"Oh, well, that"s different," Grace returned.
"What are you going to do with the diamonds?" asked Betty of her father, when they were gathered around the sitting room table, after supper.
"I haven"t fully decided," he said. "I want to make some inquiries in Boston, first, as to whether or not there has been a robbery."
"That"s what I"ll do, too," said Will.
"When are you going to Boston?" asked his sister. "First I heard about that."
"I"m going up in the morning," her brother answered. "I received word to report at the office. There"s something that needs my attention. Ahem!
Uncle Sam can"t get along without me, it seems."
"Nothing like patting yourself on the back," Grace said.
"Just for that you sha"n"t have any of--these!" and Will drew from his pocket a box that unmistakably held candy.
"Oh, Will. I didn"t mean it!" Grace cried. "Of course you"re of value to the government. What are they--those new bitter-sweets?"
"That"s for you to ask, and Amy to know," said Will, as he pa.s.sed Amy the confections.
"Oh, thank you!" she said, blushing furiously.
"Amy Blackford. What I know about you!" mocked Mollie.
"Oh, I"m going to share them, of course."
"Oh, of course!" chanted Grace. "How nice."
"Well, it will keep her still for a while, at least," sighed Will.
"Whom do you mean?" demanded Mollie, catching him by the ear.
"Ouch! Let go! I meant my sister--of course. A fellow wouldn"t dare talk that way about anyone but his sister," confessed Will.
Merrily they discussed the finding of the diamonds, and what disposition might be made of them. The strange actions of the men in the boat, too, came in for a share of attention. The girls were quite sure the men had hidden the box in the sand, though whether or not they knew of the valuable contents was a question.
"Well, they"ll look in vain for it now," declared Betty. "We have it,"
and she glanced at the now empty receptacle.
"Better put it away," suggested her father. "If the servants see it they may ask awkward questions."
"I"ll keep it in my room," said Betty.
"And I"ll have another go at this cipher to-morrow," Allen said. "I have a new idea for solving it."
"I thought you were going to take us girls out in the boat to-morrow,"
objected Mollie.
"So I am. But I can be working on this between times."
"Sorry I can"t be with you," Will said.
"Then you are really going to run up to Boston?" asked Mr. Nelson.
"Yes, sir, I have to go, if I want to keep this new position."
"Well, I"d advise you to do so, then. Go up with me on the express in the morning."
"Thank you, I will."
"And if you hear anything about the diamonds, don"t wait to come back and tell us, write--no, telegraph!" urged Betty.
"It wouldn"t be wise to wire," her father objected. "There is no great rush. I will make some inquiries myself."
"And where will you leave the diamonds, meanwhile?"
"Down here, of course. I"m not going to carry them around with me--too valuable," and Mr. Nelson patted his pocket.
"I"ll take the box to my room, and lock it in my trunk," Betty said.
The evening wore on. It was one of beautiful moonlight, and the party of young people went out on the beach to have a marshmallow roast over a drift-wood fire.
"The sea sparkles--just like diamonds," said Mollie, as they turned to go back to the cottage, when the little frolic had ended.
"Hush!" cautioned Betty. "Some one might hear you," and she looked out over the bay as though she might catch a glimpse of the rough men in the boat.
"You have diamonds on the brain," chided Grace.
The cottage became quiet. Only dim night lights burned. Betty had taken to her room the queer box, which had given up part of its secret. Her father had the diamonds with him.
It was Grace who gave the alarm. Awakening at she knew not what hour, and feeling the need of a drink of water, she donned a dressing gown and found her slippers. As she went through the hall to the bathroom, she saw a dark figure, unmistakably that of a man, gliding down the corridor. Under his arm was the black box, and in one hand was held a tissue paper packet.
"The diamonds!" screamed Grace, her voice shrilling out in the night.
"Burglars are after the diamonds!"
CHAPTER XVI
ON THE BEACH
The whole house was roused in an instant. Lights gleamed in various rooms, and from the quarter where the maids slept came shrill screams that matched those of Grace herself. Hoa.r.s.e shouts came from the rooms of the boys.
But the affair had a most unexpected ending. For the man at whose back Grace was gazing horror-stricken, turned at her sudden shout, and his face betrayed almost as much astonishment, not to say fear, as the countenance of the girl showed.
And then Grace noticed that the man was attired in a bath robe, the pattern of which was strangely familiar to her. She noticed this even before she looked at his face recognizingly, and beheld her host, Mr.
