“I don’t think so, but there may be.”

The four youths walked through the snow in the direction of the mansion, which was set among some heavy trees.

“Hello, what is that, an animal track?” asked Jack, pointing to a trail among the trees.

“Looks more like human footprints to me,” replied Pepper.

“Then somebody must be here.”

“Funny the trail leads from the side fence,” came from Andy.  “If it was some person who belonged here why wouldn’t he come from the road or the dock?”

“Maybe it was easier to come that way than by the road, right after the snow fell,” suggested Pepper.

They walked forward to the mansion and saw that the trail led to the back door and then around to a side window.

“Hello!  I don’t like this!” exclaimed Jack.  “What would a person be doing at the side window?”

“Try the window?” suggested Fred. They had already tried the door, to find it locked.

Jack stood on a flat rock that was handy and took hold of the lower sash.  Much to his surprise it went up with ease.

“It’s open!” he exclaimed.  “Do you know what I think?  I think somebody came here and got into the house by this window!”

“A tramp, perhaps,” said Fred.

“Or a burglar!” vouchsafed Andy.

“Do you think he is in the house now?” asked Pepper.

“That is something for us to find out.  If he is, we must catch him and turn him over to the authorities!”

“Have we a right to enter the house?” questioned Andy.

“I am sure Mr. Ford would want us to do so, Andy.”

“I guess you are right.  But be careful, Jack, that fellow, whoever he is, may be a desperate character.”

“Perhaps he isn’t here now,” said Fred.  “He may have looted the place and skipped.”

“I’ll soon see,” cried Jack.  “Pepper, do you want to go in with me?  You other fellows might stay on guard.”

“Sure, I’ll go in,” answered The Imp.

In a moment more the two cadets stood in the sitting-room of the mansion.

“Better not make too much noise,” whispered Jack.  “If he is here we may be able to take him unawares.”

As the sky was overcast that afternoon it was rather dark in the mansion, and the cadets could see but little as they made their way from one room to another.  They were just entering the dining-room when Pepper’s foot struck something and sent it spinning across the floor.

“What’s that?” asked his chum.

“I don’t know—­sounded like a spoon or a fork,” was the reply.  Pepper walked forward, bent down, and felt around.  “Yes, it’s a silver fork!”

“It made as much noise as if it was a dozen of ’em!” murmured his chum.

“Hark!”

Pepper put up his hand and both listened intently.  They had heard a noise, as of footsteps overhead.

“Somebody is up there!” whispered Jack.
