Rusty #4

When Rusty, Tubby, and Spunky discover a cave behind Rusty's home, they transform it into the perfect secret clubhouse—complete with bunks, a natural chimney for cooking, and a generator to power a shortwave radio set. Their celebration is cut short when uninvited guests arrive: first a rival gang looking for trouble, then three fugitive criminals seeking a hideout. What starts as a prank spirals into an unexpected confrontation that tests the boys' courage and resourcefulness.

Spunky's day takes a wild turn when a mischievous pup chews up his circus pass, forcing him to scramble for the 75¢ to buy a new ticket—but his attempts to earn the money keep going hilariously sideways. When a circus detective named Clancy offers him a deal to borrow the dog, Spunky gets his chance to see the show, only to find himself caught in a comedic tug-of-war over who the pup really belongs to.

When foreign agents threaten to steal the ultra-advanced XP-140 interceptor, Colonel Rogers calls on Mark Legion—master of disguise—to impersonate the spy posing as an Air Force pilot and uncover the theft plot before it unfolds. As Mark infiltrates the operation during a public demonstration, he'll need every trick in his arsenal to stay one step ahead of the enemy agents and protect one of the country's most secret weapons.

Rusty Adams, a young radio enthusiast, is on a seaside vacation with his injured father when a desperate situation forces him to put his short-wave skills to the test. After calling the Coast Guard for help, Rusty finds himself rescuing the crew of a burning ship—only to discover they're criminals commandeering his vessel to escape to Cuba. Now stranded with dangerous fugitives and his father's life hanging in the balance, Rusty must rely on his wits and his radio to find a way out of this unexpected adventure.

Clancy the clown detective springs into action when the circus's tent stakes vanish on the morning they're supposed to set up the big top, leaving the show in jeopardy. His investigation leads him on a clever trail through town that uncovers exactly where those stakes have ended up. It's a lighthearted whodunit that proves even a clown can crack the case.

Rusty and his friend Tubby dream up an ingenious plan to catch the bank robbers plaguing Center City: they build a tiny radio transmitter disguised as a stack of money and slip it into the hands of a teller, allowing the police to track the thieves' escape. When a robbery happens during a dress rehearsal and the boys pick up the signal on their own receiver, they can't resist following the trail themselves—leading them straight into danger at the robbers' hideout in the woods.
