Five-O races to find the witness to a hit on a bagman of a local mob. The witness, who narrowly escaped being killed himself, had dropped a library book with his library card inside, providing the hitman with the name of the witness. The witness's wife doesn't want him to go to the police. Five-O's main clue is a letter the witness wrote to the Honolulu Star-Bulletin's "Secret Witness" feature that seeks tips for unsolved crimes.
