de Lyster had sworn to herself to make the
best use of her opportunities, and to secure wealth at least for this
her beloved brother. Allan should marry one of the girls, and then his
fortune in life would be made. After passing them all in review she
decided on Marion Arleigh. Not only was she the wealthiest heiress, but
in her case there were no parents to interfere--no father with stern
refusal, no mother with tearful pleadings. When she was of age she could
please herself--marry Allan, if he would persuade her to do so, and then
he would be master of all her wealth. She began her management of the
somewhat difficult business with tact and diplomacy worthy of a
gray-headed diplomatist. She spoke so incessantly of her
brother--praising his genius, his great gifts--that Marion could not
help thinking of him. She studied the character of this young heiress,
and played so adroitly upon her weakness that Marion Arleigh, in her
sweet girlish simplicity, had no chance against her.

When Allan Lyster came, to all outward appearances no one could have
been more reserved; he rarely addressed his pupils, never except on
matters connected with the lesson. He never looked at them. Miss
Carleton flattered herself that she had found a treasure. Allan was not
only the cheapest master she had ever had, but he was also a model of
discretion. Yet none the less had he adopted his sister's ideas and made
up his mind to woo and win Marion Arleigh.

"It is well worth your while to try," said his sister. "There are no
parents to interfere; she will be her own mistress the very day she is
of age."

"But she is only about seventeen now," said Allan; "there will be so
long to wait."

"The prize is well worth waiting for. Half the peers in England would be
proud and thankful to win it. If you play your cards well, Allan, in one
way or another you must succeed. Let me tell you the most important
thing to do."

"What is that?" he asked, looking admiringly into his sister's face.

"Persuade her to write to you, and mind that her letters to you contain
a promise of marriage. Do you see the importance of that?"

"You are a clever woman, Adelaide; with you to help me I cannot fail."

And he did not fail. Adelaide had arranged her plans too skillfully for
that. She began by saying how much Allan admired Marion; then, seeing
the idea was not displeasing to the young heiress, she gradually told
her how he was certain to die of love for her.
