“You’ll have to go!” Tom’s voice insisted. “There’s not a man in the harbor who knows the tricks. They’re all out in boats looking for that sub.”
“All right, Tom. I’ll meet you at the dock.” She hung up.
“Marie!” she commanded. “You keep the switchboard. Rosa, get your coat and come with me.”
One minute more and they were joined by Lieutenant Warren, who somehow had learned the news. Then all three raced for the dock.
Norma was faster than the others. She arrived in sight of the dock just in time to see a ghostly figure emerge from the shadows, leap at Tom, who was just coming to the dock, and deal a heavy blow with some blunt instrument square on his head. Without a sound, Tom dropped like an empty sack.
Norma had seen that white-robed figure before. She had battled with it and won. Not the least afraid, without warning, she landed upon it with a head-on blow that sent it crashing against a wall. It crumpled into a white heap and lay there like a pile of snow.
“Wha—what happened?” Lieutenant Warren panted, as she came racing up.
In a few, well-chosen words, Norma told her. “It’s terrible!” she groaned. “Tom is out for keeps. Per-perhaps he’s dead. We can’t go!”
“We can go!” Rosa insisted stoutly. “I can pilot the plane as well as Tom could!”
“What do you think?” Norma turned to the Lieutenant.
