    The 6th location is above the clockmaker… yw 🙂

    1. K

      I’m above the clockmaker and there’s still no 6th location. Using eagle vision, running up and down seeing I’ve missed anything but I haven’t. It’s still not showing up :/

    2. K

      I still can’t find that last location. I’m above the clockmaker on the roof, using eagle vision, looking through all of the clues and I’m yet to find the location. I think it’s bugged because I’ve got 5/6 locations, found all the clues for 5 locations and yet it’s still not shown on the map as a magnifying glass.

    3. K

      Ah, found it! It’s through the window into the Lab!

  2. A

    Wait…. so who did it?

  3. P

    The Solution is: Colonel Charles Ludre De Frolois from the Science Academy

    1. Cheers. Thank you for the solution.

    do we have to progress to a certain part in the story to do this? I pre ordered the collectors edition, have installed both the chemical revolution (which I just completed) and killed by science but when I go to the statue where the body should be there isn’t one.

    1. I actually got this one right after the first one – Murder Foretold. Have you completed this one?

      1. L

        Thanks Lokesh! I didn’t realize there was a series of those murder mysteries! Thanks for the help!!

        1. Hehe, no a problem at all.

    Do we need to explore all locations before accusing someone? Or can we accuse someone once we found them?

      You can accuse them right away but you get less reward money if you do not find all clues and locations.

    oh my gosh dude you have helped me so much throughout this game, espedi ally the riddles, kudos for doing all the ground work then posting it, thank you

    How were we ever supposed to find that lab without it getting marked on the map? Furthermore, how does it show that the Colonel is the guilty one? I can see how its narrowed down to all who is on the list for the science contest-plus perhaps a jealous gf. But that GF (Pauline) isn’t available. So you narrow it down to the ex-military guys that walk with a limp-unless the inventor was framing them- I suppose that you pick the colonel because he has the ballistics and science background. But another guy who is not in here is Gaspard Monge, who’s book was in the lab, and was a contestant. No motive was ever given about him, but also the same for the colonel, because he won’t speak with you. Were choosing the colonel because he’s ex-military, a cripple, has the background, and is a dick and won’t talk.

    1. S

      Right? I was wondering too! I totally thought they should have done Pauline as sort of a twist cause it really has nothing to do with the competition.

    i say the same about this plot line conviction. im not artillery expert but like any kind of projectile weapon (even for back then) not two pieces of equipment were the same. the fact that the seargent fails to mention anything discussed about the cannon doesnt help and is pretty inaccurate. it would make it infinite more sense that the clockmaker was responsible because he alone would have had supreme knowledge of the use and control of it. not to mention most to gain also being a member of the contest with the colonel and the lab worker discredited. smells like someone has a beef with ex-military rejoining life after service. either that or just piss-poor plot writing

    1. A

      Pay attention to the position the cannon is facing in this case. You’ll notice it is facing toward the clock maker’s laboratory. Why would the clock maker try and destroy his own equipment? The only other suspect with a cane is the colonel, who, if you paid attention to the case, is also an accomplished chemist. The colonel knew what the combination of potassium and water would do. He knew that there was a convenient flask of potassium sitting dangerously close to a bunch of water barrels. He was trying to use this to destroy the clock maker’s equipment and take him out of the competition. Unfortunately, there was an innocent bystander meeting up with a “friend” at the same time the cannon would be fired. The plot of the victim is there to try and throw you off of what actually happened.

    I completed this mission (I believe) ages ago. I just went back in to get 100% and this mission is completely greyed out, no body, and uplay says ‘good to go!’ Am I glitches out of my 100%?

    Just a side note to any completionists out there; the Competition Handbill when found at the laboratory is added to the database as VICTIM’S HOUSE- Competition Handbill, the same as when you find it at the actual Victim’s House. So if you’re counting entries to make sure you didn’t miss anything, don’t worry if there is no LABORATORY- Competition Handbill. (had to add this for all the OCD’ers out there, since Murder Mysteries aren’t replayable)
