"In Death Constant beyond Love", we get a picture of what Senator Sanchez is really like. He is a powerful money hungry man who finds out he is going to die. He does however become very intrigued by Laura Farina. The senator's erotic love for Laura is an illusion because he is left with solitude at the end of the story. Senator
"The senator caressed her slowly, seeking her with his hand, barely touching her, but where he expected to find her, be came across something iron that was in the way. What have you got there? A padlock, she said... He told me to tell you to send one of your people to get it along with him a written promise that you'll straighten out his situation" (Garcia Marquez 2854).
This did anger him but also it made it a little easier for his depressed state of mind to become an actual reality. See Senator
In conclusion this story is of power and money but it is also about a man who is told that he will die. He loathes having someone by his side when he dies. He likes Laura's beauty and grace. He is dilusional though because his erotic obsession for Laura might be the only thing that eases him at his time of death. Laura is using him to get something for her father.
