As Riley's investigation, with Sanger's unethical assistance, intensifies, they begin to focus on Deputy Attorney General Paul Gray (Philip Bosco). Figuring that a key found on the victim's body has something to do with the Justice Department (where Quinn worked), Riley and Sanger break into the file department there late one night and try to find what the key unlocks. They find a file cabinet containing trial transcripts from federal cases from 1968 that Quinn was in the process of transcribing.
