“You try,” Dusty told Bob.

“What for?” Bob shrugged. “All I’ll get is the same put-down from her.”

“Maybe you’re right.” Dusty did his best to smile. He looked at Jupe. “You mind trying to call her for me?” he asked politely.

Jupe could take animals or leave them. He didn’t care if the burro came to him or not. But he could tell from the worried look in Dusty’s eyes, the way the rancher suddenly gripped Jupe’s arm, that this mattered a lot to Dusty. Jupe was curious.

He freed his arm. “Come here, Blondie,” he called in a bored voice.

The effect was astonishing. The burro’s head swung around instantly. She looked straight at Jupe. Her ears twitched once and then pointed forward.

“I don’t believe it!” Pete said.

“Again!” Dusty whispered excitedly. “Say it again!”

“Come here, Blondie.” This time Jupe’s voice sounded a bit more interested.

The burro strained against the rope that hobbled her front legs and ambled toward Jupe as quickly as she could. She stopped less than a foot away from him. Stretching her neck, she prodded his chest gently with her nose.

“She’s fallen for you!” Bob said, slapping his friend on the back. “How do you do it, Jupe? Three little words and she’s crazy about you.”

Jupe stepped back. The burro’s response to him had caught him by surprise. And Bob’s kidding made him feel embarrassed.

“Stroke her.” Dusty was gripping his arm again. “See what happens if you touch her.”

Out of sheer curiosity, Jupe stretched out his hand and stroked Blondie’s neck. Her ears stood straight up. She rubbed her nose against Jupe’s chest again.

Dusty let go of Jupe’s arm. He was smiling like a man who had just won first prize in a quiz show.

“I bet she’d even let you ride her,” Dusty said. “Go on. It’s okay. Even at her age, she’s a very strong little animal. She can carry you. Easily.”

Jupe hesitated. He didn’t particularly want to ride the burro. But Dusty’s excitement had started a whole train of questions in his mind. Something was going on here that he didn’t understand. As an Investigator, he had to follow every possible lead.

He swung his right leg over the burro’s back and settled astride her. Blondie turned her head and tried to look up at him with her huge soft eyes. Her ears were bolt upright. She seemed to like the idea of having Jupe as her jockey.

“Say, giddyup,” Dusty whispered urgently.

The words stirred a sudden memory in Jupe’s mind.

“Giddyup,” he said. “Giddyup, Blondie.”

He had to hold on to the burro’s neck to keep his balance as she clumsily ambled forward. Memory had given him a clue. He decided to try a little experiment.

“Whoa, Blondie,” he said. “Whoa!”

The burro obediently came to a stop.

“Well, she certainly seems to have taken a shine to you,” Dusty told Jupe as he got off the burro’s back.

“Yeah, it’s your animal magnetism, Jupe,” Pete put in. “That’ll do it with blondes every time.”

“Very funny,” Jupe said. “Maybe I remind her of somebody.” He was looking at Dusty.

“How could you?” Dusty shook his head. “That burro was quite wild when she strayed down here. The only people she’s ever known in her life are me and Ascención. And you don’t look anything like either of us.”

“No, I don’t look like you,” Jupe admitted. He reached up and pinched his lower lip. It was a habit he had when he was trying to figure something out. He claimed it helped him to think.

He was still pinching it half an hour later as he sat on his bunk in the large, comfortable room he was sharing with his two friends. Looking out the window, he could see the field with the shed in it. The white burro was standing close to the fence. She looked toward the house and brayed softly, as though calling to Jupe, wanting him to come back and stroke her again.

“Blondie!” Pete, who was assembling his fishing rod, said suddenly. “Dagwood’s wife. In the comic strip. ‘Blondie’ was one of the answers in that crossword puzzle.”

“Yeah, it was,” Jupe agreed. “But it isn’t just Blondie. There are the other clues too.”

“What other clues?” Bob was unpacking his tote bag. He folded his spare jeans neatly away in a drawer. “Clues to why this blonde finds you irresistible?”

Jupe ignored him. “The words Dusty asked us to say to that little burro just now. They were all answers in that crossword puzzle.”

“Yeah?” Pete said. “Which ones?”

Jupe leaned back against the wall and half closed his eyes.

“Come. Here,” he said. “Giddy. Up. Woe. Not ‘woe’ meaning sorrow and misfortune. But w-h-o-a, Blondie. Meaning ‘stop.’ And Blondie obeyed every one of those orders.”

Bob walked over to his own bunk and sat down. He was frowning thoughtfully.

“You’re onto something, Jupe,” he said. “But when Pete called her, he used some of those same words and she didn’t give him the time of day.”

“I know,” Jupe admitted, sounding as puzzled as Bob. “I realize it’s impossible, but you’d think that little animal had met me before somewhere. She seemed to recognize my voice!”

That night, after a good steak dinner that Ascención barbecued for them, the Three Investigators went to sleep early.

Jupe was awakened a few hours later by a rubbing sound against the window beside his bunk. Raising his head, he saw that Blondie was outside. She was doing her best to push her nose in through the glass.

Jupe grumbled to himself and shook his fist at her, but she wouldn’t go away. If Pete and Bob woke up and saw this, they’d never stop teasing him. Still mumbling, he got out of bed and walked to the door that led straight into the back yard. The moment he opened it, the burro stuck her head into the room. Jupe pushed hard against her chest, trying to keep her out. The little animal was as solid and unyielding as a sandbag. He couldn’t move her. He finally slipped past her and, stepping outdoors, softly called her name.

She turned at once and trotted toward him. In the moonlight he could see that the hobbling rope was gone from her front legs. She was free. If he went back to his bunk, she would probably try to follow him.

You little pest, he thought. How am I going to get rid of you? The only answer seemed to be to lead her back to her own field. He started toward it, then suddenly stopped dead.

He could hear the sound of Spanish from the back porch at the far end of the house. A man’s voice and then a woman’s. Although Ascención never said a word to Dusty, he had been quite friendly to the three guys at the barbecue. Speaking Spanish to Jupe, he had asked them questions about the United States, talked about the lake, and warned them not to swim in it. He had told them the mountain water was ice cold and no one could last more than a few minutes in it. Jupe instantly recognized Ascención’s gravelly voice now, but he was too far away to hear what the Mexican was saying.

Wondering who the woman was, Jupe moved closer to the back porch. Blondie walked beside him. Jupe stroked her neck to keep her from braying.

The woman was talking now. “You must help me, Ascención,” Jupe heard her say in Spanish. “You know what Rice will do if he finds them. He might even kill them.”

Ascención replied with several Mexican swear words describing the rancher. “All right. I’ll do everything I can to help you,” he promised. “You can count on me.”

The woman thanked him. Jupe quickly withdrew into the darkness as he heard her light footsteps coming down into the yard. He caught a glimpse of her before she vanished around the end of the building.

She had her back to him so he couldn’t see her face. But the moonlight shone briefly on her blond hair.

The burro was rubbing her shoulder against Jupe. From where he was standing he could see that the gate into Blondie’s field was open. He led her through it, closing and latching the gate after him. Then he climbed back into the yard. The burro hung her head over the fence, braying complainingly. Jupe was relieved to see she was no jumper. He went back to bed.
