Alan walked into his frequented café on a quiet afternoon, ready to enjoy a relaxing afternoon. Located on a quiet street, this café is known for its unique décor and delicious coffee. Alan liked the atmosphere and felt that it was a place where he could forget his worries for a while.

He found a window seat and ordered a latte and a slice of tiramisu. Sunlight outside the window shines through the green leaves on the tabletop, forming dappled light and shadow. Alan picked up the coffee cup and tasted the mellow coffee, feeling happy.

Just as he was starting to savor the dessert, he noticed a mysterious woman walking into the café. The woman's long hair was fluttering, and her bright eyes shone with wisdom. Her eyes wandered around, as if looking for something. She wore a long dark blue dress with delicate embroidery and an air of mystery.

Alan couldn't help but look at it a few more times, and the woman noticed his gaze as well. She walked over to Alan's desk and politely asked, "Are you Mr. Alan?" Her voice was like a heavenly sound, soft and pleasant.

Alan nodded a little surprised and replied, "Yes, I'm Alan." Is there anything wrong? ”

The mysterious woman sat down in the seat opposite Allen, and she whispered nervously, "I heard that you are a very capable person, and I need your help." There was a murder recently and the police have dropped the investigation, but I know the victim, who is a good friend of mine. I'm sure you'll find the truth. ”

Alan originally just wanted to drink coffee quietly, but the woman's words and look made him intensely curious. He asked, "Why do you believe I can help you?" ”

The woman smiled mysteriously and said, "Because I know your past, you have helped many people find the truth. Moreover, I feel that you are a kind, righteous person. ”

Alan was silent for a moment, then said, "Well, since you believe in me so much, I will try my best to help you." Could you please tell me more about this case? ”

After thanking Allen, the woman begins to tell the details of the puzzling murder. She told Allen that the victim's name was Tom and that he was a successful businessman who was only 35 years old. He owns a thriving jewellery store in the local area, lives a happy and successful business, and has a good relationship with his family. However, one night a month ago, Tom was found dead in his own home, and the cause of death was poisoning. Confusingly, there were no flaws or obvious traces at the scene, and Tom did not leave a suicide note.

Although the police have investigated the scene, they have not found any leads. They thought it might be a suicide, but the woman was convinced that Tom would not kill himself. She tells Alan that Tom seems to have been embroiled in some strife lately, but there are no more details. She suspects that the feud may be related to Tom's death and hopes that Alan will investigate further.

After listening to the woman's description, Alan began to take a keen interest in the case. He decides to accept the assignment and help the woman find the truth about Tom's case. He told the woman to give him some time and that he would do his best to investigate the case.

The woman looked at Eren gratefully and said, "Thank you, Alan." I knew I had found the right person. Please be careful, we don't know what's behind this. ”

Eren assures the woman that he will find an answer for her as soon as possible. Afterwards, the woman said goodbye to Alan and left the café.

Alan cleaned up his mood and drank the rest of the latte. He knew that in the days ahead, he would face an expedition full of unknowns and dangers. But his heart is full of confidence, believing that he will be able to unravel the mystery and find the truth. He paid for his coffee, left the café, and began his detective journey.

This unexpected encounter sets Alan on a thrilling adventure
