He himself was at the centre of the line and was the first to enter the tiny wood. The advance was slow; for here there was some undergrowth which might offer a hiding-place to the fugitive; and this was carefully scrutinized, clump by clump, before the line moved forward as a whole. Michael meant to make certain of capturing the burglar; and he could afford now to go about the matter deliberately. Fresh reinforcements in twos and threes were still streaming in from the pine-wood.

It took only a few minutes, however, to draw his screen through the spinney; for the belt of trees was a narrow one. Every instant he expected to hear a shout indicating that the quarry had been run to earth; but none came. His line emerged intact from the trees, forming an arc of which the cliff-face was the chord; and as his men came out into the moonlight Michael had to admit to himself that no one could well have crept through any gap in the cordon.

“He must be out here, hiding among these seats,” he shouted. “Don’t break your line any more than you can help. Advance to that balustrade in front. Rush him, if he shows up.”

Now that he was sure of his quarry, Michael at last had leisure to note the tincture of the bizarre in the scene before him. The high-riding moon whitened the terrace and touched with glamour the motley costumes of the hunters preparing for their final swoop. Here Robin Hood and a hatless Flying Dutchman were stooping to peer below one of the marble seats. Farther along the line Lohengrin and a Milkman discussed something eagerly in whispers. On the left the Prehistoric Man loomed up like a Troglodyte emerging from his cave; while beyond him Mephistopheles leaned upon the railing, scanning the water below. From the inky shadow of the spinney Felix the Cat stole softly out to join the cordon.

“A weird-looking gang we are,” Michael commented to himself as he gazed about him.

Only a few steps separated the hunters from the clear floor of the terrace. In a second or two at most, the man they were chasing must break cover and make a dash for liberty or else tamely surrender. Slowly the line crept forward.

“We’ve got him now!” a voice cried, exultantly.

But the living net swept on past the marble tier without catching anything in its meshes. Between it and the balustrade was nothing but the untenanted paving of the terrace.

“He’s got away!” ejaculated some one in tones of complete amazement. “Well, I’m damned if I see how he managed it.”

The chain broke up into individuals, who hurried hither and thither on the esplanade searching even in the most unlikely spots for the missing fugitive. All at once Michael’s eye caught something which had been concealed in the shadows thrown by the moon.
