Mr. Beardsley, the deputy sheriff, conducted Donald to the elegant mansion of Captain Patterdale. Perhaps no one who saw them walking together suspected that the boat-builder was charged with so gross a crime as stealing the tin box and its valuable contents. Some persons do not like to walk through the streets with sheriffs and policemen; but Donald was not of that sort, for in spite of all the evidence brought against him, he obstinately refused to believe that he was guilty. Even the fact that several notes and other papers had been found in the shop did not impair his belief in his own innocence. Captain Patterdale was in his library nervously awaiting the return of the officer, when they arrived.

"Don John, I hope you will come out of this all right," said he, as they entered.[284]

"I have no doubt I shall, sir," replied Donald. "If I don't, it will be because I can't prove what is the truth."

Mr. Beardsley reported the result of the search, and handed the captain the four fifty-dollar bills with the papers.

"I have no doubt all these were in the tin box," said the nabob, sadly. "The bills are like those paid me by Hasbrook, and these notes are certainly mine. I don't ask you to commit yourself, Don John, but—"

"Commit myself!" exclaimed Donald, with a look of contempt, which, in this connection, was sublime. "I mean to speak the truth, whether I am committed or not."

"Perhaps you will be able to clear this thing up," added Captain Patterdale. "I wish to ask you a few questions."

"I will answer them truly. The only wrong I have done was to conceal what I thought there was no harm in concealing."

"It is not wise to do things in the dark."

"You will excuse me, sir, but you have done the same thing. If I had known that your tin box[285] was stolen, I should have understood several things which are plain to me now."

"What, for instance?"

"If I had known it, I should have brought these bills to you as soon as Laud paid them to me, to see if they belonged to you. And I should have known why Laud was digging clams on Turtle Head."

"Laud says he paid you no money."

"He paid me three hundred and fifty dollars for the Juno—these four bills and the three I paid Mr. Leach."

"He persists that he don't own the Juno, and says that Captain Shivernock lets him have the use of her for taking care of her," continued the nabob.

Donald's face, which had thus far been clouded with anxiety, suddenly lighted up with a cheerful smile, as he produced the cover of an old tuck-diary, which contained the papers of Ramsay & Son. He opened it, and took therefrom the bill of sale of the Juno, in the well-known writing of Captain Shivernock.

"Does that prove anything?" he asked, as he tossed the paper on the desk, within reach of the inquisitor.[286]

"It proves that Captain Shivernock sold the Juno to you, and consequently he has not owned her since the date of this bill," replied the nabob, as he read the paper.

"Is it likely, then, that Captain Shivernock lets Laud have the use of her for taking care of her?" demanded Donald, warmly.

"Certainly not."

"Is it any more likely that, if I own the Juno, I should let Laud use her for nothing, for he says he never paid me a dollar?"

"I don't think it is."

"Then you can believe as much as you please of the rest of Laud's story, which Mr. Beardsley related to me as we walked up," added Donald.

"He says he saw you have the tin box, Don John."

"And I saw him digging clams in the loam on Turtle Head."

"What do you mean by that?"

"I think he buried the tin box there. I saw where he had been digging, but I didn't know any tin box had been stolen then, and thought nothing of it," answered Donald.

At this moment there was a tremendous ring at[287] the door bell, a ring that evidently "meant business." Captain Patterdale opened the door himself, and Captain Shivernock stalked into the room as haughtily as though he owned the elegant mansion. He had been to Newport and Cape May to keep cool, and had arrived a couple of hours before from Portland. Mrs. Sykes had told him all the news she could in this time, and among other things informed him that Captain Patterdale and the deputy sheriff had called to inquire whether Laud had the use of the boat for taking care of her. By this he knew that the tin trunk matter was under investigation. He was interested, and possibly he was alarmed; at any rate, he went to his safe, put the roll of fifty-dollar bills in his pocket, and hastened over to Captain Patterdale's house.

"When people come to my house, and I'm not at home, I don't like to have them talk to my servants about my affairs," blustered the strange man.

