New York - Thank Bernie Madoff.

After two seasons plumbing other areas of sin and corporate corruption, the new season of FX's legal thriller "Damages" stands to make a killing in investment rip-offs.

Why not? A Bernie Madoff-scope Ponzi scheme destroys people while driving some of them to destroy others. It exposes dreadful secrets: Some people discover they're not rich, but broke, while others are revealed to be morally bankrupt.

This becomes a perfect showcase for drama, especially through the dark lens of "Damages." Its Madoff-inspired story line is guaranteeing viewers a rich payoff.

The 13-hour season airs its third episode Monday at 10 p.m., and already it's delivering dividends.

We already know that high-stakes litigator Patty Hewes (series star Glenn Close) is mounting a class-action lawsuit on behalf of the victims of financier Louis Tobin, whose fund everyone in New York wanted to get in, and who bilked his investors for billions of dollars.

We know that Patty's one-time protege, Ellen Parsons, has left Hewes & Associates for a job in the New York district attorney's office, where she, too, will have Tobin in her sights.

But we know that Ellen (co-star Rose Byrne) will re-ignite her complicated, even toxic, relationship with Patty, who, after months with no contact, sends Ellen a peace offering - a $3,000 Chanel handbag - that leaves her perplexed. And disturbingly pleased.

We know that Tom Shayes, Patty's loyal law-firm lieutenant who is helping her build the case against Tobin, has been granted partner status by Patty in her firm.

Shockingly, we also know that Shayes (Tate Donovan, an original cast member) will be dead six months from now. We've seen the body, recovered by detectives from a riverside trash container. And we know bad things led up to it: He, too, was one of Tobin's investors. Shayes, his wife and their extended family - all of whom trusted in Tobin's Midas touch - lost everything. Also looming ahead: Someone seems to be trying to kill Patty.

"Damages," which from its start was a jagged thriller mixed with a plush melodrama, has sometimes seemed a tease in how it parcels out clues to what's going on. But the truth is, the answers come thick and fast. The challenge for a viewer - and it's thoroughly pleasurable, once you're hooked - is to puzzle out what the "answers" mean.

"Damages" has always been sly in its use of flashbacks and flash-forwards. This season, temporal polarities jockey between the here-and-now and what the show's title card identifies as "6 MONTHS LATER." Dizzying? Just keep your eyes on the screen. Addictive? Just you wait.

As in past seasons, the cast is splendid. Both Close and Byrne make good use of their respective character's complexities and contradictions.

The show's crack ensemble is further nourished this season by new members of its supporting cast. Campbell Scott plays Joe Tobin, the tormented, straight-arrow-ish son of the con man, who himself is played by the distinguished stage and screen actor Len Cariou. In a sleek, sharklike performance, comedian Martin Short is the family's attorney.

As the wife of Louis Tobin, Lily Tomlin is unbowed by the scandal. Declaring that her legal deposition went well, she sums up Patty, her interrogator, as "not particularly sharp, that woman."

She couldn't be more wrong.

Patty Hewes is many things, sharp being paramount among them. Same for her evolving nemesis Ellen.

As "Damages" rips into a new season, Patty and Ellen clinch what is perhaps the most impressive aspect of the series. This is a show about two enigmatic, powerful women who alternately go head-to-head while finding themselves in tandem against other, even more menacing threats.

A generation ago, the groundbreaking cop drama "Cagney & Lacey" was saluted for pairing two women as its series leads. Here were NYPD detectives as sisters who solved the crimes.

These days, "Damages" ups the ante in ways unpredictable and wily: two women who collaborate while, as the situation warrants, trying to bring each other down. A viewer gets in on a deal like this and can't lose.
