Pattern Recognition01 / The method
The evidence is ordinary.
The pattern is not.
The Proof Ledger is a series of logic-based investigation books. Each case contains a set of clues and a large administrative record: a hotel register, a cruise manifest, a museum inventory, an auction register...
Your task is to search the records, eliminate false leads, and find the hidden pattern.
Read every clue. Assume every detail may matter.
Search the records and test each possible link.
Discard false leads until the pattern remains.
