Just a free, unsolicited plug for the author: :D
(from the story description)
Synopsis: When Martin's life falls to pieces, his sister Kate comes to his rescue. She practically drags him to London, where he is cast for a commercial. From that point on, his life will never be the same. But as Great Britain falls in love with his character, an enigmatic butler called Carstairs, an inexperienced Martin falls in love with the wrong woman. A moving story with romance, sex and LOTS of laughs.
Ron Dudderie is the author, and if you haven't started reading this serial, I really recommend it.

Ron is posting weekly installments on SOL. No worry about it falling into the incomplete/inactive list as the story is complete, along with two completed sequels. I became impatient with waiting for the free weekly installments, so went to his website and bought all three. :D Money well spent, IMHO. Although I love reading for free, if the story interests me enough, I will pay for it.
