Set in San Francisco in the crumbling vestiges of Italian North Beach. Before becoming a private investigator, Dante Mancuso worked for a secret corporate security firm that prized effectiveness over legality. When he left, it was not on good terms, so he made sure to take enough inside information to keep himself safe from reprisal. When SFPD Detective Leanora Chin starts asking questions about his cousin Gary's family warehousing business, Gary turns to the security firm for help, which they're willing to provide, so long as Dante agrees to settle his past debts by doing them one last favor.
