Indescribable Hallucination

"Thinking is a human instinct," Charlotte said slowly. "I think there are many suspicious points in the recent murder cases."

"Huh?" Henry raised his voice slightly. He seemed interested in what she had to say.

Charlotte's eyes darted around.

She remembered that last time, Henry had inferred some of the characteristics of the murderer based on information about the three deceased people.

And they had all turned out to be correct.

Henry was very clever.

Maybe if she talked to Henry, he would find some other clues. Wouldn't Quarto's doubts be resolved if he did?

Yes, she had to talk to Henry.

Quarto was also Henry's son, so Henry was obligated to help his son with his doubts.

Although, Henry didn't even know that he had a son.

Charlotte told Henry all of Quarto's doubts and added a sentence at the end. "I heard it from my neighbor, who is a police officer," she said.
