Free Comic Book Mystery by Gertrude Chandler Warner

CHAPTER 1
The Missing Comic Book
    Six-year-old Benny Alden put down the Captain Fantastic comic book with a satisfied sigh.
    “That was cool,” he said. “Especially when Captain Fantastic jumped over a building to catch the bad guys.”
    “It was a good story wasn’t it?” said ten-year-old Violet. They had read the comic together.
    Jessie, who was twelve, glanced out the window of the boxcar.
    “It’s stopped raining,” she said.
    “Let’s ride our bikes downtown and see if the new issue of Captain Fantastic is out yet,” Henry suggested.
    The boxcar was a great place to spend a rainy afternoon, but the Alden children were glad to be outside.
    When their parents had died and they had no home, Benny, Jessie, Violet, and Henry had lived in the abandoned boxcar in the woods. But then Grandfather Alden found them and took them to his big house in Greenfield. Grandfather had the boxcar towed to the backyard so the kids could use it as a clubhouse.
    Now the Boxcar Children rolled their bikes out of the garage and pedaled to the town square. They locked their bikes in the rack and walked into a small shop called Comic World.
    “Hello,” said a young man who was chewing gum. “What can I do for you?”
    “Is the new Captain Fantastic here yet?” asked Benny.
    “Just came in yesterday,” replied the clerk, putting the comic on the counter.
    As the oldest, fourteen-year-old Henry carried their pooled allowances. He paid for the comic and gave it to Benny.
    “Need any back issues?” the young man inquired. “Comic World sells used comics as well as new ones.”
    “We have every issue except one,” Jessie said. She kept their collection organized by issue number.
    The clerk nodded. “I bet I know which one you’re missing. Number nine, right?”
    “How did you know?” asked Violet. She liked comics for the art. She was thinking about becoming an artist someday.
    “There’s a mistake in Captain Fantastic number nine,” said the clerk, popping his gum. “You know that purple suit and green cape he always wears? Well, in the second story of number nine, the cape is orange. ”
    The young man leaned on the counter. “The mistake makes it valuable. Collectors are hanging on to it. They don’t bring it here to trade or sell.”
    “Will we ever find that comic?” Henry said. “We’d like to have a complete collection.”
    “It’s not impossible to find number nine,” the clerk answered. “There’s an antiques show across town in the Greenfield Center. Some out-of-town comic book dealers are there. You might get lucky.”
    The Aldens thanked the clerk, then went outside. Henry said, “The Greenfield Center isn’t far. Let’s ride over.”
    The huge community building was packed with booths and dealers selling old furniture, paintings, lamps, rugs, coins, dishes, and books. Crowds of people escaping the rainy day clogged the aisles.
    “Wow!” said Jessie. “It’s like a bunch of little stores in one big store.”
    Violet spotted a display of old comics at a nearby booth.
    “Let’s try there,” she said.
    At that moment, a familiar figure turned away from the booth. He wore a purple suit with a green cape and a black eye-mask.
    “Captain Fantastic!” Benny exclaimed. “He’s real! No, wait. He walks too slowly and he doesn’t have any muscles.”
    “It’s a regular person dressed in a Captain Fantastic suit,” Jessie told him.
    Without saying a word, the masked man handed her a flyer, then strolled down the aisle.
    “What does it say?” asked Benny.
    “It says there’s a meeting of the local Captain Fantastic Fan Club at the library this week,” Jessie said. “And something about a big comic con next weekend in Hartford. What’s a comic con?”
    “I think it’s short for convention,” Henry said. “Comic book fans from all over the world will probably be there.”
    Ahead of them, the Captain Fantastic cruised the aisles, handing out flyers. He stopped briefly and spoke to a
