"Another one Sir?" The barkeep asked. 

"Please," the man replied, sliding his glass back over to the barman. 

"You seem in a good mood," the barkeep said, keeping the conversation going. It was two pm on a Tuesday afternoon and the place was empty, save for the happy man who kept sliding bills across the counter. 

"Let's just say," said the man, after a lengthy pause. "Things always work out in the end." He started laughing to himself, revelling in the situation. He'd never know. The barkeep would never know that the man who was laughing maniacally had just killed his wife.
