As evening settled over Avebury Manor, the Roxton family gathered around the grand dining table, a spread of exquisite dishes laid out before them. The dining room, with its richly paneled walls and the soft glow of candles, hummed with the chatter and laughter of the family reunion.

After the main course had been cleared away, the family's butler, a dignified figure who had been with the Roxton family for years, entered the drawing room carrying a tray of cookies. With a practiced hand and a subtle smile, he placed the tray on the small table. The cookies, golden-brown and inviting, emitted a homely aroma that instantly caught the attention of everyone in the room.

"Lady Isabelle, Lady Juliette," the butler announced, his voice carrying a hint of affection. "Mrs. Pottridge baked them especially for you."

Isabelle and Juliette's faces lit up with delight. Mrs. Pottridge, the family's esteemed cook, knew precisely how to cater to their tastes, and her cookies were a much-loved treat.

"Oh, how wonderful!" exclaimed Marguerite, her eyes twinkling with pleasure. "Mrs. Pottridge always remembers your favorites."

Juliette reached for a cookie, the familiar texture and taste instantly transporting her back to early childhood memories in the kitchen, watching Mrs. Pottridge bake. Isabelle, too, eagerly took one, indulging in the sweet comfort of the cookies.

Juliette looked around and asked, "Where is Granny? I thought she would come to see us."

"So did we, but for some unknown reason, she's traveled to London." John replied, settling into his armchair.

Isabelle, lounging on a sofa with an air of casual sophistication, dropped a surprising comment. "I think Granny has a boyfriend."

This statement brought a sudden pause to the room, with even the butler momentarily stopping in his tracks.

"What makes you say that?" John asked, raising an eyebrow.

Leaning back, Isabelle said with a hint of intrigue, "The last time we were here, Lord Ashford sent her a telegram, inviting her to London. He's a widower, and she always speaks highly of him."

"Where do you pick up these things?" Marguerite asked, joining the conversation.

Isabelle smirked, "I'm tuned in with this family. I know what's going on."

John, still processing the news, pondered aloud, "Mother in the company of Lord Ashford, at her age?"

"John, people need companionship at all stages of life." Marguerite responded with a soft, understanding smile. "If Lord Ashford brings her happiness, then why not?"

John, finally accepting the idea, nodded slowly. "Yes, you're right. It's just a bit surprising, that's all."

The family's conversation was abruptly interrupted by the sound of the telephone ringing in the grand hall. The butler excused himself and quickly returned, his usual composed demeanor slightly altered.

"My Lady, there's a telephone call for you from London," he informed Marguerite, his voice steady but hinting at the urgency of the call.

A flicker of surprise crossed Marguerite's face as she swiftly rose and made her way to the telephone. The room fell into an anxious hush, with each member of the family exchanging surprised glances, wondering what news the call might bring.

After a tense few minutes, Marguerite returned, her expression a mix of relief, annoyance, and bemusement. The family looked at her expectantly, waiting for her to share the news.

"That was Jessie," Marguerite began. "It seems our mischievous son has managed to find his way to George. They are on the route to Scotland."

Marguerite's gaze met John's, a glint of realization in her eyes. "You don't suppose it is…"

"I'm sure it is." John, nodded gravely, understanding immediately what she meant.

Marguerite's voice dropped to a whisper, her words heavy with implication, "The Loch Ness Monster…"

"We shouldn't waste any time. We should get ready and leave first thing in the morning." John stood up, decisive.

Marguerite's expression shifted to one of irritation. This news had disrupted her plans for a relaxed family weekend. "Just when I thought we could have a peaceful time together..." she muttered, her tone laced with frustration.

Juliette, her eyes shining with excitement, jumped in, "We want to come, too."

"We do?" Isabelle, surprised, questioned,

"Yes. The Loch Ness monster is Challenger's dinosaur, just like mummy and daddy suggested. I would very much like to see it," Juliette declared with determination.

Marguerite looked at her daughters, her expression a mix of exasperation and fondness. "Oh, you are so not going."

"But, why not?" Juliette protested.

Isabelle, her voice tinged with rebellion, folded her arms. "This is so typical. William gets into mischief and is rewarded with an adventure. We stay out of trouble and get left behind."

Marguerite raised an eyebrow. "Since when do you care about lake monsters or any other kind of monsters?"

Isabelle met her mother's gaze, her voice steady. "I don't, but I want to ride in the train and to skip school. Besides, William and George are in so much trouble. I don't want to miss it."

Juliette's eyes sparkled. "That's just Isabelle. I want to go because I really want to see a dinosaur. After horses, they're my second favorite animal in the whole world!"

John looked at his daughters, his expression torn between affection and concern. "Girls, this isn't a holiday. It could be dangerous, and your mother and I need to handle this without worrying about you two."

"Daddy, please. If you leave us behind, I'll never be happy again," Juliette pleaded.

John tried to console her. "Darling, I promise, we'll have a camping trip when we return. What an adventure that will be."

Isabelle smirked. "You are so cute when you're this naive." She took his arm and looked directly into his eyes. "We're seven, not stupid."

John shared a look with Marguerite, amusement twinkling in his eyes. "She's definitelly your daughter."

Juliette, earnest and determined, said, "Just give us a chance to prove we won't be any trouble."

Marguerite and John exchanged glances, seeing their own adventurous spirits reflected in their daughters. The tension in the room was palpable.

