"Of course we shall," I answered. "It's not likely that they can do more than twenty, and Bobby can knock nearly forty out of this old jigger." I squeezed her hand comfortingly in the darkness.

"I'm going up forward now to keep a look-out for them," I continued. "As soon as you hear me let off a yell you'll know that they're in sight."

With surprising tact Campbell turned away his head, and, having taken full advantage of the opportunity, I swung myself up on to the deck and started off in the direction of the bows.

We were now racing through the water at a tremendous speed, the whole frail shell quivering and rocking beneath the powerful beat of the engine. On either side a great rolling wave curved away from the ship's stern, and behind us a broad wake of white foam gleamed and tossed in the fitful light of the moon.

I crept forward to the end of the deck, and, crouching down in the angle of the railing, stared long and steadily through my glasses.

As there was no sign of our quarry it was clear that she was already round the point. Manning had doubtless seen Bobby's launch returning up the estuary and had wasted no time in getting away from "The Laurels" directly he had discovered Christine's flight. At the lowest computation he must now be at least six miles ahead of us. Provided the moonlight held, however, he would still be in sight by the time he reached the bar, and I glanced anxiously at heavy masses of cloud which were gathering ominously from the south-east.

On we went, the water becoming rougher every minute as we forced our way into the trough of the incoming tide.

Bit by bit the coast opened out on our right, until at last we were almost opposite the big clump of trees which marks the extreme end of the southern shore.

Clutching the rail to steady myself, I once more raised my glasses. Then, in a lather of spray and foam, we suddenly shot out into full view of the sea, and at the same moment a wild, involuntary shout broke from my lips.

There, not half a mile ahead of us, was the launch. She was lying broadside on under the full light of the moon, and one glance was sufficient to show me she had broken down. Even at that distance I could make out two figures working frantically at the engines and another huddled shape in the bows.
