Loren Visser (Blood Simple) is a private detective hired by Julian Marty to spy on his unfaithful wife, Abby. Visser is always seen wearing a yellow suit and yellow cowboy hat. He also drives an old beat up VW Bug.

The audience’s first encounter with Visser is when he presents the photographs of Abby and Ray sleeping together to Marty at the bar. Abby is having an affair with one of the bartenders, Ray, who works for her husband. As Marty looks over the photos, Marty gets angry at Visser for the way he cracks jokes about Marty’s unfaithful wife. As Marty is looking over the photographs Visser says, “I know a place you can get that framed”. Marty dismisses Visser and tells him that if he ever needs him again, he knows where to find him.

After a failed attempt to kill Abby himself, Marty goes back to Visser. He finds Visser at a hill side hangout for young people to drink and meet girls. Visser is seen smoking a marijuana cigarette. Marty tells Visser that he needs him to do something else for him. Visser responds that as long as it’s legal and the pay is right he will do whatever Marty wants. Marty informs him that what he is about to ask is not going to be legal. Visser willingly replies that as long as the pay is right it still does not matter. Visser then agrees to kill Abby and Ray in return for 10,000 dollars. He then instructs Marty to go fishing out of town for the next few days, and Visser will call him when the deed has been done.

Visser goes to Ray’s house where he and Abby are sleeping together. Visser breaks into the house and steals Abby’s gun from her purse. He then walks around to the outside window and photographs the two together as they sleep. He then doctors the photograph to make it look like the couple has been killed. He presents the photo to Marty back at the bar in an envelope and demands his money. Marty believes what Visser has done and hands over the money. However, without Visser noticing, Marty slipped the photo into his safe and placed a please wash your hands sign in the envelope. Visser then shoots Marty with Abby’s gun and takes the money. At home, Visser burns all the remaining photographs, and this is where he realizes that Marty has kept the doctored photo. Visser also realizes that he has misplaced his lighter. It is a zippo type lighter with his name engraved on the side of it. Visser is desperately trying to destroy any evidence that could link him to Marty. So, he goes back to the bar to try to recover the photograph, but he is unable to break into the safe before Abby walks in to the bar. Visser hides until she leaves.

Later, Ray returns to the bar where he opens the safe and discovers the fake photo of him and Abby lying dead. Ray then realizes that there is a third party, Visser, who is involved in Marty’s death. Previously, he had thought that it was Abby who killed Marty because he found her gun in the room. Ray flees to Abby’s new apartment where hides in the dark room because he realized he is being followed. Visser was the one who trailed Ray to Abby’s apartment. Abby returns to her apartment to find Ray hiding. However, she does not know about Visser and believes that it is Ray who killed Marty. She leaves the light on despite Ray’s request to turn it off because he believes someone is spying on them. Visser then shoots Ray with a rifle from the top of a building across the street. Abby hides and Visser has to break in to the apartment to come kill her, but Abby eludes him. She stabs him in the hand as he attempts to reach across from the bathroom window. Visser punches through the wall and frees his hand, but Abby shoots him while he is behind the bathroom door. She believes that Visser has been Marty to him this whole time. She says after she shoots him, “I’m not afraid of you anymore, Marty”. Visser, bleeding out on the bathroom floor, laughs heartily and replies with his last line, “Well ma’am, if I see him, I’ll sure give him the message”.

Throughout the first part of the movie, Visser appears to be not much more than a comedic buffoon. However, Visser shows his lack of morality when he accepts the job to kill Abby and Ray, but this is overshadowed by the way he fakes their deaths in order to get the money. Visser the makes a drastic turn and reveals how dark of a character he truly is when he kills Marty and Ray. He then attempts to kill Abby, although he never loses his sense of humor throughout all of this killing. This is demonstrated with his last line.
