'He wants to avoid them,' I said to myself, 'and he seems to be looking for someone.' And then I turned my attention to the brunette once more.
At ten o'clock the music had ceased, and the people were scattered upon the Plaza. The electric fountains had ceased to send up multi-coloured spray, and some of the lights in the glittering chains about the Grand Basin were fading out. On the streets and avenues leading away from the Plaza there was still sufficient light, but the Wooded Island, which as yet had not participated in the great illuminations, was not brilliantly lighted. In fact, under the trees, and among the winding shrub-bordered paths, there were many shadowed nooks and gloomy recesses.
And yet it was towards the Wooded Island that the brunette and her companion led me, wondering much, and keeping at a distance to avoid the glances often sent back by the little adventuress.
I had just stepped off the path to avoid the gleam of light that fell across it from the light just at the curve, when a quick step sounded close by, and a tall figure passed me in haste, going the way the two had taken—the form of the handsome guard.
I had followed them past the east front of the Electricity Building, and between it and the canal, and then across the bridge opposite, and midway between the north front of the Electricity and Mines Buildings, across the little island of the Hunters' Camp, and across the second bridge, and it was near this last spot that the guard had passed me.
A few paces beyond me he seemed at a loss, and paused to look about him; and as he did so, the two women, who had made a short-cut across the forbidden grass, came out into the path directly between us, and retraced their steps toward the bridge.
It was past ten o'clock now, and very quiet just here, and the lamps at the ends of the bridge, the only lights just here, seemed to me less brilliant than usual. As the two women came toward me, somewhat slowly, I drew back into the shelter of the bushes, and they passed me, speaking low. I remember that, at the moment, the thought of our singular isolation in this spot crossed my mind, and I wondered why we did not see somewhere a second Columbian Guard on duty.
And now my guard passed me hurriedly, looking neither to right nor left, and I crept forward across the grass and under the trees. I could now see that the women had stopped upon the bridge nearest the island, and on the side facing eastward, and looking over the face of the lagoon at its widest, and across to the silent and now almost utterly darkened Manufactures Building, and that the guard had joined them. Rather, that he was speaking with the brunette, while the other, with bent head, stood a little aloof.
And then, as I looked and wondered, two figures arose suddenly, or so it seemed, from the base of the statue at the end of the bridge, just behind the guard, and as he bent his head toward the little decoy there was a silent, forward spring, a sudden heaving movement, and a splash. With a shout for help I bounded forward, tearing off my coat as I ran. I was conscious of four flying figures that passed me, hastening islandward, but my thoughts were all for that figure that had gone over into the lagoon silently and without a struggle.
As I tore down the bank at the side of the pier, I heard low voices, and could see a boat in the shadow of the bridge; and as I was about to plunge into the water, a voice said sharply:
