Mystery Detective Adventure Walkthrough Case 3

Task 1 – Talk to the mine manager

• Talk with the lady for some initial information or context to help comprehend the situation. At a later stage during investigations, collect the pass, newspaper, and paperclip from the table for any needed items.
• Click on the fire-shield button to find out whether it has any clues about hidden compartments that can assist in solving this mystery.
• Search through Henry’s death site meticulously to gather all evidence possible and understand what happened, thus leading to his death.

Task 2 – Explore the site of Henry’s death

Before he was killed, the deceased had a gun. Who did he shoot at if he was trapped under the rocks? At the crime scene, there was a palm print smeared with coal. Serial killers usually leave such signatures. Afraid there will be others like them. It explains why something happens and gives an idea of who could have done it.

• Use your paperclip to unlock any locks, then pick up your hammer and spoon parts from your inventory, as you may need them later during investigations.
• When clicking on the fire hydrant, inspect if anything that works or not is hidden there to provide you with essential clues necessary for solving this case.
• You can take a hose pipe from the hydrant or nearby area to siphon water or connect it to another source when needed later.
• Put your spoon part onto the checkpoint window to see if it does something strange, which can also be considered a mechanism for finding other tips.
• Go slowly towards the mine shaft, ensuring you check for any dangers and more evidence around the entrance. Push the gate button then open it because sometimes one may need a pass ready after losing their password keys, etcetera
• Use passes to enter restricted areas within the mining site. Go down and speak with a man to get more information, learn key objects, or even progress in gameplay.
• Take the dirt part from the train. This part can be required to fix machines or use them later. Get the part with a fork from the bottom, as it may be necessary in any future puzzle.
• Use a hammer so that you can break things or repair them to move deeper into the investigation.
• Open shields two times for them to reveal hidden parts or mechanisms that are useful in solving this particular case. Return to older locations if needed, collect missed items, and recheck clues within new contexts.
• Go to the gate and have your keys ready to unlock it with the right tools. Once you have a key, you can move into new areas containing more clues or essential objects.
• Place the plug part on the checkpoint window to see whether anything will happen when it is placed there; maybe something underneath will open up.
• Climb inside the checkpoint to search for additional evidence or tools that may have been stored there; take 1/3 of the piece from the checkpoint since it’s most likely one of the parts of a big puzzle or device.
• Complete this puzzle to unlock more progress during investigations. It will lead you toward some vital evidence/tools. Knives should be taken from the jitter’s prize area to help with obstacles, cutting, or analyzing evidence.
• To access the investigation scene further, pass through the puzzle by solving each step at a time. Dig through the rubble with it for any hidden evidence that could make or break your case.
• Check under the stove for hidden nooks and crannies. Besides, pick up the bucket and rope next to the oven. They can be used to hold things or fashioned into makeshift tools.
• Maybe you can splash coal onto the boiler using a shovel; this might lead to starting up some machine or shining light on hidden evidence retained by heat.
• Look at this grate, see if it is removable, or give any clue that it might be under. You may consider taking (the valve) out of these vents since it’s one of those things that could fit into machinery or combine with other parts in an attempt to solve puzzles.
• Place that wheel where it should go before advancing deeper into inquiries or activating machines. You need to check whether items inside this barrel are immersed so much as the water tank is concerned.
• Take a piece floating or at the bottom level of the barrel using a pail. So you use a pail on the boiler to fill it so the steam can be generated and the mechanism can be implemented.
• The last part must also be put somewhere correctly, but only after finishing the puzzle and repairing some technicality hindering progress.
• Rotate the valve clockwise until fluid begins flowing out, enabling someone to proceed with further investigations.
• Many quests originate from releasing particular objects when valves are activated. Ensure that such items will never fall short in future assignments.
• Furthermore, if you put this part right where it is supposed to be, machines will look fine, and other things requiring attention will be over.
• Take the chisel from where it is now accessible since you can use it when carving or breaking through. Grab a wrench from that part, suitable for unscrewing bolts and fixing the machine’s breaks.
• The wrench on this grate can be used to unscrew it and see what else is hidden here, which can be useful for breaking through a hook with a chisel or obstacle.
• A wrench should be applied to remove the grate by loosening it; something may appear below. Use the rope on the hook to retrieve any reachable item or fix them securely at a distance.
• Hook and rope are joined together, forming a grappling tool meant for pulling items while being secured far away. Using the fishing line, pull out the canister, which could contain essential items, even if it had been used as fuel.
• Going towards a workbench would allow manipulating things gathered to create or repair something. If you go to the workbench area, pick up a light bulb since one might need to brighten up dark rooms, activating machines occasionally.
• Piece two may also be located after cracking open something using a hammer before putting its content somewhere in particular.
• Connect hoses to machines or pour fuel into canisters. Return to previous places, review old evidence in a new context, or use newly acquired items.
• Employing the items and information gathered during the investigation, proceed to new regions. With a knife, overcome hurdles that hinder moving forward or open up unseen compartments.
• Use a ladder to get access to high-up areas that contain vital proof. Take bits of information from the site, possibly a puzzle piece or something important.
• You can explore the mine further by supporting various machinery using a fuel canister. You should refill equipment, including cars, using a gas cylinder, thus allowing us to proceed further in the study.
• Start the train to move within it through the mine, exposing more evidence in the course. Turn right and search through this area until you find the necessary clues.
• Fix light bulbs to illuminate these areas and reveal hidden things when least expected. Click rocks, then remove the bag containing essential proof before obtaining a knife
• Add stuck bullet 1/4″ to your collection of hints because it has been captured on paper only. Check the faucet for possible usage or opening compartments underneath.
• Set ladders in higher places where retrieval of clue 2/4 “cut rope” is possible. The key from the bag will help you unlock other doors, allowing you to explore well-known territory further.
• Return to former locations to examine something afresh or utilize recently obtained equipment. Accessing these rooms using keys will help you advance further in your investigations.
•  Take an axe like mine, which miners used to smash away barriers defending secret evidence. To collect small or delicate pieces of evidence, take the evidence envelope and tweezers.
• Crucial for identifying suspects, take the fingerprint kit to gather fingerprints from the scene. Advancing the investigation, go to the workshop, and use collected tools and items.
• To complete the machinery or puzzle, unlock further progress and install part 3/3. When you complete the puzzle, it will show new clues or advance to new areas in the investigation.
• Take the screwdriver and drill set from the puzzle reward area for further steps. Let’s go to the Center to use these new tools and items.
• Depending on what needs fixing or revealing, a hacksaw blade could be shown by using your screwdriver to open compartments or repair machines.
• Use the evidence envelope at the mine to obtain a crucial piece of evidence—the gun. This kit allows you to identify potential suspects by gathering fingerprints on a gun.
• Put together fingerprints and guns to evidence, enabling one to conclude according to this criminalistics game manual for forensic science.

