Who Took The Diamond?

A rare diamond has vanished, and only ten people even knew it existed. Now it is your job to find out which one of them took it, and where it is hiding.

Who Took the Diamond? Review the Suspects, Follow the Money and Find the Missing Gem is a full length interactive murder mystery puzzle book that puts you in the role of lead investigator on a case with two questions to answer instead of one. Amateur prospector Jack Robertson spent eleven years searching for valuable stones at a small private diamond mine. On an ordinary Saturday, he pulled an extraordinary rough diamond from the screening trough, a stone so large and unusual it was worth millions. Overwhelmed by the discovery, he told exactly ten people before the stone could be properly secured. Within days, it was gone from a locked safe that showed no sign of forced entry.

This is a complete investigative case file built for readers who love true crime documentaries, forensic shows, and puzzle books that reward close attention. You will study a detailed diamond profile explaining the stone's unique natural markings, review the mine's full security plan and its one overlooked weakness, and meet all ten people who knew about the discovery before it disappeared. Every one of them has some combination of motive, opportunity, financial pressure, travel history, or specialized skill that could point to guilt, and most of what looks suspicious will turn out to mean something other than what it seems.

Along the way you choose one investigation specialist, a gemstone and mining expert, a financial and behavioral investigator, or a travel and logistics analyst, and each hands you a different packet of clues. You will review complete financial profiles and travel records for every suspect, a skills and capability comparison chart, full witness statements, and detailed interviews with all ten people involved. You will study a numbered evidence inventory, a list of possible hiding locations, search and property reports, and tips submitted by the public, some credible and some not.

Once you believe you know the answer, you record your full theory on a dedicated accusation worksheet, naming the thief, the motive, the method, and exactly where the diamond is hidden. A bold stop divider stands between your final answer and the truth, so you will never accidentally see the reveal early while flipping through the book. Turn past it only when you are ready for the complete official solution, a full breakdown of every clue and red herring, and a dramatic final retelling of exactly how the theft happened and how the diamond was found.

Inside this book you will find a suspenseful opening story of the discovery itself, a detailed profile of the diamond and its one distinguishing natural feature, a full map of the mine property and its security blind spots, complete dossiers for all ten suspects, separate financial and travel record sections for every person involved, a skills and capability matrix, witness statements and full suspect interviews, a numbered evidence inventory, three selectable specialist paths with unique clues, a list of search locations and property reports, submitted tips of varying credibility, a section on how a stolen gemstone actually moves through the black market, new evidence uncovered late in the investigation, a final suspect comparison chart, a protected solution reveal, and a final investigator scorecard so you can rate your own case from curious prospector to diamond recovery expert.

Perfect for fans of true crime, heist stories, escape room style puzzles, and armchair detective games, this book is meant to be worked through slowly with a pen in hand. Track the money. Track the timeline. Trust the evidence over your first instinct. Ten people knew about the diamond, and only one of them knows where it really is.
