A dead billionaire. A hidden fortune. 28,000 possible passcodes. Only one can unlock the safe.

A bestselling mystery writer has died, leaving more than £100 million in gold locked inside a safe – and one final twist in his will. His children won’t automatically inherit his fortune: everyone has the same chance to claim it. Somewhere among the 28,000 six-digit codes in this book is the one passcode that opens the safe. Following a series of rules, readers must use logic and careful observation to eliminate the codes that can’t be right until only one remains. No advanced maths or specialist knowledge is required – just patience, persistence and powers of deduction. An immersive, screen-free elimination puzzle with 28,000 possibilities, one answer and a fortune at stake.
