Walkthrough

 * 1) Speak to Enthir at the Inn of Winterhold.
 * 2) Travel to Markarth and speak to Calcelmo at Understone Keep . He will not provide a translation of the book. The player must enter Calcemo's Museum to complete the quest.
 * 3) Obtain the key to Calcelmo's Museum by
 * 4) *Completing the side quest to kill Nimhe, a giant frost spider.
 * 5) *Persuasion/intimidation if the player's skill is high enough
 * 6) *Completing the Book of Love quest. This opens additional dialogue to obtain the key.
 * 7) *Stealing the key. It's located on the Alchemy table behind him.
 * 8) *Picking the lock on the museum door.
 * 9) *NOTE: Killing Nimhe avoids comments from the guard at the entrance and hostility from the guards in the first room.
 * 10) Go to the East wing of the Keep and enter the Museum. The guard at the door will tell the player they're not allowed in if the side quest wasn't completed but the guard will let the player continue without further action.
 * 11) Explore the first room. Use the sneak skill to steal or the guards will turn hostile. This area contains many common Dwemer artifacts and books in display cases (expert lockpicking). One of the Stones of Barenziah and a chest (expert lockpicking) is located In the room behind the gate to the left,
 * 12) Make your way up to Calcelmo's Laboratory, from now on you will want to sneak because Calcelmo restricted the laboratory from you and guards will not like seeing you in restricted areas. In the laboratory in an area to the left there is a journal and Spider Control Rod that are worth picking up. After a few moments there will be a guard that will walk through the other two doorways opening them up for the player. Guards seem to be on a set path so try to learn their movements and move around them.
 * 13) The doorway on the left is barred so you have to take the right path. Find, pickpocket, or pick the master lock into the next area of the laboratory. Two guards will be talking and eventually travel down a hallway.
 * 14) *Alternately, there is a pullbar on a column near where the two guards walk. Pulling the bar activates a spinning blade trap which can be used to kill the guards completely unnoticed.
 * 15) You can either follow the guards and sneak by to get to the staircase to the next area, or go the opposite path and get to the stairway. Going the opposite way of the guards will lead you to a hallway filled with a gas that will kill you fast if you go into it. Opposite the hallway is a button that you need to step on to clear the path and run through before the gas fills the room again. You can leave an object from your inventory on top of the button to remove the gas. The Argonian Histskin power can completely negate the damage from the gas. NOTE: Poison resistance does not make you immune to this damage.
 * 16) You'll come to a room with a patrolling guard and Calcemo's nephew Aicantar sitting on a chair in front of a table. At the end of the floor you're entering is a valve that you can activate. An explosion will happen that will kill the guard and make Aicantar flee so you're able to pass and head up to the Tower. If the previous room's guards are still alive they will run into the room after the explosion.
 * 17) Continue along through the next couple of doorways until you see the door leading to the wizard's balcony. In this room there is a Larceny Target called the Dwemer Puzzle Cube, which should be taken to Delvin Mallory for some gold.
 * 18) When you reach Calcelmo's Tower make your way up to Calcelmo's Stone. You will need a roll of paper and charcoal, which are found in abundance in the room before reaching the stone tablet, before activating the stone.
 * 19) Once you receive the rubbing, Aicantar, 2 guards and the City Captain will enter the tower and you will hear their conversation. His nephew insists that somebody is trying to sabotage his uncle's research, and demands that the guard searches the tower from top to bottom.
 * 20) *If you kill Calcelmo's nephew he may have a staff that can command dwarven spiders. If not, try to sneak to the staircase below you on your left, climb up and jump on to the torch nearest to the wall. Leap to the ledge that leads to the exit. (Note: The staff (Spider Control Rod) can be found upon first entrance to Calcemo's Laboratory through the first door on the left, but must be stolen. If taken, Calcemo's nephew will not have another copy of the staff.)
 * 21) *If you have high enough Magicka and Illusion, it's possible to neutralize all 4 hostiles using one or two Pacify area spells. After they are neutralized, you can simply walk out the door and down the waterfall.
 * 22) *Killing the guards and Calcelmo's nephew seems to give no bounty.
 * 23) *Once you get out of the room with Calcelmo's nephew you will be back out on the balcony between the tower and the museum. You will find you cannot fast travel from that point despite being outside. If you want to avoid sneaking through the museum again (provided you stole the key rather than earning it), you can squeeze between a rock on your left as you are looking at the tower staris and a wall. Follow this down to a nice view of the waterfall and drop into the pool below. Your compass will point in this direction, implying that it was the path you were supposed to use to escape. You will be back in Markarth.
 * 24) Head back down to Markarth.
 * 25) Return to Enthir and Karliah at The Frozen Hearth's cellar in Winterhold.

Journal Entry upon completing the quest
''After Enthir successfully translated Gallus's journal, I've discovered that Mercer's motivations transcend simple greed or murder. As a member of The Nightingales, Mercer was tasked with guarding a place called The Twilight Sepulcher, the Temple of Nocturnal. According to Gallus, he defiled the Temple and betrayed the Thieves Guild. Karliah insists that we bring this information to Brynjolf immediately.''