"I don't think we meddled with your affairs any further than to ask if Laud Cavendish had the use of the Juno for taking care of her," explained Captain Patterdale.[288]

"It don't concern you. Laud Cavendish does have the use of the Juno for taking care of her."

"Indeed!" exclaimed the good nabob, glancing at Donald.

"Indeed!" sneered the wicked nabob. "You needn't indeed anything I say. I can speak the truth better than you psalm-singers."

"I am very glad you can, Captain Shivernock, for that is what we are in need of just now," laughed the good nabob. "And since we have meddled with your affairs in your absence, it is no more than right that we should explain the reason for doing so. A tin box, containing nearly fourteen hundred dollars in bills, and many valuable papers, was stolen from this room. Three persons, Jacob Hasbrook, Laud Cavendish, and Don John here, passed through the library when they left the house."

"Hasbrook stole it; he is the biggest scoundrel of the three," added the wicked nabob.

"Perhaps not," continued the good nabob. "A bill which I can identify came back to me the other day. Don John paid it to Mr. Leach, and he to me. Don John says Laud Cavendish paid him the bill."[289]

"And so he did," protested Donald, as the captain glanced at him.

"And I gave it to Laud Cavendish," added Captain Shivernock; thus carrying out the programme which had been agreed upon the night before he went on his journey.

Possibly, if Mr. Laud Cavendish had known that the wicked nabob had returned, he would have hastened to see him, and inform him of the change he had made in the programme. If he had done so, their stories might have agreed better. Captain Patterdale, Mr. Beardsley, and Donald were astonished at this admission.

"For what did you pay it to him?" asked the good nabob.

"None of your business what I paid it to him for. That's my affair," bluffed the wicked nabob.

"But this bill was in the box."

"But how do you know it was? I suppose you will say next that I stole the box."

"I hope you will assist me in tracing out this matter," said the good nabob, as he produced the mended bill. "This is the one; I call it the white cross of Denmark."[290]

Captain Shivernock picked up the bill, and took from his pocket his own roll of fifties.

"You must admit that the bill is peculiar enough to be easily identified," added Captain Patter dale.

"I don't admit it," said the strange man, as he threw the four mended bills together on the desk.

"Now, which is it?"

The wicked nabob laughed and roared in his delight when he saw the confusion of the good nabob.

"They are very like," said the good.

"But three of them are mine, and haven't been out of my hands since the 'white cross of Denmark' was put upon them," added the wicked, still shaking his sides with mirth.

"Still I can identify the one that was in the box. That is it;" and Captain Patterdale held up the right one. "This has been folded, while yours have simply been rolled, and have not a crease in them. Hasbrook paid me the money that was stolen."

"The villain swindled it out of me," growled the wicked.[291]

"But he folded his money, however he got it," continued the good.

"I can bring you a dozen bills with the white cross on them," blustered the wicked, "and all of them folded like that one."

"Can you tell where you got it, captain?"

"From the bank," replied he, promptly; and then more to have his hit at the missionaries than to explain the white cross, he told how the bills were torn. "That's all I have to say," he added; and he stalked out of the house, in spite of the host's request for him to remain, without giving a word or even a look to Donald.

"I am astonished," said Captain Patterdale. "Can it be possible that he paid that bill to Laud?"

Perhaps this was the joke of the strange man—simply to confuse and confound a "psalm-singer."

"It looks as though we had lost the clew," said the deputy sheriff. "At any rate, Don John's story is confirmed."

"Why should the captain give Laud so much money?" mused the nabob.

"I know," said Donald. "I told you, in the first place, that I knew where Laud got the money[292] to pay for the Juno; but it was a great secret affecting another person, and he wished me not to tell."

"I remember that, Don John," added the captain.

"He told me that Captain Shivernock gave him the money; but he would not tell me why he gave it to him; but I knew without any telling, for the captain gave me sixty dollars, besides the Juno, for holding my tongue."

"About what?" asked the nabob, deeply interested in the narrative.

"I don't understand the matter myself; but............
