“Professional spies have ingenious ways of working,” Mr. Evans said. “Anyway, it’s pretty plain now how both the radioisotope and the blueprints happened to disappear. One thing’s equally certain. This is all part of a carefully worked out plan. The job now is to stop that plan—and stop it tonight.”
“Oh, I’m frightened,” Teena said. “Spies, and submarines, and—and—”
“Aw, Teena,” Eddie said, “there’s nothing to be afraid of.” Yet he had to clasp his own hands tightly together to keep them from shaking.
“All right, everybody,” Mr. Evans said, looking at his watch, “within an hour everything will be set up. I’m not free to reveal our plan. However, since you are all involved in this thing, I have no objection to your witnessing the outcome. If an outcome there is. Remember, we’re going primarily on guesses. So, if you want to drive quietly out to the lighthouse, I’ve arranged—”
“Lighthouse!” Eddie exclaimed. “We know Captain Daniels. He’s a good friend of ours.”
“I know,” Mr. Evans said. “I talked to him on the phone. He’s a Coast Guard man, you know. And the Coast Guard is mighty important to tonight’s activity. You might find what goes on out there, and in the bay, extremely interesting to watch.”
“Can Teena and I go?” Eddie asked anxiously.
“Of course,” Mr. Evans said. “Without you two, we wouldn’t have a thing to be working on, would we?”
Eddie flushed with pride.
“Of course,” the FBI man went on, “you will have to ask your parents.”
