The Midnight Man (1974 film)

The Midnight Man is a 1974 detective film codirected by Burt Lancaster, who also starred with Susan Clark.

A coed Catherine Bach is murdered and the local sheriff, Casey Harris Yulin, tries to pin the crime on a creepy college janitor Charles Tyner who spouts Biblical revelation while hiding pornography. Slade has other ideas and pursues an unauthorized investigation of his own. Taking the lid off the hornets nest involves him in considerable danger as blackmails, beatings, attempted rape and further murders wrestle for screentime before the long andovercomplicated drama grinds to a close. The murdered student turns out to be the daughter of Senator Clayborne Morgan Woodward, who subsequently receives blackmail letters over his daughter Natalies confession to her campus psychiatric department counselor about an incestuous relationship with her father. Incriminating cassette tapes of the account have fallen into the hands of the blackmailers. Slade questions possible suspects including Natalie Claybornes estranged boyfriend King, played by Burt Lancasters son, William, who declares to Slade that the generation gap just got a little wider, and Dean Collins, the psych professor played by actual Clemson faculty member Harold N. Cooledge Jr., as well as a nerdy student whose taped psych rant was also stolen and Senator Clayborne himself. ........
