In a ho-hum TV season, in which most new shows have been greeted with a collective shrug and a click of the remote control, CBS's freshman The Mentalist has managed to deduce what viewers want.

It offers tousle-haired charmer Simon Baker (The Guardian, The Devil Wears Prada) as Patrick Jane, a faux psychic jolted by personal tragedy into new-found ethics and a job helping California state crime fighters.

There's the appeal of a mystery wrapped up within each episode, joined with Patrick's quest to catch the serial killer who took the lives of his wife and child.

And there's creator and executive producer Bruno Heller, fresh off the triumph of HBO's miniseries Rome and looking for a new challenge, who's deftly mixed a traditional whodunit with the journey of an emotionally wounded hero.

During shooting on the Warner Bros. lot recently, Baker looked very much the part of the carefree actor with a hit series.

He blithely pedalled a bicycle, a gift from his family, between his studio trailer and a cabin standing in for a witch's house.

Asked to dissect the appeal of The Mentalist, however, Baker was far more cautious than flip.

"I don't want to touch it. I'm really happy. Knock on wood. ... This day and age, it's a very competitive world, the television world. If people want to turn the television on and watch The Mentalist, then I'm very, very happy."

So are his wife, actress Rebecca Rigg, and teenage daughter, he added, who were the first to tell him The Mentalist had a shot. The Australian-born Baker, 39, also has two sons.

Robin Tunney, Tim Kang, Owain Yeoman and Amanda Righetti co-star in the drama, airing at 9 p.m. Tuesdays.

For his part, Heller is glad to heap praise on Baker for the show's out-of-the-gate top-10 ratings performance, with weekly audiences of about 16 million.

"He's a genuine TV star, and we were very lucky to get him. Especially in tough times, he has the kind of positive spirit and sense of life that appeals to people," Heller said, adding, "I think the camaraderie and family feel of the ensemble works very nicely. But beyond that, it's a mystery."

Other shows incorporate supernatural elements, whether framed as real or fraudulent -- think The Ghost Whisperer, Medium or Psychic. But The Mentalist is cut from different cloth, say Baker and Heller.

"This show probably draws more parallels to Columbo than to series with an otherworldly tinge, Baker said. "My character just has a different way of looking at things. He looks at things outside of the box."

To clarify Patrick's skill, Baker notes that "a mentalist doesn't have powers. A psychic does. A mentalist has power to suggest ideas to someone," akin to a professional magician such as Criss Angel.

The Mentalist isn't about "whether you believe or don't believe that people have powers," Baker said.

Heller drew his inspiration for the drama from the streets of Los Angeles, where "every block has a storefront" with a psychic.

"There's an interesting moral ambivalence in people who do that job, who say they can get in touch with the spirit world or say they can read your mind," he said. "In one way, I think it's rubbish. ... But on the other, they're performing a genuine therapeutic function in people's lives."

In contrast to forensics-heavy shows such as CSI: Crime Scene Investigation, Baker welcomes the fact that the mind, rather than the microscope, is his character's weapon of choice.

"It brings the crime-solving back into the fabric of human nature, so it's prescience in the sense those old shows were. It's more about reading someone. As an audience member you can sit there and meet all the potential suspects ... so the audience gets involved in the show."

When the series began production, Baker waved away suggestions he conduct research into weapons training and other aspects of police work.

"I'm not a policeman. I'm not that guy. I'm not even officially a detective. I'm a consultant that uses my powers of observation and ability of suggestion to influence people's thoughts and ideas to solve crimes," he said.

"It's best I make as many police mistakes as possible, because it creates something interesting within the show. If I do the wrong thing, it gives them (his colleagues) something sort of to react to and play with."
