The Dawn of a To-morrow

A despairing man plans to end his life in London's slums on Christmas Eve, but the innocent faith of a poor orphan girl named Glad gives him a reason to live. Readers who enjoy Frances Hodgson Burnett's other novels would like this short story. Note: the supplied metadata looks off — this novella was originally published in 1906 (1996 may be a reprint date), and it is generally classed as adult fiction, not a children's book.
