Lisa and Callie were introduced and the attack on Lisa was described, Frank gave Joe and Lisa the bad news about what had happened to Callie's notes.
"Poor Chet," Callie added. "He couldn't even eat his pizza afterward. He just left it and went home."
"A total disaster, huh?" said Lisa, looking at the remains of the piece of paper. "Can't you dry it out or something?"
"I don't think there's any use trying," said Callie. "The ink is completely smeared."
"Well, there goes our last link to the mugger. We have nothing to track him down with—and he has no reason to go after Callie anymore." Frank glanced around. "I hope."
"It's a tough break," said Lisa sympathetically. "Does this mean you're giving up?"
Callie's voice was indignant. "Not on your life. We'll get that guy yet. And we do know that he's somehow connected to the mailman I bumped into yesterday." Callie quickly explained her theory about how the black book had gotten in her bag to Lisa and Joe.
"If I can do anything to help, let me know," Lisa said.
"Sure. Thanks." Joe smiled eagerly. "That's a great idea. Welcome to the team."
"Don't forget, I'm interested in this case, too. That guy has gone after me twice now," Lisa said.
"That's right—and there has to be a connection," said Frank. "You and Callie must have something in common that we don't know about."
Joe recognized the gleam in his brother's eyes.
"Stand back," Joe said with a grin. "You're about to see my brother's famous brain go into action."
It took just under a minute for Frank to nod to himself.
"I think I've got it," he said, and the others leaned forward. "Callie picked up the black book at City Hall yesterday just about the time that the city manager committed suicide. And Lisa came into town to investigate any scandal that might surround that suicide. Somebody out there doesn't want his connection to the suicide known."
Lisa nodded. "That makes sense."
Joe said, "Now you see how Frank and I operate. He's the brains, I'm the muscles."
"All the way up to and including your head," Callie said. The show that Joe was putting on for Lisa's benefit was simply too much.
"Come on you two," said Frank. "We've got better ways to spend our time right now." Then he asked Lisa, "Did anyone know you were in town to investigate the suicide?"
"I don't think so," she began, then stopped herself and said, "Yes. I did stop by police headquarters to see if there were any new developments, and I told them I was working on an article."
"Then somebody in the police department could have . . ." Frank let his voice trail off, not wanting to complete the thought out loud.
But Lisa didn't hesitate. "If we are on to a case of civic corruption, some of the members of the police force might be involved." She bit her lip. "That means we'll have to conduct this investigation on our own. We can't afford to risk a leak to our mugger."
"Lisa's right," said Joe. "Anyway, Chief Collig would never buy a story like ours, especially since we don't have any hard evidence."
"Yeah," said Frank. "Too bad Riley's away. He would be helpful. But are we agreed that once we do get hard evidence, we turn it over to the authorities?"
The other three nodded.
"The only trouble now is that we can't ask the police for any news about the suicide," said Callie. Then she said, "But we do have one good source of information."
"Who's that?" asked Lisa.
"Liz," said Callie. "Liz Webling. Her father is the editor of the Bayport Times. She works there after school, and she always gets the latest news before it's printed."
"But can you trust her to keep quiet?" Lisa asked.
"She's my best friend," said Callie. "All I have to do is explain the situation. She'll be glad to help. I'll give her a call right now."
"I don't know about this," said Joe after Callie crossed the room to make the call. "You know how some girls like to talk. Can we really trust Liz?"
"Trust Callie," said Frank quietly, and everyone fell silent, waiting for her to
