G. K. Chesterton 
Manalive 

Perhaps the most light-hearted of all Chesterton’s 'serious’ works, Manalive pits a group of disillusioned young people against Mr. Innocent Smith, a bubbly, high-spirited gentleman who literally falls into their midst. Later accused of murder and denounced for philandering everywhere he goes, Smith prompts his newfound acquaintances to recognize an important idea in most unexpected ways.
