Hank Quinlan

Police Captain Hank Quinlan is the main antagonist in the 1958 noir thriller Touch of Evil, directed by Orson Welles, who also played the role.

He is a veteran officer of an american border town that connects with Mexico, and while he does greatly at capturing criminals, his methods are questionable. Quinlan is a widower, and since his wife's murderer escaped from him while he was a rookie -but was later killed during WWI, as Hank himself implies-, he became relentless in his fight against crime, resorting to such tactics as planting fake evidence to get someone arrested. He turned to alcohol for some time, presumably after his wife's death, but then replaced it for candies, thus becoming fat, he also uses a cane since he was shot on the leg years ago; the bullet was originally intended for his partner Peter Menzies, who admires him and helps him in solving cases, it is also implied that Menzies is covering Quinlan to help him in getting away with his underhanded tactics.

When mexican police officer Mike Vargas arrives in town, he cooperates with Captain Quinlan's team in solving the murder of a local tycoon via dynamite. At first, Hank simply dismisses Vargas' observations because he's from Mexico and the explosion took place in the USA (though he might also think of Vargas as inferior because of his nationality). But when the foreigner officer starts questioning his methods, Quinlan would cross the line, secretly associating with a renowned crime family to try and put criminal charges on Vargas' wife, Susie, in an attempt to discredit him.
