In Sheep's Clothing

In Sheep's Clothing is a quest in Fallout 4.

Quick walkthrough
This quest starts when the Sole Survivor reaches level 40 and travels to Diamond City. Mayor McDonough will be seen shooting a security guard and fleeing to his office, where he takes his secretary hostage while Piper chases him.

Detailed walkthrough
1. Chase McDonough to his office. (Optional) Talk to a doctor and bring him to the wounded guard.

2. Break into McDonough's office and confront him with Piper.

3. Decide how to deal with McDonough. Passing a medium difficulty speech test will make him release his hostage. He will then request that the Sole Survivor allow him to leave the city, giving him or her the option to comply, kill him on the spot or make him stand trial, starting a fight.
