Creepy old Heikichi is being cagey about his "secret" in Famicom Detective Club: The Missing Heir, but you can make him spill the beans.

As part of our Famicom Detective Club guide, we're here to help you figure out how to progress.

Ask him about everything

He'll say he has a "secret" about Yukiko.

Ask about Yukiko again

Genshin will give the game away.

Examine your surroundings

Yukiko's not here.

"Call" Yukiko a few times

Nice try, buster. Heikichi wants a compliment.

"Call" Heikichi

You'll tell him that he's very handsome. If this doesn't work, try showing him the hand mirror first.
