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 you cross the bridge into the remains of the city, look for signs pointing you in the direction of the Diamond.

At the entrance, you run into a reporter named Piper. She cons you into fooling the guard with her via the intercom, after which he will let you in letting you in.

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

Who can help you in this bustling market? Most are friendly folks, and asking any of the following provides a clue to your next move:


 * Danny Sullivan (the gate guard)
 * Pastor Clements (of the All Faiths Chapel)
 * Nat (Piper’s kid sister, selling copies of Public Occurrences)
 * Piper (after she interviews you)
 * Moe Cronin (Swatters salesman extraordinaire)
 * John the Barber
 * Artuo the weapons merchant
 * Proprietor of the Valentine Detective Agency

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