The Secrets of Kellogg’s House
Now that you and Nick are becoming acquainted, he invites you for a sit-down chat about Shaun. Apparently a man named Kellogg could be involved. Head over to Kellogg’s house in Diamond City. The front door is locked.
Unlock the door by using a bobby pin (Master) or by visiting the mayor’s office and asking for the key. They’re understandably reluctant to hand out keys to strangers. Unless you bribe Geneva the receptionist with 250 Caps.
You enter Kellogg’s house and poke around—literally, as there’s a button under his desk to open a secret door. Press it.
Inspect the secret room for clues, including Kellogg’s favorite brand of cigars. Exit and meet with Dogmeat. Show him a cigar to pick up the scent. Nick heads back to his office, though he can tag along with you if you wish.
