New Evidence

　　"Emma, you're right.

　　The killer left through here," Benjamin said.

　　"We'd better take a photo of it."

　　"Okay," Emma took out her phone and took a picture of the shoe print.

　　Benjamin leaned out of the window and looked around.

　　There were no pipes or anything climbable near the window, so it was impossible for the killer to have gone down to the first floor from here.

　　The only suspicious place was the balcony two meters away.

　　Since it was the sixth floor, the owners of room 601 and room 602 did not install burglar bars on their balconies and windows.

　　At this moment, the window of the opposite balcony facing this place was open, which increased the suspicion.

　　It was very likely that the killer jumped to the opposite balcony and then left the crime scene through room 602.

　　Benjamin stared at the opposite balcony and said, "If the killer really left through here, then their agility must be very nimble, like a circus performer, in order to easily reach the opposite side."

　　"Emma glanced at the distance between the window and the balcony opposite, and casually said, 'This is not difficult at all, I can do it.

　　If you don't believe me, I can demonstrate it for you.' 'I know you can do it, but not every killer is a special forces soldier like you,' Benjamin said.

　　'By the way, it seems that the police did not get a statement from the owner of Room 602.' Emma replied, 'The police have already investigated the owner of Room 602, they couldn't possibly know anything.' 'Why?' 'The owner of Room 602 is a young couple who have already moved abroad.

　　They have entrusted a real estate agency to sell the house, which means that no one has lived there for at least two months.' 'That's also why the killer escaped to Room 602 without alerting anyone.

　　There's simply no one there, so he could easily leave,' Benjamin said.

　　Emma nodded, then she saw Benjamin walk to the wardrobe, step inside with his foot, and then step out.

　　'What are you doing?' Benjamin walked out of the wardrobe and stared at the spot where he had just stood, saying, 'You see, my footprints are not left behind.' There were indeed no footprints of Benjamin in the wardrobe.

　　Emma frowned and said, 'What's going on? Why are there only William's footprints?' Benjamin replied, 'Don't forget that Sophia is a little obsessive about cleanliness.

　　She always keeps the room very clean, so it's very difficult to leave footprints here.' 'But why did William's footprints remain?' Emma asked.

　　'Don't forget that William always wears the same pair of sneakers, and I checked his shoes, they're very dirty.

　　Therefore, he is more likely to leave footprints here than an average person,' Benjamin explained.

　　'So, besides William, the real killer did indeed hide in the wardrobe, but his footprints were not left behind.

　　Wait a minute!' Emma suddenly shook her head, turned and stared at the window sill.

　　'If the killer couldn't leave footprints in the wardrobe, then why are there footprints on the window sill?' 'It's simple.' Benjamin walked to the window and ran his finger over the sill, immediately collecting a thick layer of dust.

　　'There is dust on the window sill, but the wardrobe is spotless.

　　That's why the killer didn't leave footprints in the wardrobe, but left footprints on the window sill.' 'I see.' Emma finally understood, it was all because of the dust.

　　Seeing that Emma had completely grasped the situation, Benjamin said, 'Let's go.

　　We should go to the opposite side, there may be more clues there.' 'Okay.' Emma followed him.

　　They closed the windows, left Room 601, and restored the seal on the door.

　　Then, Emma opened the door of Room 602 and entered with Benjamin.

　　The layout of Room 602 was exactly the same as Room 601, but the furniture inside had already been removed, making it feel empty."

　　Since the window was open, there was a thick layer of dust on the floor, and a clear set of footprints left on the floor, leading from the balcony to the door.

　　"It seems we were right, the killer left from here, and the footprints on the floor are his." Benjamin stared at the footprints on the floor, it was the best evidence, and it matched the footprints on the window sill of Room 601 completely.

　　"We should take photos of these footprints for documentation." "Okay." Emma took out her phone to take photos of the footprints on the floor, and said, "The steps of the footprints are large, indicating that he was very anxious, and didn't even think about cleaning up these footprints." Benjamin and Emma thoroughly searched the entire house, but besides the clear footprints on the floor, the killer didn't leave any valuable clues.

　　It can be seen that he didn't stay here for long, he jumped onto the balcony from the opposite side, briefly observed the situation inside the room, and immediately opened the door to leave upon discovering it was an empty room.

　　"We should notify the police," Emma said.

　　Benjamin shook his head and said, "The police will say these footprints were left by a thief, it would be best if we can find concrete evidence to prove the identity of the killer, otherwise it's better not to tell the police anything." "Alright." Emma looked through the window and saw Aunt Ava walking towards Building 5, "She's back, should we go down?" "Hmm." Benjamin nodded.

　　Just as they were about to leave, Emma stopped and turned towards the direction of the bedroom.

　　The killer's footprints hadn't been there, her sudden action felt a bit strange.

　　"Did you find something?" Benjamin asked.

　　"There seems to be something here." Emma squatted down in front of the door, there was a small gap between the door frame and the wall, she took off her hairpin, and hooked it inside.

　　A gold ring rolled out from it.

　　"Look, I said there was something shining, turns out it was this!" Benjamin stood in the position where Emma was before and took a glance, if it wasn't for the sunlight suddenly shining on the gap, and Emma's previous position coincidentally formed a diagonal line with this spot, she wouldn't have been able to see the reflection of the ring inside the gap.

　　Benjamin took the ring and looked at it, there was some dust on it, he lightly wiped it off with his hand, revealing that the ring was very new.

　　Although Benjamin had never seen this ring before, he immediately associated it with the mark left on the fingers of the deceased, they were a perfect match.

　　"It might belong to the deceased, it must have been dropped here by the killer when he left." Emma looked at the distance between the footprints left by the killer and this spot, and sighed, "It's a distance of about five or six meters, I didn't expect the ring to roll into this gap." "Give me a tissue." Benjamin took a tissue from Emma, wrapped the ring and put it in his pocket.

　　"Let's go." Benjamin and Emma were going downstairs, and they happened to run into Aunt Ava walking in.

　　Ava Auntie was almost knocked down to the ground and angrily shouted, "Watch where you're walking!" "Ava Auntie, we have some questions to ask you," Benjamin said.

　　"It's you!" Ava Auntie finally saw Benjamin and Emma's appearance clearly, turned around and wanted to leave, still shouting, "I don't know anything, there's nothing I want to say to you police." Benjamin stepped in front of Ava Auntie, smiling, and said, "Ava Auntie, I think there might be a misunderstanding, I'm not a police officer." "You're not a police officer?" Ava Auntie looked at the two of them in surprise, but she didn't fully believe Benjamin's words.

　　After all, the person she was with last time was clearly a police officer.

　　"Is being with a police officer always being a police officer?" Benjamin countered, "In fact, I'm a writer, being with the police is just seeking inspiration for my work."
