"The director said, 'OK, Sharon, how do you feel about wearing no makeup, having a terrible haircut and wearing terrible clothes and playing this woman?'" she recalls in a lobby bar at a hotel here.

The role was that of dumpy policewoman Barbara Havers in Elizabeth George's "The Inspector Lynley Mysteries."

"I'm not saying I was pretty, but it was one of those things that was pitted against me. They said she should be someone who's really quite awful looking. But the director was quite adamant and he said, 'You've brought the right element to the character,' which was then echoed by Elizabeth George, thankfully. But for my natural, most glamorous years ever, I was ugly looking."

At last Small wreaks her revenge. In BBC America's absorbing "Mistresses" (airing Fridays at 9 p.m. EST) she wears eyeliner, cavorts in a red bustier and enjoys a lusty affair with a mysterious gent.

Strangely enough, the real Sharon Small isn't anything like either of those characters. She's timid in interviews and frets, "How am I going to answer these questions? I'm quite shy and you worry that you're not articulate enough or that you can't get your point across in the right way, whereas when it's written for you, the character does that for you."

In fact, her shyness is part of the reason she's an actress. "It's a nice escape from real life," she nods. "I'm not actually a natural show-off. I'm chatty, but I'm not a natural show-off, so weirdly you'd think acting is about showing off, and it's not. It's about escaping into another character. I remember the first time I did it I remember thinking, 'Oh, this is a wonderful way of expressing without putting myself on the line.'"

Small was born in the tiny Scottish resort town of Kinghorn (just north of Edinburgh). Her mother held down three different jobs at various times and her stepfather owned small catering vans.

She secretly longed to be an actress. "We didn't have any money at all when I was growing up, so it just wasn't an issue at all. It wasn't going to happen. I think I just sort of harbored it very quietly to myself and then when I was about 16 and it started coming up, 'What do you want to do?' ... I got asked once and I said, 'I think I want to be an actress.' And my mom said, 'WHAT?' And where I come from I hadn't grown up in that kind of environment at all, so it was a big surprise."

The oldest of five, Small's childhood was troubled. "We didn't have the most harmonious home life at the time and my mum did a fantastic job, but it can have an effect and it affects how you conduct yourself for the rest of your life," she says, "and how you conduct yourself in any given situation _ where you put your status, where you might have an inferiority complex about certain things. So you spend a lot of your life trying to overcome that, I think."

Adolescence was very difficult. "It happened very fast for me, I became a woman over the summer holidays and I'd suddenly turned into a very curvy girl. I was still the girl going out on my bike and my skateboard, but I was a woman and being treated very differently. I found that very hard to deal with and lost a lot of confidence there.

"I took a long time to recover from that," says Small, who's wearing a Harris-tweed jacket and a white-and-brown printed blouse.

She struck out for London when she was 19, determined to study drama. She worked in bars to earn her keep. "I left home on a night bus and school didn't start for two weeks but I had 10 pounds (about $5) in my pocket and went overnight on the bus and took all my stuff with me. My mom waved me off, but I had no idea what the future held then. I have two sons now I just wouldn't let them do that," she laughs.

In fact, she sobbed when she had to say goodbye to her 2 ½-year-old and 7-month old boys to come to L.A. She left them in the care of their father (to whom she's not married), who quit his job in the exhibition trade to become a stay-at-home-dad.

"He really stretched, being this dad, in a completely different way," she says. "My way of conducting my (child) care was probably much more about learning constantly, just nurturing in a different kind of way. Whereas he will get down and dirty and rough and tumble with them and make stupid noises, and they laugh. So I saw the benefits of what was so good about him being with them."

"The Reaper," CW's revenge on "Touched by an Angel," returns to TV on March 3. The wicked little show stars Bret Harrison as the Devil's reluctant servant who learns that he might be the son of Old Lucifer himself. When Harrison was first starting out in Hollywood he met another would-be actor, Adam Brody ("The O.C."), and the two of them shared an apartment.

"He became my best friend and we lived on Yucca in the ghetto of Hollywood," recalls Harrison. "And finally we ...
