“I’m sure it will,” said Bob, who had told his uncle the whole story. “Of course there are some points that seem pretty hazy—especially about this Rod Marbury—how he could be around, attack Hiram on the road and get in his cabin without being seen either time. And that trick of getting the key back in the locked room—that is a puzzler!”

“There must be some secret about the old log cabin,” ventured Mr. Dexter.

“A secret! I’ll say there is!” declared Bob. “But I’ll find it!”

Having arranged with his uncle to get time off from his work in the store, which work he had promised to do since there was no school for a time, Bob began to lay out some plans. Most of all he wanted a talk with Hiram Beegle, to clear up some points.

“I want to know more about this mysterious Rod Marbury,” said the lad to himself. “When Mr. Beegle gets better he can talk more about what happened just before he was stricken.”

The next day Bob went to see the log cabin hermit at the home of Tom Shan, but Mr. Beegle was still a bit weak and uncertain in his mind, and the physician forbade any one bothering him with vexing questions.

“Those two chiefs of police have been here,” said Tom to Bob, “but they didn’t find out much, and I guess they never will.”

“Well, I’ll be around again to-morrow,” said Bob, as he took his leave, followed by a friendly smile from Hiram Beegle who was slowly improving. He had been knocked out by some sort of gas, or else by something given him to drink, the doctor decided. But the effects were passing off.

On his way back from visiting the chief character in this new mystery that had engaged him, Bob took the road to Storm Mountain and passed near the log cabin. It was deserted and locked, for Chief Drayton still had the keys, though he promised to give them to Mr. Beegle as soon as the latter wanted to get back in his home.

“I wish you could talk,” murmured Bob to the silent logs. “You’d tell me how that key got inside the locked room. As soon as I can I’m going to have a look at that room more closely, and have a talk with Hiram. He’ll know whether there are any secret sliding panels in the walls, through which the key could have been tossed in as it could have been had there been a transom over the door.”
