After questioning Hiroo Tsuyo, Mizumatsuki's second search was the maid Koya Ryozo.

Koya Ryozo looked nearly sixty years old, wearing a butler-like deacon suit, and his hair and beard were meticulously groomed, giving people the feeling of an old butler of the British aristocracy in the last century.

At least Mizumatsuki felt that Koya Ryozo and the White Horse Detective who came back from studying in the UK must have a very low sense of disobedience, both of them had a British gentlemanly atmosphere, but the gentlemanly demeanor of the White Horse Detective could not be maintained for too long.

When Mizuma walked into Koya Ryozo's room, Koya Ryozo was making tea calmly, and it was just two teacups, as if he had calculated that Mizuma Moon would come in during this time.

"Poor hospitality. Koya Ryozo pushed a cup of tea forward.

The tea in the water cup can really be called turquoise, and it is a deep green, and there is a piece of tea suspended in the middle, like a small boat.

It's a pity that Mizumayue is not the kind of big family that knows how to etiquette, and she doesn't know what to say, so she just took the teacup and tasted it, although it was not a cow drink, it was a little bad for the scenery.

"Good tea, endless aftertaste. Smacking the taste twice, Mizuma Yue praised.

The police officer praised it falsely, the tea was just bought at random when he came, it was not a good tea, it was just brewed for a while, and there was no way to talk about the aftertaste. "Koya Ryozo doesn't seem to give Mizuma Moon much face, probably an old man with a stubborn personality.

"So I'm talking about good tea, not good tea. Mizumatsuki said very wittily, glad that she had just said one more word.

"So what did Mr. Police Officer come to ask about?" asked Ryozo Koya.

At this time, the alarm bell in Mizumayue's heart rang wildly: When did the initiative of the conversation completely in the hands of the other party? It seems that as soon as you enter the room, it will be like this, right?

"Ahem...... First of all, I would like to ask Mr. Koya, you don't have a proof of abnormality, do you?" asked Mizuma as seriously as possible.

"Yes, I had been preparing dinner in the kitchen before dinner, and before I found out that the deceased had died, I went to his room to call him for dinner, and after calling for a long time without agreeing, we went outside to check on the situation. Koya Ryozo sat down and explained.

"The deceased's room was locked at that time, right?" Although he had already heard Hattori Heiji mention it once, Mizuma Moon confirmed it again.

"Yes, I've tried to open the door. Kotani nodded.

"Didn't anyone knock on the door?" Mizuma Yue felt a little incredible, shouldn't the normal process be to organize people to bang on the door without anyone answering? At least that's right, the secret room cases that he took over from the detective are like this.

"Because of the previous secret room exam questions, and the deceased once said that he wanted to recreate the secret room, everyone thought that the deceased had arranged the secret room at that time, but they didn't expect that he was really killed. Kotani explained expressionlessly.

"Shouldn't the answers to the exam questions be submitted in an envelope?" asked Mizumatsuki in surprise, no one had ever mentioned it.

"That's right, but that man is hell-bent on showing himself, and Mr. Tail and I can't stop him. "Koya Ryozo unceremoniously defines the deceased as a manifestation of himself.

"In that case...... Huh?" Mizuma seized the clue and immediately picked up the walkie-talkie and turned the frequency to Shiratori.

"Shiratori, go and see if the windows at the scene can be removed in their entirety, I mean along with the window frames. Mizuma Yue instructed that if the deceased was cracking the method set up by Hiroo Ao, maybe the secret room at the scene was the method used by Hiroo Ao.

"Moriya, is it okay to move the corpse?" Shiratori's voice came, and Mizuma remembered that the corpse was leaning against the window.

"I guess I can't remove it, the screws are all screwed on the window frame, and I can't push it. Shiratori tried lightly, but didn't push.

"Try it with some force, probably with carpentry glue. Mizuma continued.

"Okay...... Well...... I really took it down, and there was only a little bit of these screws!" Shiratori pushed hard, and really pushed the window frame down, if it weren't for his quick eyes, he would have fallen directly.

"Look at the tools in that carpentry box, scissors, glue or something, and whether there are any screw tails. Mizuma continued.

After a while, Shiratori's voice came again: "The screw tail was not found, and the glue did not decrease, but the pliers ......"

"What's wrong with the scissors?"

"The tools are all new, but you can still find some marks on the scissors, but I can't be sure if they were left by the screws. "Shiratori knows the wind of Mizuma Moon very well, and everything is uncertain.

"Well, is there anything else?" Mizuma felt as if Shiratori still had something to say.

"I'd like to check one more of the other toolboxes, and I feel like there's something missing in them. Shiratori said with some hesitation.

"Then you can go to the tail room and take a look. Mizumatsuki said, just too lazy to go back to see if there was anything strange in Hiroshi's toolbox.

"Hi, I went ahead and checked the scene. Shiratori finished speaking and closed the intercom.

Putting down the intercom, Mizumatsuki glanced at Koya Ryozo, and sure enough, his expression did not change by half a minute, and he couldn't help but sigh at the experience of the old man and the depth of the city.

"There's another question, how do you see Hiroo Tsuneo specifically appointing you to be a maid here under the instructions of others?Or do you know?" Mizuma continued to ask, this is the biggest doubt about Koya Ryozo's identity.

"I know, Mr. Tsuneo said it directly, and at the time I thought it was strange and unsettling. After a moment of silence, Ryozo Koya said.

"Then why did you still accept the hir?" Mizuma asked strangely, it is human nature to seek good fortune and avoid evil.

"Because in order to hire my old bone, Mr. Aowei raised the commission to the extent that I could not refuse, and after losing my old job, I will not tell you that my life is very poor. Ryozo Koya said with a wry smile, "So at that time, I convinced myself with the idea that maybe some acquaintance wanted to help me and wanted to take care of my self-esteem that made the form so weird." “

"What about you now, do you feel anything strange?" Mizuma asked with a little curiosity.

"Hmm...... Anyway, there is indeed a little, but maybe the person who arranged this show is really an old acquaintance of mine. Koya Lian said while thinking about it, and the corners of his mouth actually revealed a little smile.

"Do you know who the murderer is?" Shui Jianyue was a little surprised, but secretly reminded herself in her heart not to be induced by this person, after all, the person in front of her was indeed a suspect in the case.

"All I can tell the officer is that the layout here is very similar to the place where I used to be on an errand, and as for more things, I can't just give them away. Koya said with a smile.
