The hitman forces Holly to write a letter, because he has to kill her, simulating a suicide. When Holly wrote the letter, he takes her sleeping pills and forces her to swallow them. He keeps her handgagged again, until she faints.
The man takes a nylon bag and puts it over Holly's head. She wakes up. He keeps his gloved hand over the bag, so she can't breath under it. The hitman has no mercy and suffocates her to death.
