A BILLIONAIRE IS DEAD.
AND YOU COULD BE HIS HEIR.
A bestselling mystery writer has left behind more than £100 million in gold, locked inside a safe.

Somewhere in this book is the six-digit passcode that opens the safe. Unfortunately, so are 27,999 other codes. Your task is simple:
FOLLOW THE RULES.
Use logic and careful observation - no advanced maths or specialist knowledge needed.
NARROW THE FIELD.
With patience and persistence, eliminate thousands of possibilities.
FIND THE PASSCODE.
After hours of screen-free satisfaction, go from 28,000 down to one.