Task 3 – Talk to other miners

It’s only logical that they can help us understand how Henry died since they were there. In addition, his colleagues might know something about him that could lead us toward someone who wanted him dead. There is an old tale about Henry’s factory mates about their formecomrade’s ghost that came back for them.

• The solution will bring you closer to critical hints, open up another stage in your investigation, or even provide essential tools.
• Add the fourth clue, “The Dead’s Gun,” to your evidence, which would help you reconstruct the circumstances of Henry’s death.
• Click on the book to find any written information that might give insights, and then ask other miners for their points of view and whether they have any other additional information.
• Proceed forward, looking for Jacob or some crucial evidence and signs concerning him throughout this next area. Find Jacob to learn more about his role and get potential clues from the surrounding scene.

Task 4 – Find Jacob

All surviving crew members may be in danger. However, it looks like he died before the arrival of the detective here. He probably hanged himself because he couldn’t stand such a situation in the mine anymore.

• Jump three times forward while inside a mine or location until you reach another area that might contain clues or required tools.
• This is Lily 1/2, which could come in handy either as a key item for future puzzles or as a means for unlocking hidden areas,
• First, click on the door, then click on the keyhole to examine it closely to see if there are any signs of tampering with it or if there are any hidden mechanisms within.
• Use the newspaper to slide under the door or keyhole to catch the key or whatever you need to throw through it.
• Use the tweezers to carefully extract the key from its keyhole or inside the newspaper without damaging it.
• Go inside to explore any new areas revealed by these keys, which may lead us to find more clues or evidence regarding Jacob’s death.

