Again, almost savagely, he strove to thrust away the thoughts that troubled him.  The child was bound to be contaminated sooner or later; but what was that to him?  It was out of his power to deliver her.  He was no rescuer of damsels in distress.

So he put away from him the thought of Rosa Mundi and the thought of the child called Rosemary who had come to him out of the morning sunlight, and went back to his hotel doggedly determined that neither the one nor the other should disturb his peace of mind.  He would take refuge in his work, and forget them.

But late that night he awoke from troubled sleep to hear Ellis Grant laugh again in careless triumph—­the laugh of the man who knows that he has drawn a prize.

It was not a restful night for Randal Courteney, and in the early morning he was out again, striding over the sunlit sands towards his own particular bathing-cove beyond the breakwater.

The tide was coming in, and the dashing water filled all the world with its music.  A brisk wind was blowing, and the waves were high.

It was the sort of sea that Courteney revelled in, and he trusted that, at that early hour, he would be free from all intrusion.  So accustomed to privacy was he that he had come to regard the place almost as his own.

But as he topped the breakwater he came upon a sight that made him draw back in disgust.  A white mackintosh lay under a handful of stones upon the shingly beach.  He surveyed it suspiciously, with the air of a man who fears that he is about to walk into a trap.

Then, his eyes travelling seaward, he spied a red cap bobbing up and down in the spray of the dancing waves.

The impulse to turn and retrace his steps came to him, but some unknown force restrained him.  He remembered suddenly the current that had more than once drawn him out of his course when bathing in those waters, and the owner of the red cap was alone.  He stood, uncertain, on the top of the breakwater, and watched.

Two minutes later the very event he had pictured was taking place under his eyes, and he was racing over the soft sand below the shingle at the top of his speed.  Two arms were beating wildly out in the shining sparkle of water, as though they strove against the invisible bars of a cage, and a voice—­the high, frightened voice of a child—­was calling for help.

He flung off his coat as he ran, and dashed without an instant’s pause straight into the green foaming waves.  The water swirled around him as he struck out; he clove his way through it, all his energies concentrated upon the bobbing red cap and struggling arms ahead of him.  Lifted on the crest of a rushing wave, he saw her, helpless as an infant in the turmoil.  Her terrified eyes were turned his way, wildly beseeching him.  He fought with the water to reach her.

He realized as he drew nearer that she was not wholly inexperienced.  She was working against the current to keep herself up, but no longer striving to escape it.  He saw with relief that she had not lost her head.
