidence was forthcoming. First, on the stone club, his skilled examination plainly revealed a fine set of finger-prints, blurred in places, but still quite decipherable. Moreover, these prints occupied exactly the spaces most natural if the weapon had been used for a murderous assault. The inspector carefully wrapped up the club for forwarding at once to the Finger-Print Department at Scotland Yard.

But good fortune did not end there. Close to the statue of Hercules from which the club had been taken he found, trodden into the ground, a broken cigar-holder. It was a fine amber holder, broken cleanly across the middle. Where the cigar was to be inserted was a stout gold band, and on this band was an inscription, “V.B. from H.L.” Blaikie looked in vain for a cigar end. Probably the holder had dropped from a pocket and been trodden upon. Perhaps from the pocket of the murderer himself.
