12 CASES. 19,151 REAL LOCATIONS. ONE DEATH THAT DOESN'T LOOK LIKE AN ACCIDENT.

Coffee Never Lies is an interactive murder-mystery puzzle for readers who want to solve the case-not simply read about it. No coffee expertise or outside research required.

For thirty-one years, veteran cupper August Reyner trusted the coffee in his cup more than the paperwork on his desk. When he is found dead at the bottom of a warehouse stairwell, the police call it an accident.

Petra Kessler, his second cupper, is not convinced.

Hidden behind August's manuals, she discovers eleven coffee samples tied to shipments whose official origins cannot be true. Each sample comes with a case file containing a riddle, twelve precise logic clues, and a register of real locations from one coffee-growing [...] INVESTIGATION:Read the Case File: Follow the disputed shipment and watch for the detail hidden inside the story.
Test the Clues: Apply each condition to the real candidate locations.
Eliminate the Impossible: Remove every place that fails even one clue.
Find the True Origin: Identify the single location that satisfies them all.
Follow the Larger Mystery: Track the faint signature connecting shipments that should have nothing in common.

Every chapter is a complete, pencil-in-hand logic puzzle with one verifiable answer. At the end of each case, a QR code and web link let you confirm your solution and discover the real story behind the location.

Together, the twelve cases form one escalating investigation into false provenance, hidden evidence, and the final sample August never meant anyone else to find.
Perfect for fans of interactive mysteries, elimination puzzles, detective case files, geography challenges, and coffee with a darker story behind [...] you uncover all twelve true origins before Petra reaches the end of August's trail?
