Danger; Or, Wounded in the House of a Friend is a temperance fiction story written by T. S. Arthur,  a popular 19th-century American author. He is famously known for his temperance novel Ten Nights in a Bar-Room.

Author's Preface:

ALL efforts at eradicating evil must, to be successful, begin as near the beginning as possible. It is easier to destroy a weed when but an inch above the ground than after it has attained a rank growth and set its hundred rootlets in the soil. Better if the evil seed were not sown at all; better if the ground received only good seed into its fertile bosom. How much richer and sweeter the harvest!