Task 5 – Investigate the Jacob’s death

InvestigatJacob’s death thoroughly. There was that charcoal palm print. Jacob was accused of killing a miner 5 years ago; nevertheless, he was set free on trial. Can it be that the dead ones are taking revenge? Collect all available evidence to know what happened that led Jacob to his death.

• Use the tweezers to get hold of it, being very cautious so as not to tamper with evidence on top.
• Use your screwdriver on the painting and check for concealed compartments behind it and other possible sources of information.
• Find out where foreman Michael is so you can interview him for clues about what happened.

Task 6 – Find Foreman Michael

Some crew members survived, but they might be in danger now. You should tell them immediately about this fact. Besides, there are no more forepersons now.

• Tear the 1/2 sheet in half to create a more extensive document or, if needed, solve a puzzle. Remove the wheel from the table. It may be part of a bigger mechanism that needs to be repaired.
• Take matches from the table or somewhere near it because they might help us light something up or burn through some obstacles.
• Use the picture to compare the evidence on your desk or solve the riddle by pairing the facts. Click on the puzzle to solve, starting with this picture and including any other clues you have found in your inventory.
• Finish putting together these puzzle pieces to get new areas open for exploration. This will give access to hidden evidence crucial for investigation purposes.
• Take heraldic lily 2/2, which complements its twin required in future puzzles and mechanisms.
• From among them, take one ” handprint, ” 1/5, and put it into your pocket along with other clues you collected.
• Use a knife to rip through barricades while revealing concealed compartments, thus giving evidence 2/5 “sleeping pills.”
• Click on each mailbox you see and check whether there is any letter inside it that could serve as significant proof of something.
• Use the blade cautiously to take out five chips (one-fifth) from the mailbox without causing any harm to the proofs contained within them. Use care when extracting fragments number one-fifth from the mailbox using a knife, not damaging any evidence.
• Add a piece of ” letter” to each clue collection and ensure they all join logically. Let’s go to bed now and try to find out if there are hidden partitions or materials linked to Jacob’s death.
• “Rope” clue 4/5 should be taken from the bed area; it might serve as a key to understanding how the death occurred.
• Move ahead and look for any signs of final pieces of evidence. Turn left to review other areas or reconsider places with new instruments and understanding.
• Find the ” handprint,” which is ¼ in size. It will be your clue number 5. Add this to your evidence collection to complete the picture of what happened.
• Remove the gear to examine its mechanisms behind or gather more clues. Use the knife to retrieve the wallet with vital information and proof.
• Return to earlier areas to reevaluate the hints or use newly obtained items while you learn about them. Enter the next area through the archway, being cautious about concealed routes or hints leading into it.
• Go down there for more investigations. They may be able to provide you with other supporting evidence, such as tools that can help you understand how everything was. Take a bicycle spoke, which could be handy when picking locks or doing delicate work on something.
• Proceed forward and continue your quest. Watch for characters or things to interact with. Talk to the lady to collect information on recent events or get new hints.
• Enter into the bar, hoping to find more characters you can talk with who may possess hidden evidence. You can speak to a different woman in the bar if she knows something about this situation or if she has some valuable objects.
• Give her a wallet so you can trade it for rum, which may be used to make friends with others. Give rum away to another character and get a rope ladder to help you go up and down in the game.

Task 7 – Get to the lighthouse

• Go towards the bridge because you might want further investigation, possibly needing a rope ladder for progressions. Climb down using a rope ladder onto the lower area and investigate more.
• Click on the corpse to check whether any foul play or additional facts are available; what happens after clicking on the body? You can take the key from the corpse, unlock doors leading somewhere else, or control mechanisms.
• Open car doors as there could be hidden objects within its interior of possible leads, and remove 1/4 of the stones since they are likely puzzles or keys for opening something.
• With a hacksaw, destroy barriers to explore new levels. Take the valve, which may be part of any mechanical system that needs repair.
