She swam well. His practised eye saw that. Her strong, easy strokes
carried her swiftly over the swell of the waves. He stared, transfixed.
He was a well-brought-up young man, and he knew how ill-bred it was to
stare; but this was a special occasion. Ordinary rules of conventional
etiquette could not apply to a case like this. He stared. More, he
gaped. As the girl passed on into the shadow of the pier he leaned
farther over the rail, and his neck extended in joints like a
telescope.

At this point the girl turned to swim on her back. Her eyes met his.
Hers were deep and clear; his, bulging. For what seemed an eternity to
George, she continued to look at him. Then, turning over again, she
shot past under the pier.

George's neck was now at its full stretch. No power of will or muscle
could add another yard to it. Realizing this, he leaned farther over
the rail, and farther still. His hat slid from his hand. He grabbed at
it, and, overbalancing, fell with a splash into the water.

Now, in ordinary circumstances, to fall twelve feet into the ocean with
all his clothes on would have incommoded George little. He would hardly
have noticed it. He would have swum to shore with merely a feeling of
amused self-reproach akin to that of the man who absent-mindedly walks
into a lamp-post in the street. When, therefore, he came to the
surface he prepared without agitation to strike out in his usual bold
fashion. At this moment, however, two hands, grasping him beneath the
arms, lifted his head still farther from the waves, and a voice in his
ear said, 'Keep still; don't struggle. There's no danger.'
