Arthur Wordsmith is an unknown writer and a relatively inexperienced eye doctor whom had served aboard a ship for some time.

In 1889, he receives a letter invitation to the Phantomhive manor, at a party with numerous people of renown stature. The earl appears to be fond of one of Mr Wordsmith's published writings in a relatively obscure magazine, that being the sole reason for his invitation.

Arthur has a steadfast sense of justice and a cool, analytical mind. He has a habit of jotting down notes in the cuffs of his clothing for reference in his novels.
