Eagerly Nann opened it, as it had been written especially to her, and after reading it she exclaimed: “Well, isn’t this queer?”

“What?” Dories, who was consumed with curiosity, exclaimed.

“Dick writes that he told his mother that he had found that upper front room window open and the blind swinging, but she declares that she knows all of the upper windows were closed and the blinds securely fastened. She had been in every room to try them just before she left, and that was what had delayed her so long that, in her hurry, she took the key out of the back door, hung it in its hiding place, without having turned it in the lock. Dick says that he’s wild to get back to Siquaw, and that the first thing he is going to do is to search in that upper room for clues.”

Gib nodded. “That’s what he wrote into my letter. He’s comin’ down Friday arter school lets out, so’s we’ll have more time over to the ruin. Dick says he’s sot on ferritin’ out what that pilot fella does thar.”

Old Spindly seemed to feel spryer than usual and trotted along the sandy road at such a pace that in a very little while they had reached the end of it at the beach.

“Wall, so long,” Gib called when the girls had climbed down from the high seat, but before they had turned to go, he ejaculated: “By time, if I didn’t clear fergit ter give yo’uns the rest o’ yer mail. Here ’tis!” Leaning down, he handed them another envelope. Before they could look at it, he had snapped his whip and started back toward town. The girls watched the old coach sway in the sand for a minute, then they glanced at the envelope. On it in red ink was written both of their names.

“Well of all queer things!” Nann ejaculated. Tearing it open, they found a message: “Today you will know all.

CHAPTER XXIV.
A SURPRISING REVELATION

The girls stood where Gib had left them staring at each other in puzzled amazement. “Well, what do you make of it?” Dories was the first to exclaim. Nann laughingly shook her head. “I don’t know unless this confirms our theory that Gib writes the notes. I almost think it does.”

They started walking toward the cabin. “Well, time will tell and a short time, too, if we are to know all today,” Dories remarked, then added, “That long walk has made me ravenously hungry and we haven’t a thing cooked up.” Then she paused and sniffed. “What is that delicious odor? It smells like ham and something baking, doesn’t it?”
