Henry Lambton.

Lynch disappeared under mysterious circumstances,
John was exhausted in his search for a friend.
After two weeks of searching, Lambton showed up at Lynch's house with a couple of bodyguards. Henry asked the brown-haired man where his friend had gone.
"So you're saying he just disappeared?" Ljmbton thoughtfully runs his hand over his desk, dusting it with his fingers.
Two bodyguards stand at the bedroom door, and a battered John sits on Yegor's bed, applying a damp towel to his broken nose. Throwing punches in front of two muscular and well-trained men is clearly a bad idea.
"Couldn't he just run away?" one of the bodyguards opines, to which John immediately bristles.
"Lynch would never do something like that," he hisses, and Lambton raises an eyebrow. Hasn't life taught him anything? "He wouldn't abandon his family."
"Mr. Lynch isn't one to run from problems," Lambton says, stepping out into the hallway where things are scattered and "659" is written in red paint on the walls.
Alex, you're with me, Fred, stay with our friend, but please don't use force, we don't need him alive for now.
"Hey, what do you mean bye?" John jumps out of bed as he is thrown back.

• This means if you try to move, you'll get a bullet.
  Henry moves on to the basement.
  "You can't go there!" the brown-haired man jumps up and blocks the way.
  "Do you want to find your friend?" Lambton asks.
  —The door is closed, which means he’s not there!
  Fred twists the writer, opening the door they go inside, Lambton is surprised to see a portal, but now is not the time for that.
  Turning his gaze to the writer, he begins to examine all the mess that was there.
  Having discovered blood and a video camera, they move away from John with Alex and look at the recordings.