Rewards

 * Nightingale Blade, given by Karliah, previously owned by Gallus Desidenius.

Bugs

 * If you complete Calcelmo's favor of killing the Frostbite Spider Nimhe, and then gain safe entry into the Dwemer Museum and obtaining Calcelmo's key after completion of this quest. You may get the quest a second time. Note, that also means you can get the Nightingale Blade a second time. However, this may cause problems with the quest Darkness Returns (may be unable to finish), therefore it's best not to do it a 2nd time.
 * If you complete Calcelmo's favor of killing Frostbite Spider Nimhe, and then gain safe entry into the Dwemer Museum and you persuaded him to let you in for helping him with his love interest it is possible that you will get this quest a second time the next time you return to the museum, and Gallus's Journal will be 'bugged' in your inventory as a quest item. The quest is unable to be complete on the second run do to the final door at the top of the tower being closed and your key no longer working.
 * If you entered Mercer's house and looted Mercer's Plans before completing the quest Hard Answers, The Pursuit will not initiate upon completion of the quest Hard Answers. This can be fixed (on the PC) by resetting the quest Hard Answers to the last stage with the command [setstage TG06 70], dropping the item Mercer's Plans from your (Misc) inventory, and then talking to Karliah and completing the quest again. Do not pick up Mercer's Plans from wherever you dropped them until the quest The Pursuit is on the stage: Discover evidence of Mercer's location. (i.e. after you break into his house, simply leave and go pick back up Mercer's Plans)
 * Be sure to drop Mercer's Plans from the misc section of your inventory before speaking with Karliah and Enthir after retrieving Calcelmo's notes. DO NOT pick up Mercer's Plans until you successfully break into his house in the mission "The Pursuit".
 * For an unknown reason, if you want to speak with Enthir at the end of the quest, he doesn't want to talk with you. Use the autosave when you got into the building and it'll be good. (Does not work the autosave, you can´t talk to Enthir if you are currently doing the quest Staff of Magnus and Savos Aren is dead, first finish this quest and then return to Enthir).
 * For an unknown reason, if you gain safe entry into the Dwemer Museum, a guard will stop you and initiate the "The Forsworn Conspiracy" dialogue, "Halt you are under arrest for conspiracy and murder..." Any response chosen leads to an infinite dialogue loop where you can neither submit to the guards nor pay off the bounty resulting in a permanent 1000 bounty in the Reach and getting stuck into the dialogue loop every time a guard sees you. (Note that the bug only appeared after the quests "The Forsworn Conspiracy" and "No One Escapes Cidnha Mine" and upon entering the museum killing the guard.)
 * Fixed after **1.04/2.03 Patch** 11/02/2012 I went to he shrine of Talos and the Markarth guards weapons and shields where still there (I killed them during The Forsworn Conspiracy ) I took the weapons and shields and removed them from the Shrine of Talos and got rid of them, completed the quest and had a 1050 Bounty that i was able to pay off. **(PS3 Confirmed)**
 * At the end of the quest, after Karliah tells you to meet her at the Ragged Flagon, Karliah will usually leave the room. However, sometimes she does not and stays in the cellar of the Frozen Hearth forever. Trying to talk to her will only trigger a small quote from her. The quest marker will still lead you to the Ragged Flagon, where all characters stand with weapons' drawn asking why you brought Karliah with you, even though she is not present. It is impossible to continue with any Thieves Guild quests if this happens, and the only solution is to reload a savegame from before you brought Enthir the notes on translating Gallus' Journal.
 * After insciribing the information on the stone, if you stealth past the three NPC's that enter the room, you are able to complete the quest as normal but the quest stage will bug, causing the mission Trinity Restored to bug and be impossible to complete as Karliah and Brynjolf will not appear at the Nightingale Cave. You will also not receive the Nightingale Blade as a reward from the quest. You can attempt to fix this by typing "setstage TG06 200" which will complete the quest Hard Answers. Fast travel to Nightingale hall and wait 24 hours and she should appear.
 * If you have previously sneaked into Calcelmo's Laboratory and stolen the Falmer Translation Guide before this quest begins, it may be uncompletable.
 * For whatever reason, followers that you have with you while entering the museum illegitimately will say "You're not supposed to be in here!" when attempting to talk to them, instead of their usual dialogue. I first noticed this with Lydia, after commanding her to take multiple Dwemer artifacts. At first, she acted normally, but she eventually just stopped talking to and following me. This makes it impossible to get her out of the museum, as when commanding her to go through a door, she simply says "Can't do that, sorry." It is possible to get them to sort of follow you by ordering them to do something by holding the interact button while looking at them. You may have to be a certain distance away to get them to do this. While they will STILL not leave, or talk to you, you can get them nearer to a door, rather than waiting for them to walk to the door by themselves.
 * FIX** To get your follower out of the museum, attack him/her enough times to get her to leave your service. He/she will usually make their way to the nearest door, at which time, they will leave. Afterwards, follow them out, and then ask them to rejoin your service. SAVE before this, just in case you accidentally kill them/get them to attack you. If this does not work, you might have to kill your follower, and acquire a new one.
