Why had Sheldon felt the need to do that? Tilda started to say something but stopped, remembering the dead mouse.

"Where is it?" Lyndon asked directly.

Elma pointed towards the door. "I put it in the garbage bag."

Lyndon followed her pointed finger to the black garbage bag, knelt down, and carefully untied it.

Inside, he found a shoebox. When he opened it, he saw a bloody, crushed mouse.

The body was so mangled it made everyone queasy.

Lyndon frowned and closed the shoebox.

“Did you contact the authorities?" he asked.

“No, we haven't," Elma replied.

Lyndon stood up, looking for a wet tissue.

“You should wash your hands first," Tilda suggested from nearby.

Lyndon nodded and headed to the bathroom.

As he passed Tilda, he asked, "Do you have a camera at your door? Did you see who left the parcel?"

Tilda nodded. "Yes. It was a little boy; he should be about six or seven years old."

Lyndon, surprised, continued towards the bathroom. "A little boy? Do you know who he is?"

"No, I don't," Tilda replied, following him.

When they reached the bathroom, Tilda opened the door for him and turned on the faucet.

They moved in sync.

Lyndon glanced at her as he washed his hands. “Did someone write something on your door?"

Tilda's face went pale again as she remembered the word "DIE" painted in red.
