"Did you find anything?" Upon returning to Monica's crime scene, Chiko saw Eric circling the scene without saying anything.

"Tell me what you think. Instead, Eric began to question Chiko.

"Me?" Chiko was surprised to believe when this conceited rogue detective would be willing to listen to her.

"Is there a problem? Could it be that you CIA female agents are only going to be rough with men and not use your brains. Eric smiled brightly at Chiko.

Chiko rolled her eyes, it turned out that Eric was still the same Eric, hippie smiling, not serious. She said angrily: "Female agents in the CIA will only be rough with rogue villains, just like a third-rate detective like you." ”

"Well, then prove that a female CIA agent can see more than a third-rate detective like me. Eric said defiantly with Xiang Chiko.

"I'm just concerned about the other red heel, and if that's the key clue to find Shock. Chiko came up with her own idea.

"Tell me your reasoning. Eric asked.

"Isn't it obvious that Monica is barefoot, and there is only one heel on the scene, and the other heel may be hiding an important clue. Chiko felt that she had seen farther than Eric.

"Do you know Agatha Christie's ABC Murders?"

"What does this have to do with a detective novel? It is about a murderer who kills people in the alphabetical order of a railroad guide, and puts a railroad guide next to the body of each victim, creating the illusion that this is a serial murder, but the real goal is only one. What does this have to do with Monica's death, now only Monica is the victim, there is no serial killing. "Chiko couldn't understand Eric's intentions.

"You need to look a little bit deeper. Eric gave a wicked smile.

"Then tell me what profound things can be seen in a detective novel used to pass the time. Chiko asked unconvinced.

"I remember when we first met Monica, she was on a pair of high heels. For a woman like her, one less heel can really whet the appetite of the average person. We would ask where the heels were, why there was one missing heel, and whether that shoe was hiding any important clues. Eric's words were filled with the ridicule of Chiko as an ordinary person.

"Is there a problem!" Chiko naturally heard the bad intentions of this third-rate detective.

The problem is the real approach of ABC Murder, where Detective Poirot initially focuses too much on the ABC railroad guide next to the bodies of each victim in a serial murder case and ignores what the murderer's real motives are. Like the case in front of us, the red heels that disappeared are the railroad guide in "ABC Murders." Eric points out the key.

"You mean, those red heels are a trick that Shook set up for me?"

"Half right and half wrong. Eric's reply disappointed Chiko.

"So, where is right, where is wrong. Chiko pursed her lips slightly.

"Yes, yes, the murderer did use a trick. The mistake is that now in addition to abducting Leonardo, what other evidence points to that it was Shook who killed Monica. Eric was provoked by Qianzi's sudden cuteness, and his heart was pounded.

"This ...... This ......" Chiko was suddenly speechless when asked by Eric.

"Anyone can be a murderer without sufficient evidence. Eric smiled mysteriously.

"Then you have found something I didn't find. Chiko apparently threw in the towel.

"Every murderer has a motive for killing, and in the same way every victim has a motive. Eric looked at the left and right ends of the hallway, "So Monica's motive is what she's here for." ”

"What is the victim's motive for?, what is Monica doing here?" Chiko seemed to notice something, and there was nothing else on Monica's hand except for that deadly high heel, "Maybe Mrs. Hudson asked her to come here for something?"

"Ask Thatch and look at the castle's surveillance footage and her communications. ”

Chiko followed Eric's words and dialed Mrs. Hudson's study. Thatch didn't let prejudice deter them, and he was quick to come up with a no-no. There is no associated monitoring, no call logs.

"Well, the question now is clear, why did Monica come? If it is a passerby, then it is impossible for a housekeeper who has served in the castle for more than ten years not to know that this road is not the most recent one. Eric explained.

"Maybe Schock tricked Monica into getting here and then sneaked up on her from behind. Chiko came up with another hypothesis.

"The place where Monica died is on your side, how did Shook make Monica quietly take off her high heels and knock her head off so that she could escape without any blood, considering that Thatch was also present at the time, and it was not easy to hide from his eyes. Eric vetoed Chiko's hypothesis without any suspense.

"That'...... That...... How did the murderer do it?" Chiko was speechless when asked.

"Have you ever noticed Monica's hand holding her heels. Eric adjusted Chiko's focus.

Chiko followed Eric's instructions and carefully observed Monica's hand. Monica was holding the red heels upside down, seemingly tightly, her four fingers already firmly wrapped around the heels, and there was even a wound between her index finger and thumb that had been worn out by the brim. Seeing these details, Chiko began to realize that if Monica was killed, the murderer would never have held her shoes so tightly, let alone caused such a worn wound.

"This ......," Chiko looked at Eric in confusion.

"Quite simply, Monica's killer is Monica herself. Eric summed it up very succinctly.

"Kill yourself?" Although Chiko had already guessed the truth of these wounds, he still couldn't imagine it.

"I think Monica and Shawk, and the murderer who attacked Mrs. Hudson, are all in the same group. Eric threw out a more direct truth.

"Elik, you know, Monica and Shawk were both servants who had followed Mrs. Hudson for more than ten years, and their father, grandfather, and grandfather had spent their lives serving Mrs. Hudson's family. Chiko emphasized.

"You're saying they're loyal?" Eric sneered, a sneer that made Chiko blur the sight of Eric in front of him.

"But loyalty doesn't mean anything!"
