6,991 numbers. 21 clues. One hidden answer. 

A substantial sum of money has disappeared, and somewhere inside a collection of financial ledgers lies the number that can expose what happened.

 Welcome to The Missing Ledger, a large-print elimination mystery for adults that combines logical deduction, number patterns and a fictional financial investigation into one enormous puzzle. 

The mystery begins with a short backstory that puts you at the centre of the investigation.

 From there, you are faced with 6,991 number entries spread throughout the ledgers. Your task is simple to understand—but far from simple to complete: 

Study the 21 clues. 

Examine the numbers carefully.

 Cross off every entry that fails to meet the conditions. 

Clue by clue, page by page, thousands of possibilities begin to disappear until only the correct answer remains.

 You will need to pay attention to digit positions, odd and even numbers, digit sums, repeated digits, differences, neighbouring digits and other numerical relationships. 

Leading zeroes count too, so every printed digit matters. 

There is one verified final answer, giving you the satisfaction of knowing the mystery can be solved through careful deduction rather than guesswork. 

A coded answer challenge at the back of the book provides a final way to confirm whether you cracked the case correctly. 

Designed in a convenient 7 × 10 inch format with a black-and-white, large-print interior, the book offers 136 pages of screen-free puzzle solving and plenty of room to work through the investigation at your own pace.
