“The reason we ask you, Senor Alaroze,” said Ned, still in Spanish, “is because two rascals have just broken into the house and have searched this library. But the strange part is that they did not even have to break in. They simply reached up and pushed the window and it opened under their touch. That does not look as though they found the window barred, does it?”

“I can only say that I dropped the bar across the window before I retired, senor,” replied the overseer, his lips moving uneasily. “Perhaps someone else——”

“Nonsense!” cried Ned, sharply. “The senorita is the only one who sleeps in the house. You and the ranchmen sleep in the bunkhouse. You do not think for a minute that Senorita Mercedes came down and took the bar from the window do you?”

“I regret to say that I do not know what to think, senor,” returned the overseer, quietly enough. The other boys watched him closely, puzzled at his calm and speculating as to what thoughts might be in his mind.

“Well, it is very strange,” remarked Ned, closing the window and dropping the bar in place. When he spoke there was a trace of gloom in his voice, especially when he addressed the overseer. “Be more careful in the future, Senor Alaroze. You alone have the keeping of Senorita Mercedes and her safety.”

“I am worthy of the trust, senor,” retorted the overseer, his eyes narrowing.

Ned looked at his watch. “We’ll have to be getting back, or dad will begin to be worried. I don’t think you will have any more trouble, senorita. If you do, send one of your men to me and I will come as quickly as possible.”

The senorita murmured thanks and accompanied them to the courtyard, where the boys swung onto their mounts. The three ranchmen, seeing that all was well, went back to the bunkhouse, while the overseer, his face hidden in the shadow of the doorway, stood back of the senorita.

She bade them goodbye, thanking them once more. The boys quietly overlooked the fact that she held onto Ned’s hand for a moment longer than seemed actually necessary. They rode away, looking back more than once at the gleaming white ranch in the moonlight, until it was lost to sight.

“I’m very much afraid I don’t trust that overseer,” said Don.
