North Valley Squad Casebook

North Valley Squad Casebook or a NVS Casebook.

Information
The team each uses a casebook for their mysteries. A casebook is a binder with papers or a notebook for noting all the suspects, evidences against them, and clues for their investigations. As Mel said, "solving a case is like putting a jigsaw puzzle together, and the casebook is where (they) keep all the pieces." Basically, a casebook is an effective tool to "start piecing' the puzzle. Organizing stuff, getting it together." Silo would also read whatever was written within the casebook, and then help the team to find more clues. There's also another casebook especially made for Silo to help him figure out who he was.

Make a casebook to keep track of all the clues:
 * Make a page for each suspect.
 * SUSPECT: Who might have done the crime?
 * EVIDENCE: Where was the suspect and why would he or she do it?
 * Make a page for OTHER CLUES.
 * Write facts that may be important to help solve the case.[3]
