"There! What did I tell you?" gasped Russ. "I'm—I'm going to tell daddy."

"Wait for me! Wait, Russ Bunker! I'm going with you," Laddie cried. "I don't want to stay here and be mur—murdered, too!"

That was an awful word, anyway. Russ crept over the edge of the berth at the foot and dropped down behind the curtain. Laddie was right behind him, and in fact came down first upon Russ's shoulders and then slipped to the floor of the car.

Before they could get inside daddy's curtain—a place which spelled safety to their disturbed imaginations—they heard the moaning voice again groan:

"Mur-r-rder!"

It was an awful choking cry—just like a hen squawked when Jerry Simms grabbed it by the neck and had his hand on the hen's windpipe!

"He's mur—murderin' him all right," chattered Laddie, tugging at Russ's pajama jacket. "Are—are you going to stop it, Russ?"

Russ had no idea of going himself to the rescue of the victim; he had only thought of waking daddy. But now he put his head outside the curtain and looked into the narrow aisle of the sleeping car. The first thing he saw was the colored porter, his cap on awry, his eyes rolling so that their whites were very prominent, stalking up the aisle in a crouching attitude with the little stool he sometimes sat on in the vestibule gripped by one leg as a weapon.

"It's the porter!" whispered Russ huskily.

"Is—is he being mur—murdered?" stuttered Laddie.
