Liam's father left that Saturday morning with a tracker in his coat, planted by his son. A microphone would be harder to explain. Half an hour, Liam changed and left to fallow him. With a blinking dot on his cellphone map marking where his father was, it was easy to find him.
The Mauvais Hotel?
His father, Chief Adams, was talking to co-workers Arther, Ide, Mark (dumb), Moore. A striking figure in trench-coat came into the scene, and they followed her. Liam began another train of thought. "Offbeat... L? But most likely isn't. He wouldn't risk it."
Liam left. There wasn't much to see anymore without risking having to explain himself-not that that would be hard.

"I am a detective." She said.
"What?" Mark drew a blank.
"I'm not the Killa." She turned around to a joint room.
"You're not L, either, are you?" Mark said.
She stopped walking and turned her head, "I Am L."
"S-sorry-you just look different than I imagined."
"Whatever." She said, "By the way, leave your cellphones and things by M. Maria, I think it's okay to show yourself."
Maria took off the mirrored-glasses and hat. Mark whistled.
"That's out of line!" Chief Adams said.
They went into the joint room with L.
"How do we know you're not really the Killa?" Adams said.
"You don't. Am I suppose to prove that I am?" L said.
"It would help us, yes."
"Okay," L sat in a loveseat, daring anyone to sit next to her. She spun around an open laptop with copies of their ID. "You would be dead if I were the Killa."
No one said anything.
"Trust me?" She said.
"I... don't know." Mark said.
"I trust you." Chief Adams said. Arther and Ide agreed. Then Mark did too.
"Good." She said, and turned the laptop back to herself to open a file, then turned it back to them. "The suspects."
They took a moment to take this in.
"L." Adams said.
"I'm listening."
"As a father, I do not like being involved with my son as a suspect."
"How-how can you even suspect Liam?" Mark bursted out.
L did something along the lines of rolling her eyes. "Logic." And she explained why Liam was a suspect.
From a small dish on the coffee table, she took what looked like a cube of sugar, and popped it into her mouth. To the teams' response, she said, "Salt cubes."