Finally, John relented. "Alright, you can both come, but you must behave and listen."

Juliette rushed to hug him. "Thank you, Daddy!"

Marguerite shot John a skeptical look. "John, are you sure?"

John reassured her. "Normally, I wouldn't agree, but Scotland is safe enough. We will stay in one of those charming little inns. It'll be fine, and they'll be out of harm's way."

He then turned to the butler, who stood poised at the entrance of the room. "Charles, would you be so kind as to ring our townhouse in London? Inform the staff of our arrival and arrange accommodations at a hotel or inn in Scotland near Loch Ness. Something comfortable and family-friendly."

Charles nodded promptly. "Of course, my lord. I shall see to it right away."

John gave him a nod of thanks, turning back to his family, ensuring everyone was well-prepared for their impromptu trip to Scotland.

Several days later on the train to Scotland…

Inside the gently rocking train compartment, the Roxton family sat closely together. Marguerite, with nimble fingers, was braiding Isabelle and Juliette's hair, while John looked at them with a pleased grin.

Marguerite caught his eye and, with a knowing smile, remarked, "You're enjoying this, aren't you? I believe you always wanted a family of adventurers."

"Well, my dear, I must admit there's a certain thrill in sharing the wonders of the world with those I love the most." John replied warmly.

The girls, catching onto their parents' exchange, giggled, their young hearts eager for the thrilling tales that lay ahead.

Marguerite, her expression turning serious, glanced at John. "We really need to have a long, serious talk with William. He can't keep acting so recklessly."

John's face grew solemn as he nodded. "Absolutely. He needs to learn the consequences of his actions. We'll make sure to set clear boundaries."

"And we need to speak to George as well. Why on earth didn't he destroy the creature when he had the chance?" Marguerite added, frustration threading through her voice.

Isabelle asked, "Daddy, are you going to kill the creature?"

"No, he won't!" Juliette's eyes widened, and she quickly interjected, "It's not its fault for being in the wrong place. It's completely innocent."

Isabelle rolled her eyes, "Yeah, it's all George's fault. He brought a dinosaur to England and dragged William to Scotland. He's in for a rough time when we get there."

Marguerite shot her a stern look. "Isabelle, Don't call him 'George'. You should address him properly."

Isabelle smirked slightly, "But you call him George."

"That's different. I'm an adult and I've known him for years. You still need to show respect."

Juliette asked with fear, "Daddy, you're not going to hurt the dinosaur, are you?"

John, trying to defuse the tension, replied, "Of course not, darling. We're not on this journey to harm anyone. Our goal is to understand the situation and find the best way to handle it."

Isabelle remarked with a hidden smile. "Veronica and Abigail are going to be beside themselves when they find out."

The train continued its journey, carrying the family closer to the unknown, their spirits alight with anticipation and a sense of togetherness.

As William and Challenger stepped into the dimly-lit cave, the air around them was thick with mystery. Before them, the underground waters of Loch Ness rippled gently, and there, emerging from the shadows, was the creature — a living relic from a bygone era. The gentle light illuminated its features, revealing the graceful lines of a plesiosaur.

Challenger observed with a mixture of fascination and respect as the creature moved, its eyes revealing a depth of intelligence that went beyond mere animal instinct. William, drawn by its presence, approached the water's edge.

Challenger noted with keen interest, "She's a female, and remarkably, she's showing signs of intelligence and comprehension."

However, as Challenger was noting down his observations, William caught sight of a fleeting shadow darting behind one of the larger rock formations. Without thinking, he gave chase. The winding tunnels and dark corners played tricks on his eyes, but his agility and determination proved successful, and he soon cornered the shadowy figure, revealing a young boy. This boy, slightly smaller and younger than William, had untamed, messy hair that framed a face dotted with freckles, especially concentrated across his nose. His blue eyes, wide and alert, flickered with a mix of fear and curiosity as he met William's gaze.

"Who are you?" William demanded, slightly out of breath.

"Name's Roger," the lad replied, his eyes defiant but also sizing William up, "What's it to ya?"

William's guard slightly eased, noting the lack of threat Roger presented. "What are you doing here?"

Roger, squinting slightly, seemed to measure how much to reveal. "This be ma secret spot. Found Nessie here a couple o' years ago. She's ma pal."

Challenger, catching up to them, raised an eyebrow in surprise. "You've been visiting this creature for years? Alone?"

Roger nodded, his pride evident. "Aye. Thought she looked like a lass, so I named her Nessie. We've been mates ever since. I bring her food and hang about with her."

William, intrigued, asked, "And how did you discover this place?"

"Was just wanderin' about one day, and stumbled upon this cave." Roger replied with a cheeky grin. He then asked, "Who are you two, anyway? Ye dinnae sound like ye're from 'round here. How'd ye know about this place?"

William replied, "We have come here to send Nessie back to where she belongs."

Roger, furrowing his brows, asked, "And where might that be?"

Challenger, looking intently at Roger, responded, "To The Lost World…"

Curiosity gleaming in his eyes, William cautiously approached the creature. Raising his hand, he watched in awe as it reached out, touching him gently in a silent moment of mutual understanding.

With a smile playing on his lips, William softly whispered, "Nessie…"

She seemed to recognize her name and a bond started forming between the young boy and the ancient creature.
