Detailed walkthrough
Diamond In The Rough

It seems Diamond City is the best hope for gathering more information about Shaun. Getting there from Sanctuary is a long trek southeast. Once the Sole Survivor crosses the bridge into the remains of the city, they should look for signs pointing them in the direction of the Diamond.

At the entrance, the Sole Survivor runs into a reporter named Piper. She cons the player character into fooling the guard with her via the intercom, after which he will let them in, thus letting the Sole Survivor in.

At the entrance, speak with Mayor McDonough and get his thoughts on Piper. Then head into Diamond City market.

Who can help the Sole Survivor in this bustling market? Most are friendly folks, and asking any of the following provides a clue to the sole survivor's next move:


 * Danny Sullivan- the gate guard
 * Pastor Clements- of the All Faiths Chapel
 * Nat Wright- Piper’s kid sister, selling copies of Publick Occurrences
 * Piper Wright- after she interviews you
 * Moe Cronin- Swatters salesman extraordinaire
 * John- the Barber
 * Arturo Rodriguez- the weapons merchant

Visit the Valentine Detective Agency. It seems the hard-boiled detective Nick Valentine has gone missing. Ellie Perkins hopes the Sole Survivor might lend a hand to help find him. Charming Miss Perkins will allow the player character to shake her down for a few caps upon delivery of her boss.
