  • Neck - Dog Tattoo
  • Left Hand - Electrical Burn
  • Black substance on pants - Sticky Liquorice
  • Foot - Pungent Mud
  • Right Hand - "Rasco" Tattoo

Afterwards, notice the hammer underneath him, the solvent and cloth drenched in solvent in the crate, and the mud on the floor to the left of the hammer. Walk around to the street light side of the carriage and examine the side of it to see something was painted over, then use Sherlock Talent (cn_RB) to notice there is some text. Look back inside the carriage and grab the Solvent, then head back over and use the Solvent to wipe away the fresh paint and reveal "Underground Electric Railways Company of London", then click it to continue. Next run over to the man in the front of the carriage and examine him:

Head over to the left side of the carriage and use Sherlock Talent to notice something under the carriage by the sewer lid. Click to find a wire and follow it into the nearby building. Head upstairs and to the right to the 2nd door down. You'll need to pick the lock to get inside and you'll be given some new locks to use at that, though you can simply use Lockpick #3/4 twice to get inside easily.

Once inside walk over to the device on the table and examine it. Flip up levers 1 and 3 then use the upper lever. Then flip down lever 1, and flip up levers 2, 3, and 4, then use the upper lever again. Head over and take the document: Smoke on the water, then look out the window.

Head back outside and speak with the police. You'll have to locate five men that could be potential suspects, use Sherlock Talent to "scan" them:

  • The man accused by the police
  • The two carriage drivers standing by the mechanism in the center
  • The man leaning against the building behind the above two men
  • The man standing near the building with the electrical device

You will then open the Map of the Accident with cn_LT and choose all 3 of the men who are NOT carriage drivers as "Suspect", and the two drivers as "Not a Suspect". Use the picture below for reference.


Report your findings to the police.

You will now be tasked with finding out where the carriage that was electrocuted came from, so head over to the carriage but go further down the street. Activate Sherlock Talent and you will notice mud on the sidewalk, a collision with the barrels, and paint on the pole nearby. Enter this shop and notice more mud on the ground, then pick up the document: Snake Nests and Conspiracy from the desk. Try to enter the backroom and you'll have to pick the lock, use Lockpick 2/4 on the inside lock and Lockpick 2 on the outside. Next use Lockpick 3/4 on the inside lock and Lockpick 3 on the outside to enter the room.

Examine more mud on the ground, them use Sherlock Talent to notice the carpet was moved. Move the carpet aside to find a secret passage leading to the Sewers. Head down into them.

Head right and follow the tunnel (there is only one path you can take as everything else leads to a dead end), you'll find a forked path, go left and cross the bridge, then continue left. Take a right further ahead into another tunnel, then go left and up the steps to examine a blue machine. This machine (and another one nearby) controls the water in the sewer, you'll be using it to solve a puzzle so do the following:

  • Set the water level to 0
  • Turn the wheel on the right to open the door
  • Climb down the ladder
  • Push the crate/barrels straight forward (away from the ladder) as far as it will go
  • Climb back up the ladder
  • Set the water level to 1/2
  • Jump across to the other side using the crate/barrels as a platform
  • Click on the pipe in the center to balance walk across it, you'll have to do the usual and keep the Left and Right Sticks inside their circles
  • Use the new blue mechanism to set the water to 0
  • Use the lever to the right to move the ladder to the far left
  • Climb down the ladder (near the lever)
  • Push the crate straight forward (towards the ladder you just moved left)
  • Climb back up the ladder you climbed down
  • Set the water level to 1/2
  • Use the lever on the left to lower the bridge (no need to balance anymore)
  • Cross the bridge to the other side

Fast travel to Scotland Yard.

A cutscene will occur telling you one of the three men escaped to the hospital. By now you should know the layout of the Yard so head over to the Evidence Room. Examine the right side drawer first and look at the Book, then look at the bookmark in the book and the page it leads to, the wires, and the bank note. Examine the center drawer and look at the photograph, gloves, whiskey, cigarettes, and the letter from his Pastor. Examine the left side drawer and look at the box of candy, the two documents: letter from UERL, and letter from hospital, the pen, and the handkerchief with the initials M.B.

You now have everything you need, so press cn_Y and enter Deduction Mode, as usual you will be combining clues to make deduction bubbles, then pressing cn_RB to combine more clues:

  • Mr. Garrett's Side Job + Electrocution = Insufficient Knowledge
  • Mr. Fowler's Work + Electrocution = Not a Specialist

  • Big Bubble appears = Fowler's New Life
  • Electrician + Bank Robbery = Underground Worker
  • Big Bubble appears = Hopelessness
