All Cases and Quest Solutions

The four cases in Tiny Bookshop are short, but they love to hide progress behind one missing item, one forgotten venue, or one conversation that has to happen on another day. If a case feels frozen, the first thing to check is whether the right case is pinned on the Investigation Board and whether the related clue item is still equipped.

The other common problem is pacing. Characters usually only advance one topic per visit, so a clue chain that should take two conversations can easily spill across several in-game days.

Case Rules That Save You Time

• Keep the Investigation Board equipped. You get it with your first case, and later cases still expect it.
• Pin the active case. Progress only counts for the case currently shown on the board.
• Equip clue items. If a character is supposed to notice a knife, crest piece, or container, it usually needs to be visible in your shop.
• Revisit after a clue. Solving a step often means returning to the same person or place one more time.

The Mascot Murder

• Start it at Mega Marche when Fern shows you the deflated mascot.
• Check the nearby garbage bin until it tips over and drops the knife clue.
• Talk to Klaus outside Mega to learn the CCTV footage was deleted.
• Equip the knife on your wall and wait for the owner to notice it. This is the part most people think is broken.
• Once the owner names the borrower, wait for the borrower to visit and react to the active case.
• Go back to Fern at Mega to close the case.

Stuck here? The knife needs to stay equipped, and the case needs to stay pinned. If nobody reacts, let a day pass and keep the display active.

The Mysterious 7th Rule

• This case opens only after Moira and Maryam argue at the cafe and you finish Maryam's business course.
• Talk to Walt at the Waterfront and buy the B.L.A.B.L.A. book for 25 coins.
• Wait for Tilde to visit and explain who Roderick Blighton was.
• Then wait for Moira again so the lighthouse investigation can advance.
• Meet Moira and friends at the Lighthouse after nightfall, then search the lighthouse itself.
• Take the lost rule back into the story chain and let the follow-up conversation resolve it.

Stuck here? This case is conversation-gated more than puzzle-gated. If Moira does not move, she usually still has an earlier line queued.

Mysterious Noises

• Finish Harper's sandcastle project first.
• Return to Far Beach when the cave roar appears as the active effect.
• Talk to Harper and agree to meet at the cave entrance before you close for the day.
• Explore the caves with Harper to resolve the noise and start the crest case.

This one is fast. If it will not trigger, the usual problem is that Harper's earlier beach chain is not actually finished yet.

The Fragments of St. Bookston

• You begin this while investigating the caves with Harper.
• Keep the Archaeological Container equipped for the later fragments.
• The second fragment is in the St. Bookston fountain near the cafe.
• The third comes from the Bust of St. Bookston, either from Professor Wen's reward or the seasonal newspaper.
• The fourth is at the Castle Ruins graveyard. The correct grave is Sophia Theodosia Bright.
• After all four are found, Harper restores the crest and returns it on a later day.
• Inspect the University statue to find the slot, then meet Harper there with the restored crest.

Bottom line: Cases in Tiny Bookshop rarely ask for brute force. Keep the right board active, keep the right item equipped, and assume one more visit is needed whenever a clue lands.
