“Don’t want to squeal on him, eh? Oh, that’s all right. I’m glad to see that there is still some honor among thieves. We’ll get him, all right. He knows nothing of what’s happened here, and when he returns he’ll find a little surprise waiting for him.”

Still the men said nothing.

“That’s all right, boys, just hold your tongues.” The lieutenant turned to Chot. “I’ll leave my two men to take charge of these fellows. We’re going to stay at the lodge until Lawrence returns.”

“That suits us,” said Chot. “We’ll all wait, and if we boys can render any further assistance, just command us.”

The two men from the revenue boat were placed as guards over the prisoners, thus relieving the boys of all responsibility in this regard.

Lieutenant Winters took up his abode at the lodge, sending the motor-boat around to the east end of the island, where, in a little cove, she was concealed from view from the north island, as well as the approaches from the west and south, by one of which routes Mr. Lawrence would be sure to come on his return to the island.

“Lawrence will no doubt come as he went, in the night,” said Lieutenant Winters, “so we had best arrange a watch.”

“He will probably enter by means of the secret passage,” said Tom. “That is the way he left, I am sure.”

“In other words,” said the lieutenant, “believing that you know nothing of the underground exit, he will probably seek to enter his room in the night and appear before you at the breakfast table as a complete surprise.”

“That’s the way he likes to do things, I should say, from what little opportunity I have had for observation,” Tom replied.
