Fengchen didn't care about the shallow dust on the futon, squatted and sat on it, experiencing Liu Yuankai's artistic conception. The pen ~ fun ~ pavilion www.biquge.info glanced left and right, then picked up the drawings on the low table and took a closer look: "Well~, these are all maps." This is a map of the world, this is a map of the country, this is a map of Yangyue City and a detailed map of the distribution of buildings......", he looked up and asked, "How did you find it?"

"Still no clues", the two came to Fengchen, they didn't know what a clue was, how to find it?

"That's right", Fengchen muttered, "Now that you know the content of the entrusted task, tell me what you think."

"I think that Liu Yan is suspicious", at the critical moment, no one was ambiguous, and Zhu Liang spoke first.

"Tell me why"

"My father disappeared, and as a son, he still cared about his work, rather than helping us," Zhu Liang said blandly

"The reason is reasonable, but not sufficient," Fengchen said, "maybe it's really like he said, he is just preparing for 'what if' and supporting his family."

"It's reasonable for fathers to be workaholics, and sons to be workaholics; However, you can't have both fish and bear's paws, and working wholeheartedly will only lead to the loss of family affection, do a father and son who only know work still have family affection to talk about? This may be Liu Yan's motive", Zhu Liang said insistedly

"Well, this proposal needs to be considered", he looked at Meng Ying and asked, "Did you find anything?"

"The elderly generally live in rooms on the lower floors, and it is somewhat unreasonable for the elderly to live on the roof; I just noticed that the kitchen and dining room are on the ground floor," Meng Ying said

Fengchen got up and said, "We don't know about the affairs of this house, so let's ask the young lady outside to come in and ask."

Just do it, and after a while, he brought the maid in.

"Miss Lian, may I ask Mr. Liu who lives on the top floor, isn't it very inconvenient to go up and down the stairs during meal time?" Fengchen asked

"No, because the lord usually stays on this floor, and when the meal arrives, I will bring the food. After the master finishes eating, I will come and bring the cutlery down. The maid replied

"Oh, that's the case", he asked again, "May I ask what is the father-son relationship between Master Liu and Young Master Liu Yan?"

The maid writhed with some embarrassment: "This...... As a servant in this house, I don't have much to say. May I ask Mr. Feng why is this asked? ”

"It's nothing, it's nothing," he said sloppily, pointing to the floor-to-ceiling window: "This floor-to-ceiling window is very big, you can see the panoramic view of Yangyue City."

"Well, because the master doesn't like to go out, he chose the best location in this house and converted it into his current studio."

"Is the blackboard used by Mr. Liu for calculation or construction?"

"Probably, the lord doesn't allow anyone to enter his studio," the maid said uncertainly

"There are so many books on this shelf, all kinds of mystery novels," he said, pointing to the shelves

"Well, as long as there are other mystery novels released, the master will buy them and put them on the bookshelf"

He asked suspiciously, "Isn't it very troublesome to find books like this?"

"No, because the order of the books is arranged by the date of the edition, as long as you write down the date of the edition, it is easy to find. That's what the lord told us," explained the maid

Hearing this arrangement, Fengchen subconsciously glanced at the bookshelf, but unexpectedly, seeing an important clue, he hurriedly ran over: "No, the order of this book is not arranged by date at all."

Meng Ying also looked at the date curiously: "The date is right, there is no wrong arrangement."

"No, take a closer look, these three books," he said, pointing to the two

Meng Ying looked at it, but still didn't understand. At this time, Zhu Liang spoke: "Edgar Allan Poe's The Fall of Usher House was published in September 1839; Agatha Christie's Murder on the Orient Express was released on New Year's Day in 1934; Finally, there is Conan Doyle's "Sherlock Holmes", which was published around the nineties of the eighteenth century.

And the order of these three books is wrong, these are all famous mystery novels, no matter how confused Liu Yuankai is, he will not arrange these books wrong! ”

Zhu Liang turned the computer screen and showed Meng Ying the information he had just searched for on the Internet.

Fengchen nodded and said, "That's right, the authors of these three books are all from different generations, and as a mystery writer, you shouldn't put it in the wrong order." And it doesn't make sense to mix these three books in this pile of books from the 19th and 20th centuries. ”

The maid's face changed slightly: "Strange, books of this era, the master is usually placed in the collection room, how can they appear here?"

"This is probably a hint left by the murderer or Master Liu", Fengchen pulled out "Murder on the Orient Express", there was a layer of things on the side edge of the book, he picked a few times, and then tore hard, and a long note one centimeter wide was torn off, revealing the real handwriting inside - "Forbidden Fruit"

He hurriedly took down the other two, and sure enough, they were the same, with fake titles on the side edges: "Everyone, help find the books with such fake titles on the shelves."

After looking for more than half an hour, I finally finished looking for it, and there are a total of 10 books, which are "South Lying in the North Moon", "Fengshan Room House Incident", "The Most Valuable Time", "My Restrictive Reasoning", "Backward Dozens of Days. Doomsday", "What Can Be Yesterday and Tomorrow", "Backyard", "Forbidden Fruit", "Two Hearts of Myself", "Who Will Be Responsible in the End", each book has a serial number under it, in order of 1~10.

Several people observed the mysteries of these ten books, but they had no clue, and Fengchen quickly calculated in his heart: "If you arrange them according to the first word, it is South, Peak, Most, Me, and Fall...... Oops, no, can't read. In the second word...... Still can't read it. Arrange by the third word...... Still no, "Backyard" doesn't have a third word. The names of these books are different in size, how to solve them? ”

The maid looked at the three of them who were thinking about something, and couldn't help but cover her mouth and smile.

"Did Miss Lian find anything?" The maid's smile was caught in his eyes

The maid stopped smiling and said, "No, I just saw that the three of you were about the same height, and I thought you were very destined, so I couldn't help but laugh, I'm sorry."

"What's so funny about this", he rolled his eyes in his heart, and replied without changing his face: "It's okay, maybe it's because we're all freshmen, so we're just as tall...... Yes! By the way, you can also arrange it like this."

He squatted down, stood up each book, asked Meng Yingtuo to hold the first book, and then arranged them according to the serial number, and then walked to the side to take a look, and the answer was clear at a glance......
