<h2>Chapter XXI</h2>
<p>It seemed to Lydia that she had been abroad for years, though in reality
she had been three days in Cap Martin, when Mr. Marcus Stepney became a
regular caller.</p>
<p>Even the most objectionable people improve on acquaintance, and give the
lie to first impressions.</p>
<p>Mr. Stepney never bored her. He had an inexhaustible store of anecdotes
and reminiscences, none of which was in the slightest degree offensive.
He was something of a sportsman, too, and he called by arrangement the
next morning, after his introduction to the Cap Martin household, and
conducting her to a sheltered cove, containing two bathing huts, he
introduced her to the exhilarating Mediterranean.</p>
<p>Sea bathing is not permitted in Monte Carlo until May, and the water was
much colder than Lydia had expected. They swam out to a floating
platform when Mr. Briggerland and Jean put in an appearance. Jean had
come straight from the house in her bathing-gown, over which she wore a
light wrap. Lydia<span class="pagenum"><SPAN name="Page_163" id="Page_163"></SPAN></span> watched her with amazement, for the girl was an
expert swimmer. She could dive from almost any height and could remain
under water an alarming time.</p>
<p>"I never thought you had so much energy and strength in your little
body," said Lydia, as Jean, with a shriek of enjoyment, drew herself on
the raft and wiped the water from her eyes.</p>
<p>"There's a man up there looking at us through glasses," said Briggerland
suddenly. "I saw the flash of the sun on them."</p>
<p>He pointed to the rising ground beyond the seashore, but they could see
nothing.</p>
<p>Presently there was a glitter of light amongst the green, and Lydia
pointed.</p>
<p>"I thought that sort of thing was never done except in comic
newspapers," she said, but Jean did not smile. Her eyes were focused on
the point where the unseen observer lay or sat, and she shaded her eyes.</p>
<p>"Some visitor from Monte Carlo, I expect. People at Cap Martin are much
too respectable to do anything so vulgar."</p>
<p>Mr. Briggerland, at a glance from his daughter, slipped into the water,
and with strong heavy strokes, made his way to the shore.</p>
<p>"Father is going to investigate," said Jean, "and the water really is
the warmest place," and with that she fell sideways into the blue sea
like a seal, dived down into its depths, and<span class="pagenum"><SPAN name="Page_164" id="Page_164"></SPAN></span> presently Lydia saw her
walking along the white floor of the ocean, her little hands keeping up
an almost imperceptible motion. Presently she shot up again, shook her
head and looked round, only to dive again.</p>
<p>In the meantime, though Lydia, who was fascinated by the manœuvre of
the girl, did not notice the fact, Mr. Briggerland had reached the
shore, pulled on a pair of rubber shoes, and with his mackintosh
buttoned over his bathing dress, had begun to climb through the
underbrush towards the spot where the glasses had glistened. When Lydia
looked up he had disappeared.</p>
<p>"Where is your father?" she asked the girl.</p>
<p>"He went into the bushes." Mr. Stepney volunteered the information. "I
suppose he's looking for the Paul Pry."</p>
<p>Mr. Stepney had been unusually glum and silent, for he was piqued by the
tactless appearance of the Briggerlands.</p>
<p>"Come into the water, Marcus," said Jean peremptorily, as she put her
foot against the edge of the raft, and pushed herself backward, "I want
to see Mrs. Meredith dive."</p>
<p>"Me?" said Lydia in surprise. "Good heavens, no! After watching you I
don't intend making an exhibition of myself."</p>
<p>"I want to show you the proper way to dive," said Jean. "Stand up on the
edge of the raft."<span class="pagenum"><SPAN name="Page_165" id="Page_165"></SPAN></span></p>
<p>Lydia obeyed.</p>
<p>"Straight up," said Jean. "Now put both your arms out wide. Now——"</p>
<p>There was a sharp crack from the shore; something whistled past Lydia's
head, struck an upright post, splintering the edge, and with a whine
went ricochetting into the sea.</p>
<p>Lydia's face went white.</p>
<p>"What—what was that?" she gasped. She had hardly spoken before there
was another shot. This time the bullet must have gone very high, and
immediately afterwards came a yell of pain from the shore.</p>
<p>Jean did not wait. She struck out for the beach, swimming furiously. It
was not the shot, but the cry which had alarmed her, and without waiting
to put on coat or sandals, she ran up the little road where her father
had gone, following the path through the undergrowth. Presently she came
to a grassy plot, in the centre of which two tall pines grew side by
side, and lying against one of the trees was the huddled figure of
Briggerland. She turned him over. He was breathing heavily and was
unconscious. An ugly wound gaped at the back of his head, and his
mackintosh and bathing dress were smothered with blood.</p>
<p>She looked round quickly for his assailant, but there was nobody in
sight, and nothing to indicate the presence of a third person but two
shining brass cartridges which lay on the grass.<span class="pagenum"><SPAN name="Page_166" id="Page_166"></SPAN></span></p>
