"But there was one incident that may have something to do with the motive for the killing. Caitlin handed Eric another piece of information that had been put together, "The European Children's Music Charity Foundation, chaired by Professor Lucio, launched a musical initiation program called "Children's Voices Unforgettable" at the beginning of last year, and the plan is to select 100 musically talented children in Europe and provide them with master-level training. ”

Hearing this, Chiko asked suspiciously, "Is there anything wrong with this?"

Eric skimmed through the information and explained, "But the program was terminated just three months after it was launched. The reason is that a tabloid reporter revealed that more than 70 of the 100 children selected had received a high level of music education before, and almost all of them came from wealthy families, so there was no need to occupy a place in this charity program. ”

"Is it because of Professor Lucio's secret operations?" Chiko continued.

Professor Lucio was unaware of it, he was only in charge of developing the plan, which was implemented by the sponsors and the Executive Committee. Caitlyn rubbed her temples, "But the decision to terminate the project was up to Professor Lucio. ”

"If so, the motive for the killing remains unclear. Chiko frowned, "It seems that the scene of the crime is still the main clue." ”

"You've been there too, and I'd like to hear about your findings. Eric winked amusefully at Chiko.

Chiko replied with a roll of his eyes unappreciative. Although she was very willing, even desperate, to talk about her discovery, because Chiko didn't want her to play a brute female agent among the four of them forever, she didn't want them to see that she was eager to show herself, because it would be too easy to expose her current cowardice towards the agent profession.

"First, judging from the scene, the fire should have been very large when it broke out, but according to Bob, the flight attendant, after the fire alarm sounded, he rushed into room 303 as soon as possible, and Professor Lucio had already burned to death by then. However, judging by the charring degree of the corpse, the fire broke out at least 5 minutes before the fire alarm sounded, which means that 303's smoke alarm did not sound until 5 minutes after the fire. Chiko carefully grasped the words.

"Is there a problem with the smoke alarm?" asked Caitlyn.

"No, Scott, the purser, has ruled out the issue. Eric added.

"Second, there are only three places in the room where there are burn marks, one in the middle of the room, one behind the door, and one is the ribbon between the first two, apparently Professor Lucio was murdered and set on fire in the middle of the room, and then dragged behind the door. But when Bob entered, he didn't find anyone, so how did the killer get out and control the fire?"

"Murder in a closed room. Caitlin smiled.

"Thirdly, whether it is the carpet in the room or the human body, it contains compounds of C and H, and when burned, small particles of hydrocarbons are produced, so there should be black smoke forming. Why didn't the whole carriage – including us – notice anything, and how did it do it. There is also Professor Lucio, a middle-aged man in his forties, and there is no trace of struggle at the scene. And, according to Scott, the purser, he did not order any food or drink, thus ruling out the influence of foreign drugs. So how was he quietly killed without resisting. At this time, Chiko felt that she had found the confidence she had lost for a long time.

"Silent murder in a closed room. Caitlin's thin eyebrows rose slightly, and she showed great interest.

Chiko stared into Eric's eyes, hoping for an affirmative answer. Facing Chiko's gaze, Eric suddenly felt at a loss, he couldn't help scratching the skin in the corners of his eyes, and stopped talking. The woman who had been fierce to him suddenly cast such an indescribable gaze made him feel an itch in his heart.

At this moment, there was an untimely knock on the door. Eric replied as if grasping at a life-saving straw, "Please come in." Pushing the door in, it was Scott, the purser, who greeted respectfully: "I have prepared the spacious room you wanted, and the passengers in the three rooms have promised to cooperate with your work." ”

"Thank you very much. Eric stood up.

"That's my duty. Scott glanced at the strange Caitlin and the drunken Leonardo. Two beauties in the city, a scruffy detective and a snoring drunkard, reminds him of pole dancing in waltzes – an inexplicable combination.

Eric and Chiko then followed Scott to the first car. Scott had skillfully put together a large square table with exactly one room occupying passengers on each side, and the last side that was left vacant with his back to the direction of the train was left for them.

Eric sensitively noticed that none of the other four cabins were full, except for their own standard room. Sitting on their left were the passengers in room 304 next to them - two middle-aged men with ordinary appearances, Jamie and Vincent, and on their right were the passengers in room 302 - two middle-aged women, one fat and one thin, Ollie and Jonny, and Ollie, the fat woman, frowned subconsciously when she saw Eric and Chiko, apparently she recognized these two as men and women kissing in the corridor, which also made Chiko's cheeks fly two red clouds. In the end, there was only one man in a suit and leather shoes sitting across from them, Sandys. Scott and Bob sat on the sidelines like jurors in the courtroom.

Before Eric could speak, Fat Woman Ollie took the lead: "Mr. Scott, I understand that you want to solve this matter as soon as possible, but are you sure you have found the right person?"

Ollie's question really made Scott very difficult. In fact, Scott has no convincing evidence to prove whether Eric is reliable, and he even begins to regret that he trusted the curly-haired scruffy detective in front of him with just a business card. But now that he was too strong to ride the tiger, he could only swear and promise: "Don't worry, Lady Ollie, I have seen what he is capable of." What's more, if there's a chance to catch the killer as soon as possible and keep us safe, why don't we try it? And it doesn't cost us anything. Scott's words were very tactful and left plenty of room for himself.

Ollie glared at Scott with disdain, this time for the purser's greasy and sophisticated. She said to Eric in an intriguing tone, "I hope you can give Mr. Scott a happy ending." ”
