“！！！” Both the lady and the secretary were taken aback.

"Are you sure? Why is it my husband? Madame obviously didn't have any psychological preparation for this, and the expression on her face that was originally asking for guilt collapsed instantly, and she just pounced on Officer Nishimura and grabbed his clothes. Why did something happen to my husband!? Why is it my husband who has an accident!? Tears flowed down her face as she asked.

Qian Yu sighed softly, and Gray Yuan just closed his eyes and shook his head slightly.

"Please calm down," Officer Nishimura simply pulled Madame's fingers off his clothes and walked past her into Madame's Box 7. "Forgive me for taking the plunge, but it's necessary for me to investigate what's in your compartment."

After a search, Officer Nishimura focused on the long, narrow box that he had taken out under the bed that did not look like an ordinary item, and opened it while informing his wife of what he was going to do. "With all due respect, I need to check what's inside—is it?"

Taking what he saw out of the box, Officer Nishimura looked at the thing in his hand with some confusion, and then turned to look at his wife.

In his hands, is a shotgun.

Shotgun, although this thing looks dangerous, it doesn't mean anything, because everyone knows that the murderer used a pistol, and this shotgun obviously has nothing to do with that kind of pistol - the handle of this shotgun is so different from that pistol that even if you secretly saw off part of the barrel, it is impossible to turn it into a pistol.

"Ah," explained Madame busily. "I like clay shooting, that's why I brought this gun!"

"Oh," Officer Nishimura sniffed the muzzle of his gun to his nose before nodding and closing the box after checking for a mezzanine or something. "Madame, you can put this box away - Mr. Secretary, please take me to see your compartment, for we need to inspect your compartment as well."

The secretary's box was on the 10th, and Officer Nishimura didn't have anything suspicious in it - at least he couldn't check anything suspicious, except to find a long bag containing the fishing tackle that the secretary had brought for his boss.

At the same time, there was no anomaly in Keitaro Izumo's cabin. (The original book did not specify the number setting mode of the carriage, but gave the number of the four rooms with Xizi, the jumping carriage, the lady and the wooden sword brother, so I made up the specific number order according to the known conditions, that is, the car number was set according to the odd number of one layer and the even number of the second layer.) At the same time, in order for Keitaro Izumo and his wife to live next door, I swapped the rooms of Keitaro Izumo and the secretary. ）

"I don't know how long it will take to investigate......" Officer Nishimura sighed after checking the secretary and boss. If you really have to check one by one, you will definitely end up with endless trouble. ”

However, Chiba has a different view - he believes that there are only three possibilities for the murderer: 1. The murderer is a secretary, 2. The murderer is a wife, and 3. The murderer really jumped out of the car and escaped.

For no other reason, according to Conan, the killer fired a shot when he shot Keitaro Izumo, broke the window pane with three bullets in the car where he jumped, and forced Conan and Dr. Asa back with two more bullets.

The point is that the killer fired only two shots – probably because he only had two bullets left, but the undeniable fact is that two bullets were a little less anyway. Once Conan or Dr. Asasa glance up after two bullets, the murderer's escape is exposed. In fact, according to Conan's account, the murderer was not far away from them, and even an untrained person could easily hit Dr. Asa at this distance, so it can be judged that the other party's purpose was to intimidate rather than shoot, but two bullets actually made it difficult for Conan and Dr. Asa to dare not raise their heads for a long time, let alone enough time for the murderer to flee too far, even if he hid in car 9 not far away, the time it took to open the door of the car might expose himself completely to Conan and them. ，

In other words, if the killer was sure to buy himself enough time with two bullets, he was obviously sure that he would disappear from Conan's view within a second or two, which meant that he either dodged into the jumping car, or he hid in the staircase where cars 8 and 10 were located to avoid Conan's sight.

If you extrapolate according to this line of thought, the possibility that the murderer is a wife is actually not very large, first, her height is not particularly high enough to play the murderer, and second, her cabin is also on the first floor, and if she hides in the carriage, she will make a loud closing sound. (Conan and the others only heard the murderer closing the door of Box 5 in front of them before jumping out of Box 5, and did not hear any other sound of the door closing.) ）

However, it was not impossible for Madame to hide from the world, especially if Qian Yu had seen a means that might be available here.

The Teenage Detectives had previously been to a movie theater and solved a murder case there. In that case, the prisoner used the switch between the two screen windows to make the body of the deceased Zhang Tian Masaji suddenly appear in front of everyone.

If it is said that what Conan first saw was not the murderer standing in front of the No. 5 carriage where the car jumped, but in front of the No. 7 carriage where his wife lived, and the bright light he saw was also the light in the No. 7 carriage. If the killer opened the door of car 5 with the lights on and turned off the lights on car 7 when he shot and suppressed Conan and Dr. Asasa, Conan and Dr. Asasa who had recovered from the suppression might have thought that the prisoner was standing in front of car 5 from the beginning after they rushed to the side of car 5 and witnessed the door of car 5 being closed. And the murderer only needs to close the door of Box 5 and the door of Box 7 at the same time as the door of Box 5 somehow to get out of Conan and Dr. Asasa - for those on the move, the door of Box 5 with the lights on is closed, but it is not so easy to be spotted when the door of Box 7 is also closed in the darkness next to it.

But there is a problem with this method - the doors of Box 5 and Box 7 are so far apart that it is impossible for even an adult man to pull the door of Box 5 when he is hiding in Box 7.

Perhaps, I should check whether there is any connection between the door of box 5 and the axle slide of the door of box 7, so that the murderer can close car 5 at the same time when closing the door of car 7?
