Delphini stood in front of the imposing Riddle Manor, her heart pounding. The rumors surrounding this place were endless, and a sense of dread hung in the air. But she had a mystery to solve.

After taking a deep breath, Delphini pushed open the iron gates and made her way to the front door. She was greeted by the stern housekeeper, Mrs. Gerard.

"I'm here to investigate the recent disturbances," Delphini calmly explained. Mrs. Gerard simply nodded and led her into the gloomy mansion.

As she walked through the dark corridors, Delphini felt a sense of unease. The air was heavy and cold. Every object in the mansion seemed to hold an eerie story.

She was led to the library, the place where the disturbances were reported. Delphini scrutinized the room with a professional gaze.

Books scattered all around, a ladder fallen to its side, and a picture of the Riddle family tilted oddly. She took note of these peculiarities.

She asked Mrs. Gerard to leave, promising to handle the situation. Alone in the library, Delphini carefully began examining her surroundings.

She spent hours examining every possible corner of the library. Nothing seemed out of the ordinary until she noticed a peculiar book.

It was a history book on the Riddle family. Delphini flipped through the pages, her interest piqued by one particular passage.

It hinted at a secret chamber hidden within Riddle Manor. Intrigued, Delphini continued to read, seeking more clues.

An ancient riddle hinted at unlocking the hidden chamber. Delphini copied it down, eager to solve it.

She spent the night in the library, wrapped up in the riddle, until dawn colored the sky with hues of pink and orange.

When she finally solved the riddle, excitement bubbled within her. It pointed to a specific book within the library.

With a pounding heart, Delphini pulled the book from its shelf, causing the bookcase to shift, revealing a secret door.

With a torch in hand, she stepped into the unknown, ready to uncover the centuries-old secrets hidden within the manor.

Inside, she found a room filled with antique artifacts, but one object caught her eye - a cryptex.

She examined the cryptex carefully. It had an inscription, another riddle that needed solving.

Delphini pondered over the riddle for hours, using the clues scattered within the chamber to solve it.

Upon solving the riddle, she carefully aligned the symbols on the cryptex and with a satisfying click, it opened.

Inside, she found a parchment. As Delphini unfurled it, her eyes scanned the content. It was the lost will of the Riddle family.

This discovery was the missing piece that would solve the mystery of the Riddle family. Filled with excitement, Delphini rushed to share her findings.

She briefed Mrs. Gerard about her discovery, who expressed relief and gratitude towards Delphini for uncovering the lost will.
