Just then, the old-lady detective suddenly smiled.
"I've figured it out."
"In truth, Tycoon No. 1 was killed long ago."
"As for the killer, after setting up the trap, he had already left."
"He went out for a late-night snack, then to a gathering, blending into the crowd and muddying the waters."
"Early the next morning, all the killer had to do was take advantage of the administrator not paying attention, or set up a timed switch, and knock over the disguised bookshelf."
"That let the administrator discover the body."
"The administrator would naturally assume the body had appeared after he locked the door."
"And since the key was in his own hands, and he was the one who opened the door, he naturally couldn't understand why the body had appeared inside a locked room."
"This was a locked room in terms of time. By confusing the time of the crime, it created a physical locked room."
"In that case, the number of people truly suspected of committing the crime immediately expanded," the middle-aged man said, suddenly enlightened.
"Yes, the suspects are still those three people."
After the old-lady detective directly laid bare the trick, the three suspects—two men and one woman—did not immediately refute it.
They only said, "We didn't kill him. Anyone could use a method like that."
However, Wenren Sheng noticed that all three of them had somewhat abnormal expressions.
Clearly, the killer was most likely connected to them.
Perhaps they had hired someone to kill him.
He turned to look at the detectives. He wanted to know what cheats these people had.
That way, he could infer the Demon's level of strength, and then decide what methods to use against them.
The detectives all frowned at once. They could also sense that those three were lying.
