“Cassie!” he cried, guardedly. “You told me you had given it up! You told me you’d never use morphine again!”

“Frank!” she whispered, looking abashed. “I know I told you so! I meant it, but I must use it just once more—just to-night. I am not feeling at my best. I’m dull and heavy. You know how much depends on me. If I don’t do well I shall ruin everything. It won’t hurt me to use it just this once. The success of ‘True Blue’ may depend on it!”

“If the success of ‘True Blue’ depended on it beyond the shadow of a doubt, I would not let you use it, Cassie! Great heavens! girl, you are mad! If you fall again into the clutches of that fiend nothing can save you!”

“But the play——”

“Do you think I would win success with my play at the price of your soul! No, Cassie Lee! If I knew it meant failure I would forbid you to use the stuff in that syringe. Here, give it to me!”

He took it from her and put it into his pocket.

“Now,” he said, “it is out of your reach. You must play without it. There goes the overture. The curtain will go up in a few minutes. All I ask of you is to do your best, Cassie, let it mean success or failure.”

CHAPTER XXII.—THE END OF THE ROPE.

The theater was packed. Under no circumstances had Frank anticipated such an audience on the opening night. He felt sure that the advertising given him through the effort of his enemies to injure him had done much to bring people out. Another thing had brought them there. Curiosity led many of them to the theater. They remembered Merriwell’s first appearance in Puelbo and its outcome, and they had not forgotten how, in a speech from the stage, he had vowed that he would bring the play back there and give a successful performance. He had rewritten the piece, and it had been played in Denver to an invited audience, every member of which went away highly pleased. The Denver papers had pronounced in favor of it.

Puelbo people admired pluck and determination. They could not help feeling admiration for the dogged persistency of Frank Merriwell. And they really hoped he would make good his promise to give a successful performance.
