He grabbed hold of the covering and the newcomer was soon uncovered.
"Now, then, who are you?" asked Donald again.
"I"ll show you who I am if I get hold of you," was the uncivil answer, and an arm shot out.
"Now look here," said Donald, "if you don"t stop that I"ll let daylight through you. We are in a bad box and the only thing to do is to make the best of it."
"We?" exclaimed the newcomer. "Why do you say we?"
"Because I am a prisoner the same as you are. Now, who are you?"
"I"m Lieutenant Grimes of the general"s staff. Who are you?"
"I am Donald Mackay, on a special mission for Gen. Funston."
"How did they get you?"
"Kidnaped me on the street. How did they get you?"
"Same way. I had just left the general"s quarters."
"I can see that some one might want to capture you, lieutenant, but I cannot see what they want of me."
"How long have you been here?" asked the lieutenant.
"About half an hour. By the way, are you armed?"
"No; they took away my weapons. How about you?"
"I have my automatic. I"d have used it when you came in, only you were dumped in so suddenly."
"What do you suppose the game is?"
"I don"t know; but we"ll find out. I"ve been in tighter places than this--but no hotter," after a pause.
"Have you tried to get out?"
"Yes; but it was too hot work. The door seemed pretty strong."
"Perhaps the two of us might force it," suggested Grimes. "I"m a pretty husky chap."
"We might try," replied Donald. "The place is so narrow we can get a good brace."
They put their feet against the opposite wall and pushed against the door.
"We"ll never make it that way," said the lieutenant. "We"ll have to throw ourselves at it."
"Not much room for that, Lieutenant, but you give the word and we"ll have a try."
Getting their bearings as well as they could in the dark, they drew themselves back and then literally threw themselves at the door. It gave way with a snap and both fell to their feet on the outside.
Quick as a flash they were on their feet, Donald with his weapon ready for instant action.
But there was no one in sight.
"That"s mighty funny!" exclaimed the lieutenant. "Lock two strong men up in a place like that and not guard it."
"It"s a mighty good thing for us they didn"t," laughed Donald. "I wonder where we are?"
He glanced about the room which was dimly lighted by a couple of lamps, fastened to the wall by brackets. It was well--yes, elegantly furnished. At one side of the room was the closet out of which they had just emerged, while at the opposite side were three doors. On a third side were two windows and the fourth side was a plain wall.
"Not a bad-looking place," observed the lieutenant.
"Not at all," echoed Donald, "and there seem plenty of means of exit."
"Sure, my boy; and if it"s all the same to you, we"ll go. The sooner I get back the quicker I"ll be able to start something in this direction. Come on!"
They crossed over to the doors and tried the first one. It was locked. They tried the second and it opened into another closet.
"Three times and out," laughed Donald as he took hold of the k.n.o.b of the last door.
It yielded to his touch and he opened it gently. Then he quickly and quietly closed it.
"What"s up?" asked the lieutenant.
Donald put his fingers to his lips.
"How many?" queried Lieut. Grimes.
"Three," was the whispered response. "Let"s hear what they have to say."
He opened the door a crack, through which they could see three men seated at a table. One wore the uniform of a Mexican officer, the other was dressed in Mexican costume, while the third was unquestionably an American, although they could only see his back.
"I have carried out my part of the agreement," the American was saying, "and now I want my money."
"How do we know you have?" asked the officer.
"Haven"t I put Gen. Funston into your hands?"
"We are not sure it is Funston," said the other.
"Then bring him out and look at him. You know the general when you see him, don"t you?"
"I think so, although I"ve never seen him but once."
"Well, that is he, all right," declared the American.
Donald turned and looked at his companion. Then he chuckled.
