Investigating, from top to bottom

He followed the Old Mobster to the room with the door open, where he saw the Heiress with her two henchmen; the girl was finishing her breakfast, staring blankly.

"I'd like to ask some questions..." started the Illusionist but was promptly interrupted by the Old Mobster.

"You don't need to answer anything for him. Neither he nor the Cowboy have any authority here."

"But didn't she go straight to her room and sleep until dawn? In that case, she has nothing to hide," the Illusionist ventured, hoping to find flaws in each of them.

"That's exactly right. I have nothing more to say," replied the Heiress. She didn't seem cold, but she wasn't fully present in the conversation. She turned, handed her plate to one of the henchmen, and that's when the Illusionist saw it – a Tarot card in the young woman's pocket.

"Excuse me, could I..."

"She's already said everything she had to say! Just look at her, she's traumatized. Leave the girl alone," retorted the Old Mobster, closing the door to the room and separating the Heiress from the Illusionist.

He needed that card. How did the Heiress have it? Did she steal it from the Fortune Teller? Maybe she was the real culprit in the end. But he wouldn't be able to find out now; the Heiress was off-limits, and he didn't want to confront four henchmen at the moment, even if he thought he could win.

So he decided to take a step back, take a moment to breathe while considering what he already knew. After all, there were still things he wanted to investigate.

He went to the front of the train, where he found the Train Conductor. She confirmed that all the train workers were in the last car, sleeping, and they could vouch for each other. Deep down, he knew the problem was among the passengers. He didn't find anything strange in the front cars and moved on to the first storage car.

Among his various belongings were several mirrors of various sizes, covered with cloths, but it was still strange. However, it was just that, strange; he didn't find any clues.

Next, he found himself in the baggage car. Several bags and suitcases were neatly arranged on the sides of the car. He wondered which one belonged to the Fortune Teller, but he didn't feel comfortable snooping through her things. Besides, nobody else on the train would appreciate having their belongings rifled through, and he feared their reaction.

Then he moved on to the second-class cars. The first room was empty, and he once again wondered if there was a reason for it. After all, he didn't have a genuine ticket. Was it meant for someone else, or was it unsold?

Next to it was the Cowboy's room, followed by the Criminal's, and finally, the Fortune Teller's. Next to her room was the second class bathroom, so anyone who needed to relieve themselves would have to go there.

He wanted to see the Cowboy's and the Criminal's rooms, as there might be more clues, but it wasn't the right moment, and he didn't want to irritate the Cowboy.

He continued to the first class cars. Each one had a private bathroom, so they wouldn't have to leave their rooms. The first one belonged to the Noble and the Lady, the second to the Old Mobster, and the third to the Heiress. They had separate rooms, and the henchmen guarded the hallway while they rested in the last first class room, where they presumably took turns for security duty.

He remembered Lady's statement – she had heard footsteps coming from different directions, but since the car was the first in the wagon, everyone who came from above would have come from the second class cars, and anyone returning would also go there. However, that didn't absolve the rest of the first class car, as they could have done things that Lady simply didn't hear.

He made his way to the restaurant, where the body was found. It was no longer there, and he wondered where it was. Perhaps it was discreetly hidden in the storage car, wrapped in cloths, which is why he hadn't found it. Any clues there had already been discovered or covered up by the Cowboy, so he decided to move on to the casino.

It was his first time there; it was similar to the restaurant car but with fewer tables, a bar, and a shelf with various decks of playing cards and game chips. He thought he would have enjoyed it very much under normal circumstances, but he couldn't take advantage of it now. With a quick inspection, he found nothing out of the ordinary.

The last two cars were for staff only, but he asked to enter anyway. The kitchen was very clean, and the Cook was working there. There might be several crime weapons there, but no vampires.

Finally, he saw the staff's room and, once again, confirmed that they were all there throughout the night.

Now he had a better idea of the layout of the place and finished his inspection back in the restaurant car, where lunch was being served. He didn't know how these people could be ready to eat so calmly where a murder had occurred, but he had to focus on the mission.

The only ones he couldn't see were the Heiress and two of the henchmen, who were probably eating in their room. Without asking for permission, he sat down at the table with the Cowboy.

"If one of us is a vampire, why don't you just pass a crucifix over all of us and find out who it is?" the Illusionist asked.

"It's not that easy. There are many myths surrounding vampires, and I don't know how they really work. Do you think garlic will repel them? Not even the sun kills them directly; from what I've found, they just become weaker and tired, but it's not a direct method to find out. Besides, I wouldn't be able to convince everyone to stand on top of the train, soaking up the sun until we see who gives up earlier."

The Illusionist accepted the explanation but had his own theories forming and needed some time to think. He picked up his plate of food and headed towards his room, both to reflect and to distance himself from where the crime had occurred.
