THE AUTO BOYS' MYSTERY

CHAPTER I
PROLOGUE

The Auto Boys had been camped on the unfrequented shore of Opal Lake for several days. At first hunting and fishing were the only enlivening features of this, their unusual summer outing.

Opal Lake, far up in the big northern woods, had at this time no other campers. True, there was an abandoned clubhouse on a nearby point not far from where Phil Way, Billy Worth, Dave MacLester and Paul Jones selected the spot for their Outing Camp. But, until within a day or two, even the clubhouse had seemed to be as it looked, deserted.

But a smoke being seen one day, the boys had become curious. Without actually entering the house itself, they had made individual or collective trips that way. Also strange sounds had been heard, and even human presence had been detected. Finally Paul, the youngest of the boys, made a cautious trip thither and even entered the house where he had heard voices, and otherwise had detected that real folks were undoubtedly there; though why they were there Paul could only guess. Perhaps they were in search of a bag of money, said to be twenty thousand dollars, stolen three years before and supposed still to be hidden somewhere in that region.

Strange men had been seen near the end of a gravel road which the Longknives Club (owners of the now abandoned clubhouse) were then constructing for their own use and convenience. The unexpected loss of this money caused the work to stop, while the workmen, including a Swedish foreman, Nels Anderson by name, remained unpaid to this day.

Aside from the clubhouse, the nearest inhabitants to the boys' camp were this same Anderson and his family, who lived in a small clearing five or six miles away on the trail leading to Staretta, a small town perhaps a dozen miles further on. This was the nearest town to Opal Lake which was, indeed, a veritable "Lake of the Woods."

When Paul Jones, finally escaping through the cellar window, left the clubhouse without being discovered, he ran across in the dark another somebody who vanished, uttering strange and savage oaths. Paul also made himself scarce in another direction and happened upon Chip Slider, whose merry response to Paul's greeting caused both soon to become so friendly that Paul took Chip to their camp, where a warm meal soon loosened the boys' tongues and there was a general interchange of opinions about game, fish, the big woods, and at last the abandoned house on the point.

Here the boys learned from Chip that a man named Murky was also in the woods and supposedly after that lost or stolen satchel, thought by many to be hidden somewhere near. They learned from Chip more of the robbery of Grandall, the treasurer of the Longknives, by this same Murky; also that Murky himself, through the connivance of Grandall, was held up by Chip's father by the order of Grandall. The scheme seemed to have been for Grandall to get the money thus entrusted to his care in a way that would divert suspicion against himself and direct it elsewhere. After sufficient time had elapsed, then Grandall would manage to use that money, meanwhile placating Chip's father, supposedly by bribes.

So open, frank and friendless was young Chip that he won the Auto Boys' confidence, and stayed on at the camp, proving himself a valuable aid and an added link in their narrow social life.

Shortly before this Chip, encountering Murky in the woods, had been badly beaten by the other, and had been seen with a bandaged head by some of the boys. This induced much pity for the homeless lad, while Chip's knowledge of Murky and matters connected with the robbery just alluded to, made him serviceable in the matter of knowing more about what was going on in and about the house on the point. It appeared, too, that others of the boys during previous scoutings about the point had seen Murky, though they did not know who or what he was until Slider enlightened them.

The general conclusion was that the voices heard inside the house were more than apt to have indicated the presence of Murky and Grandall, still on trail of stolen money that must have, in some way, slipped into unknown hands. Still nothing was sure or settled in their minds except that Chip was a good fellow and Murky a bad one from almost any point of view one might take.

Another point occurred to Phil Way, the oldest and the leader of the Auto Boys; not one of suspicion against Chip, but for general enlightenment.

A recent visit to their camp when all the boys were away had occurred. Things had been taken, including provisions, bedding and dishes. Perhaps young Slider, more familiar with the woods life nearby, might have some knowledge that would lead to the perpetrator.

Taken all round, the camp thought itself rather in luck that Paul had met this strange homeless lad in the way and under the circumstances he did.

Nels Anderson, the giant Swede, had also been seen under suspicious circumstances by some of the boys. Taken altogether, the whole matter was attractive enough to foster certain ambitions inside the lads, who were too apt to fancy themselves amateur detectives, a vocation they knew little or nothing about, rather than young woodsmen, hunters, or anglers, pursuits they really did have some knowledge of and also some skill.

CHAPTER II
A QUIET, TRANQUIL SUNDAY

A great bull-frog whose hoarse croaking could always be heard above other sounds about the lake, "beginning at exactly eleven o'clock each night"–at least so Paul Jones positively stated–had started his unmelodious serenade a long time before the Auto Boys and their visitor prepared for bed. Paul's adventure, Chip Slider's whole story and the combined information thus afforded had proved a most fruitful field for speculation and conversation.

A bed for Slider was contrived by spreading over some hemlock boughs a tarpaulin used on the car for covering baggage. A bucket-seat cushion from the car served quite nicely as a pillow. Indeed Chip had not for a long while had so comfortable a resting place, crude as it was.

The plans for the night's sleeping arrangements were seized upon by Phil as an opportunity of finding out whether the strange boy had any knowledge of the recent robbery of the camp. With this in view his remarks about a scarcity of blankets and his inquiries as to where Chip had been managing to find accommodations were adroitly framed. Quite perfectly he succeeded in gaining the knowledge desired, nor did Slider ever suspect that the Auto Boys' suspicions might very easily have been directed toward him.

It was truly pitiable to hear Chip tell how in the night he had stood off a distance in the woods, taking note of the bright campfire of the four friends; how he had smelled their frying bacon when all he had to eat was a little dry bread; how he had been tempted to apply at the camp for food and shelter, but was afraid; how he had spent one whole evening within sight of the cheerful light about the shack, because it was a kind of company for him, and he slipped away and made his bed in the dead leaves beside a log when at last the campfire had quite died down.

Yet very interesting, too, was all that Chip told. One certain fact made clear was that he had nothing to do with the theft of provisions and other items from the camp. When this was fairly plain Phil Way ventured the remark that Murky
