"It's in the book . . . but she had marks on her [body]. All of those things lead to the belief that she had slipped and rolled into the water, which makes a lot of sense because the boat -- when they found it, it hadn't been started and the oars were all in the same position. There was no evidence that she tried to get in it."
These days, Wagner and St. John, who have been married 18 years, live in Aspen, Colo., and keep a pied-a-terre in L.A.
He has no plans to retire from acting, though he won't be returning to his guest role as Holland Taylor's paramour on "Two and a Half Men." "I loved doing that show, but they decided to get the guest artists out of the show and go back to the original [format]," he says.
So Wagner's character was killed off on his wedding day -- suffering a heart attack after having sex with his younger lover (Jenny McCarthy) right after marrying another woman. "I was very disappointed about leaving the show, but what a way to go -- to have Jenny McCarthy make love to me in the most marvelous ways," he says with a wry smile.
