Zhang Heng didn't know where Holmes had gone, but he found some maids who had a good relationship with the previous three victims, and restored the activities of the three victims from them.

Zhang Heng finally locked his eyes on a man named Mark Cohen.

He was a Jewish physician active in the Whitechapel generation, but he was not a qualified doctor registered with the Central Medical Council, and of course there were very few qualified doctors who did serve the maids.

Not to mention those pampered physicians, internists have always been the first level of the three ranks, claiming to be a gentleman, but with the rise of surgeons and pharmacists, internists are constantly losing leadership, especially when pharmacists gradually transform into general practitioners, and are working with surgeons to actively promote the reform of the British medical system and fight for more rights...... However, even if it is a general practitioner, there are not many in the Eastern End, let alone serve the lowest level of servants.

It is precisely because of this that there is a living soil for people like Mark Cohen.

In a sense, he is a bit similar to the role of a general practitioner, basically seeing all diseases, and is also responsible for midwifery and some gynecological diseases, which is why Zhang Heng will focus his attention on him.

The maids' evaluation of him is more complicated, on the one hand, his fee is very low, although it is not a miracle doctor, but it can still play some role, but there are also many maids who say that they will feel very uncomfortable when they are with him, especially his eyes, when his gaze falls on you, it is like being targeted by a snake.

Zhang Heng inquired about Mark Cohen's residence and rushed there before sunset.

The smell here is not too good, there is a pigsty not far away, there is chicken manure everywhere on the road, women are washing clothes by the sewage, and several men with smoky faces who are supposed to be boilermakers in a nearby factory are coming from a distance.

It didn't take much time for Zhang Heng to find the apartment of the female doctor, but when he knocked on the door, there was no answer inside.

Zhang Heng glanced at the lock on the door and found that it was only the most rudimentary kind, which basically could only prevent gentlemen, so Zhang Heng glanced around again, and saw that no one noticed this, so he quietly picked the door lock with the knife he carried.

The smell inside the door was worse than outside the door, it was a special smell mixed with the smell of sweat and rot, Zhang Heng frowned, and pulled out the revolver on his waist.

As a result, he saw a pool of blood on the ground after walking two steps, there was almost no furniture in the apartment, only a bed, a wardrobe, and a dining table, socks and dirty clothes were thrown everywhere, Zhang Heng walked to a cloth curtain along the bloodstains, and a pair of boots could be seen through the gap under the curtain.

Zhang Heng didn't open the curtain, but directly stabbed it with the knife in his right hand, and the blade easily tore the fabric, but it fell empty behind the curtain.

A false alarm? The boot was still on the ground, so it seemed that it had only been placed here by its owner.

Zhang Heng quickly opened the curtain with his other hand and saw a place similar to a simple consultation room, with two stools and a small workbench, the most eye-catching of which was undoubtedly a bloody organ on the workbench.

This is where the blood and the stench on the ground come from, and a swarm of flies are feasting on it at the moment.

Zhang Heng's first reaction was to find the part of Bernice's uterus and abdominal flesh that was lost in the third homicide, so that he would lock the murderer, but the next moment when he walked to the table to take a closer look, he found that the things on it did not look like a human womb in terms of shape and size, but more like some kind of animal.

Zhang Heng thought of the pigsty he had seen on the side of the road before.

In addition, he also saw a notebook on the table, Zhang Heng opened the notebook, turned two pages, and found that the things recorded on it were fragmentary, most of them were some trivial matters in life, and there were also some medical research, but when he turned to the back, the content changed, and it could be seen that the person who wrote the things became more and more impatient.

Not only did the handwriting become more and more sloppy, but the content also began to change, more to do with the girls, who complained that he made less money, that the girls always pretended to be pitiful to him, and from his notes, he seemed to have had a conflict with two girls a month ago, one of whom took his pocket watch while he was seeing a doctor, and Mark Cohen chased him out, and was tripped on the ground by another girl, and lost a tooth.

Zhang Heng was about to continue reading, but at this time there was a sound of opening the door behind him, Zhang Heng stuffed the note into his arms, and the person who came also opened the door, listening to the footsteps, it seemed that there was not just one person, but two.

This surprised Zhang Heng a little, but it did not affect his plan.

Zhang Heng can jump out of the window and walk away now, but when he used a knife to cut through the curtain, this path was actually ruled out by him, because once Mark Cohen found out that his residence had been moved, he would definitely run away as soon as possible, not to mention that Zhang Heng even took his notes.

Therefore, Zhang Heng simply chose to catch the target directly here, and then send it to the police station.

He hid behind the curtain, listened to the footsteps approaching, and at the same time calculated in his heart, waiting for one of them to reach out and lift the curtain, his knife was also handed out, Zhang Heng could see the surprise on the target's face and the horror in his eyes, but fortunately, Zhang Heng stopped his hand at the last moment.

Another policeman also drew the pistol on his waist at the first time.

Zhang Heng raised his hand and threw away the weapon in his hand, indicating that he had no malicious intent.

…………

An hour later, Sherlock Holmes also came to the police station, he knocked on the floor with his cane, and looked at Zhang Heng behind the iron fence with interest, "They were going to let you out half an hour ago, but I asked them to lock you up for a while, so that you can also experience how I felt before." ”

"Did you tell the police to arrest Mark Cohen?" Zhang Heng asked.

"That's right, in fact, before you went to the doctor's house, he was already caught by the police, and those two police officers went to collect evidence." Sherlock Holmes laughed, "It seems that I won the bet this time, and I can finally think about what I want to see in the opera." ”

"I don't think so," Zhang Heng looked at Holmes and said leisurely, "You caught the wrong person." ”

"Caught the wrong person?" Holmes raised an eyebrow.

"You haven't interrogated Mark Cohen yet."

"Yes, but I heard Lestrade say that as soon as he was brought down by the police, he admitted that he was the murderer."

"It's useless for him to admit it," Zhang Heng took out the notebook from his arms and shook it, "If you interrogate him, you will know that he is insane." ”
