The Killer Wasn’t Born in January: A Suspect Murder Mystery Puzzle Book with 15,000 D.O.B. Records, 18 Evidence Files, and One Final Killer (The D.O.B. File)

15,000 D.O.B. records. 18 evidence files. One killer.

Inside a locked records office on the California coast,
one of the Mercer sisters uncovered a damaged suspect file tied to an unsolved homicide.

Before she could report what she found, the office was broken into.

The records were torn apart.
The suspect’s name was removed.
Only one detail survived.

A date of birth.

Now the case has been rebuilt from a shuffled registry of 15,000 D.O.B. records
— and somewhere inside that registry, the killer is hiding.

Your task is simple — but not easy:
study the Evidence Files, eliminate every date that no longer fits, and uncover the one D.O.B. the killer tried to erase.

The D.O.B. File is an interactive murder mystery puzzle book built for readers who love deduction, logic puzzles, escape rooms, whodunit games, detective games, elimination puzzles, and satisfying “aha!” moments.

Inside you will find:

• 15,000 shuffled D.O.B. records
• 18 carefully structured Evidence Files
• A true-crime-style case built around elimination logic
• Clean registry-style pages designed for crossing out dates
• Calendar-based and deduction-based evidence
• A final killer reveal

This is not a story you simply read.
It is a case you solve.

Perfect for fans of murder mystery puzzle books, detective games, logic challenges, escape-room-style books, whodunit puzzles, true-crime-style mysteries, and interactive mystery experiences.
