Steal necklace from the Merchants

Steal necklace from the Merchants is a side quest in Fallout.

Detailed walkthrough
In the Hub's Old Town is a building with a staircase that leads down to the Thieves' Circle. The Vault Dweller must pass some traps and locked doors to find Loxley and his thieves.

Loxley will give the Vault Dweller credit for navigating through the defenses and extend an offer of membership to the Thieves' Guild, provided that they steal a necklace from the house of an eminent local merchant. Completing the initial dialogue and accepting this quest will grant 900 XP. If Jasmine is spoken to, she will give the Vault Dweller some supplies for the mission.

Daren Hightower's home can be found in the Heights district of the Hub. His house is heavily guarded, but if the Vault Dweller sneaks in at night (around 6:00pm), they should be able to make it in and out without being seen. Alternatively, during the day, the Vault Dweller can talk their way past the first two guards by saying they need to speak with Mr. Hightower, and then entering combat to avoid Mr. Hightower's dialogue.

If the Vault Dweller gets caught sneaking in, they may have to kill the guards. In any case, the objective of the mission is to get inside a room toward the lower left of Hightower's house. Inside one can find a strongbox, protected by a trap that will explode if the Vault Dweller tries to lockpick the box before disarming it (using lockpicks may not work but using lockpicking skill from the skilldex will). Inside the strongbox is the fancy gold, silver and diamond necklace.

Returning it to Loxley in the Thieves' Circle completes the quest.
