Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 61 Bloodstained Bathroom

In the bathroom of the apartment of Hideo Furukawa, the sales manager of a large trading company, the body of Miki Tsubouchi, the mistress of Hideo, was found.The first person to discover was Hideo Furukawa's wife Ryoko.She said it was due to her mother's illness, and she was scheduled to stay at her natal home for a week, but because her mother's illness was better than expected, she returned home two days early.

Unfortunately, Yingnan was not at home when he went out, and there were no special changes at home.Two hours later, intending to take a shower, she turned the bathroom doorknob, but the door was locked from the inside.Feeling strange, she looked in through the glass and saw someone lying on the ground, so she hurriedly called the police.

There was a fruit knife stuck in Miki's chest, and she was holding the handle tightly with both hands, but there was no other trauma.The bathroom was a complete backroom, apparently suicide.However, the criminal police were suspicious of the scene. Why?
[Answer] When attempting suicide with a knife, it is easy to leave a minor injury called "hesitating injury".This is due to the psychology that people cannot act resolutely.Miki had no trauma other than the fatal chest stabbing, so it's hard to call it a suicide.

In addition, it is not natural for Miki to die with a dagger in her hand.Probably after being stabbed, he subconsciously grabbed the dagger and pulled it out.Furthermore, it is also wonderful to commit suicide in the bathroom of the lover's house, usually on the bed.What is even more incredible is that Ryoko said that she found the testimony two hours after returning home.If what she said was true, the soap suds in the bathtub would have been gone by now.

In summary, the following reasoning holds.Yingnan, who brought his mistress home while Ryoko was not at home, went out for something urgent.Not long after, Ryoko came home suddenly.As soon as he entered the room, he happened to bump into Mei Shu who came out of the bathroom wearing only a bath cloth.Knowing that this person is her husband's lover, Ryoko couldn't help being furious. In a fit of anger, she grabbed the fruit knife in the kitchen and aimed it at Mei Shu's chest.

The frightened Miki fled into the bathroom with a fruit knife stuck in her chest, locked the door from the inside, and tried her best to pull out the fruit knife, but died before she could pull it out.
