"The great trouble ought to come first," declared Louise. "It is the foundation upon which rest all the mysterious occurrences following, and once we have learned what the great trouble was, the rest will be plain sailing."

"I agree with you," said Beth; "and perhaps Joseph Wegg will be able to tell us what the trouble was that ruined the lives of his parents, as well as of Old Hucks and his wife, and caused them all to flee here to hide themselves."

It was not until the following morning that the Major found an opportunity to give the confederates a solemn wink to indicate he had news to confide to them. They gathered eagerly on the lawn, and he told them of the finding of Joe Wegg in the isolated cabin, and how old Thomas and Nora, loving the boy as well as if he had been their own child, had sacrificed everything to assist him in his extremity.

"So ye see, my avenging angels, that ye run off the track in the Hucks matter," he added, smiling at their bewildered faces.

Patsy was delighted at this refutation of the slanderous suspicions that Thomas was a miser and his smiling face a mask to hide his innate villainy. The other girls were somewhat depressed by the overthrow of one of their pet theories, and reluctantly admitted that if Hucks had been the robber of his master and old Will Thompson, he would not have striven so eagerly to get enough money to send to Joe Wegg. But they pointed out that the old servant was surely hiding his knowledge of Captain Wegg's past, and could not be induced to clear up that portion of the mystery which he had full knowledge of. So, while he might be personally innocent of the murder or robbery, both Beth and Louise were confident he was attempting to shield the real criminal.

"But who is the real criminal?" inquired Patsy.

"Let us consider," answer Louise, with the calm, businesslike tone she adopted in these matters. "There is the strolling physician, whom we call the Unknown Avenger, for one. A second suspect is the man McNutt, whose nature is so perverted that he would stick at nothing. The third suspicious individual is Mr. Bob West."

"Oh, Louise! Mr. West is so respectable, and so prosperous," exclaimed
Patsy.

"It's a far jump from McNutt to West," added Beth.

"Leaving out Hucks," continued Louise, her eyes sparkling with the delightful excitement of maintaining her theories against odds, "here are three people who might have been concerned in the robbery or murder. Two of them are under our hands; perhaps Joseph Wegg may be able to tell us where to find the third."
