very sorry if we have disturbed you. Good day, sir”
Mr. Carter’s lips tightened. “If I never see any of those pesky dogs around again, that’s when it’ll be a good day. Now git!”
He thrust the muzzle outwards as he spat out the words, and the boys backed off slowly.
“Turn round,” the man said. “I don’t want you spoiling my lawn!”
Jupiter looked at his two companions and shrugged. With hearts quaking, they turned their backs on the ill- tempered man with the gun and went down the path.
“Don’t run, walk slowly,” Jupiter whispered.
Bob and Pete nodded, wondering when the shotgun blast would come, trying not to panic.
Then they all jumped at the loud sound behind them! “It’s all right, fellows,” Jupiter said. “That was just Mr. Carter slamming his front door.”
The boys turned, saw Jupiter was correct, and ran.
They were halfway down the street before they stopped. They looked back. Nobody was after them. Mr. Carter’s door remained closed.
“Whew!” Bob muttered. “That was close!”
“A shotgun with double-ought ammunition,” Pete said, testing his forehead for sweat. “One more second and that stuff would have ripped right through us.”
“Not too likely,” Jupe said. “The locking bolt was in the off and therefore safe position.”
Bob and Pete glared at him. “You knew that all the time,” Pete said accusingly. “No wonder you acted so calm.”
“I don’t believe Mr. Carter ever intended to shoot us,” Jupiter said. “He was merely acting out his anger. I happened to trigger him off by bringing up the one subject that annoys him. Dogs!”
“I think he’s got another subject now,” Pete said. “People!”
Jupiter pursed his lips thoughtfully. “We’ll have to be more careful the next time we approach Mr. Carter.”
Pete shook his head. “No, sir. The next time you can be careful approaching Mr. Carter all you want. You won’t have to worry about me, because I won’t be there. I forgot to tell you, I have a very delicate skin. It’s allergic to lead.”
“Me, too,” Bob said. “If I’m going to be shot at, I prefer a water pistol at ten paces.”
“There’s a possibility,” Jupiter said, “that Mr. Carter is a far better actor than I give him credit for, and had something to do with the disappearance of the dogs.”
“Sounds reasonable,” Bob said.
“It will be a simple matter now to compare Mr. Carter’s irascible response with our next subject’s.”
“What’s he talking about now?” Pete asked Bob. Jupiter pointed across the street.
“There were two neighbours Mr. Allen mentioned who did not own dogs. We met the first one, Carter. Now we have a few questions to ask the other one, Arthur Shelby.”
A closed metal gate running chest high barred their way. The boys looked over it to the large house set back on the property of Mr. Arthur Shelby.
“Looks okay,” Bob said. “I don’t see a cannon emplacement anywhere.”
Pete inched a little closer to look at the windows on the lower and upper storeys. “I don’t see anybody watching us,” he said. “Maybe Mr. Shelby isn’t home.”
Jupiter stepped forward. “It’s easy to find out,” he said. “All we have to do is go through this gate, and — ”
He stopped, open-mouthed. His companions gaped too. The gate had opened without Jupiter touching it.
“How did you do that?” Pete demanded. “You developing magical powers?”
“Maybe the wind blew it open,” Bob suggested.
Jupiter shook his head. He held out his arms, stopping his companions from advancing, and stepped back. The metal gate swung shut.
Jupiter took a step closer. The gate opened.
“A very simple explanation,” he said. “The gate works on an electronic seeing-eye principle. You’ve all seen that at airports, supermarkets and other modem buildings.”
Pete looked at the gate sceptically. “Sure I have,” he said. “Only I’ve never seen one in a private house before.”
“Any sign of progress and modernity is a good sign,” Jupiter said cheerfully. “The fact that Mr. Shelby uses such a device on his gate shows he is not superstitious or hidebound by convention. Just the kind of person we want to talk to, especially about such an unlikely topic as a dragon in the neighbourhood.”
He stepped through the gate and the other boys followed. Off to the side of the path, the boys saw a large, ornate sundial set in the centre of the lawn. Ahead of them was a large flower laden trellis. They walked under it.
Suddenly the trellis dropped.
The boys stopped, bumping into each other. The front part of the trellis had dropped in front of them. Behind them, the back part of the trellis hissed downwards with a slight clanging sound, barring their retreat.
They were trapped in a huge metal cage decorated with flowers!
“I hope this is only a joke,” Jupiter said, licking his lips nervously. “It’s like a portcullis.”
“What’s a portcullis?” Pete asked in a panicky voice.
“It was usually a large, heavy iron grating suspended by chains and lowered between grooves to bar the gateway of a castle or fortified town,” Jupiter explained.
“I’ve seen pictures of them in old books at the library,” Bob said excitedly. “It’s usually the last defence after you cross the moat of the castle.”
“I don’t remember crossing any moat,” Pete complained fretfully.
There was a slight hissing sound, and as suddenly as it had fallen, the trellis lifted above their heads. The boys looked at each other.
“I think Mr. Arthur Shelby has a keen sense of humour,” Jupiter said, relieved. “Let’s go.”
He took a step forward and Pete grabbed his arm. “You’re going the wrong way, Jupe,” he said. “Maybe they don’t want us in this castle.”
Jupiter shook his head, smiling. “First an automatic-opening gate. Then an electronic controlled trellis. Mr. Shelby seems to be unusually preoccupied with scientific gadgets. It would be a shame not to meet him.”
Jupe moved forward again and his companions followed reluctantly. He grinned as he stepped up and pressed the doorbell,
“Yow-wh!” he yelled, and leaped back, shaking his arm. “That doorbell has an electric charge on it! I got a shock!”
“Okay, I’ve had enough of this Mr. Shelby’s jokes,” Pete said. “I vote we call off the interview with this joker right away.”
“I’m with Pete,” Bob said. “I’ve got a funny feeling Mr. Shelby is trying to tell us he doesn’t want us here.”
“I don’t think so,” Jupiter said. “He’s testing us. He’s put us through a sequence calculated to scare us off.”
As if in answer to Jupiter’s reasoning, the front door clicked and swung silently open.
“Neat,” Bob said admiringly. “He’s got this place bugged all around.”
The boys cautiously stepped over the threshold. The interior was dark and quiet.
Jupiter cleared his throat, trying to speak with confidence. “Good day, Mr. Shelby. We are The Three Investigators, calling at the suggestion of your next-door neighbour, Mr. Allen. May we come in, sir?”
There was no answer. Then faintly they heard a slight flapping sound. It came closer, and they heard it more distinctly. It appeared to be coming from high in the gloomy interior of the house. Suddenly they froze. A huge, dark form was hurtling towards them with a shrill whistling sound.
A big, black, hawklike bird, screeching fiercely, its sharp beak open, cruel talons outstretched, and eyes blazing madly, swooped down on them!
