said. “We really can’t afford Betsy Ross coins. We might need our money for transportation and lunch.”
“Oh, right.” The youngest Alden let out a sigh.
“Never mind, Benny,” Violet said, as they stepped outside. “I have something exciting to tell you.”
“What’s going on, Violet?” Jessie asked.
Violet answered by holding up the postcard. “It’s the Fireman’s Museum!” she cried, her eyes sparkling.
Jessie looked puzzled. So did Henry and Benny.
“What’s going on, Violet?” asked Henry. He could tell by the look on his sister’s face that something was up.
“Don’t you get it?” Violet asked. Then she recited the latest riddle from memory. “Up a ladder, down a pole, look for an arrow high and low.”
Jessie’s face lit up. “Firemen climb up ladders and slide down poles!” She gave her sister a high-five. So did Henry and Benny.
“Violet, you’re a genius!” said Henry.
“Not really,” Violet said modestly. Andy gestured to her and she held the postcard up to the camera. “When I spotted the postcard, it just popped into my head.”
“We’ll find that arrow in no time,” said Benny. He rubbed his hands together with excitement.
“Good news,” said Henry, who was already checking out the new map. “Looks like the museum’s right here in the historic district.”
With that, the Aldens set off with Andy. After a few blocks, Henry couldn’t help noticing that Jessie kept looking over her shoulder. He could see that something was troubling her.
“What is it, Jessie?” he asked her.
“I’m not sure,” Jessie answered. “I just have the strangest feeling somebody’s following us.”
“Somebody is following us,” Henry pointed out. “Look!”
Jessie glanced back at Andy. His camera was propped up on one shoulder as he filmed from a short distance away. “Yes, I’m sure that’s all it is,” she said, smiling a little. Still, she couldn’t shake the feeling there was somebody else was following them, too.
It wasn’t long before they arrived at the Fireman’s Museum—a three-story brick building with arched doorways for the fire engines to go in and out. While Andy waited in the sunshine, Henry, Jessie, Violet, and Benny hurried inside.
They found the museum filled with all kinds of old-fashioned fire equipment—everything from horse-drawn fire engines to antique axes. There was even a brass pole that went all the way from the first floor to the third floor. But they didn’t have any luck finding an arrow.
Henry gave Andy the thumbs-down when they stepped outside again.
“I was so sure we were on the right track,” said Violet. She let out a sigh as she sat down on a nearby bench.
Jessie poured lemonade into Benny’s cracked pink cup. “It was a good try.”
“But if we can’t figure out the first riddle,” said Benny, “how can we find the second one?”
Violet sighed again. “That’s a good question.”
“I just wish we—” Henry suddenly stopped talking in mid-sentence. His mouth dropped open.
Violet turned to her older brother. “What is it, Henry?”
“This is a one-way street!”
“What’s wrong with that, Henry?” Benny wondered.
Henry pointed to a street sign beside the Fireman’s Museum. It was an arrow pointing one way!
The four children raced over to the pole with its one-way arrow on top. Andy was right behind them, his camera propped on one shoulder. Benny was the first to notice the message printed in yellow chalk on the pavement.
“What does it say?” he wanted to know. The youngest Alden was just learning to read.
Henry read the words printed around the pole.
“It makes no sound
but its words ring true;
crack this case
and win round two.”
“I wonder what it means,” Benny said.
“And where it’s leading,” added Jessie, tugging a small notebook and pencil from her back pocket.
While Jessie made a copy of the riddle, the others looked at each other, baffled. Even Andy walked back to the
