Between your cases in Sherlock Holmes Chapter One, you will find dozens of delightful side-cases to keep you sharp and help you earn a couple of bucks on the side, too. You’ll find the great Blindsided case inside the Cordona Chronicle building by eavesdropping on two men. To start this investigation:

  • Pin the clue Eyes Wide Shot.
  • Head to the Old Ruins in Southwestern Grand Saray.
  • Move toward the ruins on the beach to find the Undertaker.

You’ll automatically enter a conversation with the Undertaker when you get close enough—exhaust your dialogue options with him and move up to the crime scene by the ruins.

You’ll find that the police have left four evidence markers in the area, with each spot offering a few clues. Start with the dead body in a yellow vest and you’ll find:

  • A gun above his head.
  • A key to the left of him.
  • A bullet wound to the chest.
  • He’s blindfolded.

Continue along with the markers and investigate the easily spotted clues. When you come across a yellow jacket, interact with it and you will have access to it in your wardrobe for later.

At marker four, you’ll find a book that contains the three rules for Duelling Club. Jon will challenge you to adhere to the rules of the club for the remainder of the investigation, doing so will net you a bonus later on.

Pin the clue Duellist’s Footprints and look up the eastern hill. There’s a spot up there containing more evidence—head up and find a few more clues to begin piecing together the scene. After you’ve found all of the evidence, a node will appear near the body. Interact with it and arrange the scene as follows:

  • Marker One: Man falling backwards, gun in air.
  • Marker Two: Man standing and firing toward hill.
  • Between markers two and four: Two Duellists taking guns from man with top hat.
  • Marker Three: Man with top hat standing and holding gun, dropping case.
  • Up the hill: Man with top hat on one knee, firing down.

  • Marker Three: Man with top hat holding ears, dropping case.
  • Up the hill: Unknown figure shooting down the hill.
