DEATH WISH By: Lawrence Block

Mark pretended to be suicide and his loved woman’s husband. He tried to jump over the bridge when cop saw him, he visited psychiatrist to talk about his dreams and how desperate he was, he even drank sleeping pills but doctor managed to pump stomach and saved him.

Mark didn’t want to die, just revenge. He bought a gun with fake Edward’s Wright’s driving license and shot Edward, it seemed like a suicide. Mark did it because Edward killed his wife, she wanted to divorce because loved Mark.
