I am certain that you're remembering one of my favorite thrillers,
Lawrence Kasdan's "Body Heat," starring Kathleen Turner, William Hurt,
and Richard Crenna. Below I've gathered some brief excerpts from
online descriptions of the plot so that you can verify that this is
the correct movie.
"Ned Racine (Hurt) is a thirty something lawyer working the seedy side
of the street in Miranda Beach, Florida... It's Matty who insinuates
the problem, then suggests the solution even though Ned thinks the
solution is his. While the death-fight with Edmund Walker in the hall
of his opulent home is a fitting parody of Ned's first sex with Matty,
the disposal of his body by arson bomb in the abandoned beachfront
club The Breakers is sublime. The method is crude, yet the desired
insinuation is that Walker died as part of an on-going real-estate
scam engineered by the shadowy criminal investors with whom he's
associated... The criminal rewriting of Edmund Walker's will requires
an expert, of course, but also one who might make the mistake
essential for Matty's plan to be fully realized... Part of the will
deposition is the 'missing witness' factor, which also figures
significantly in the action and the crunching ironies of the ending."

"Matty Walker (Turner)... despite being married lures the panting
local, small-town Miranda Beach, Florida, screw up lawyer, a seedy but
slick looking bachelor in his thirties who thrives on being a
womanizer, Ned Racine (Hurt). After about a month of this torrid
affair, she moves in for the kill and gets... Ned to murder her
husband in what is supposed to be the 'perfect crime.' Whereby he
kills him in his luxurious Pinehaven house in a gruesome manner and
then dumps his body in a abandoned beachfront club called The
Breakers, that's torched and the crime is made to look like his
scheming real-estate partners might be involved. He does this all in
the name of greed and lust, as his expectation is of them living
happily together ever after on the inheritance she will collect... Ned
first realizes something is wrong and he might be setup to be betrayed
by his partner, when the 'will' he slightly revised in secret for her
husband is considered invalid because of a technicality over a witness
who can't be located."

"The plot is simple, yet ingenious. In steamy, hot, and sultry coastal
Florida, a beautiful blonde, unhappily married socialite, Matty Walker
(Kathleen Turner), a veritable man trap with her smoky voice and Venus
de Milo curves, meets a womanizing chump, Ned Racine (William Hurt), a
small town, not too successful lawyer... Matty is married to a
rapacious business man, Edmund Walker (Richard Crenna), whom Matty
wants to have permanently removed... As Matty slowly spins her web and
ensnares Ned, like a mouse in a trap, he falls into lock step with
Matty's homicidal plans. What he does not initially realize is the
extent of Matty's perfidy and deceit, until it is too late. As the
realization of what actually has happened begins slowly to dawn upon
Ned, it is a thing of on screen beauty and an absolutely brilliant
contrivance with which to push the film further along to its ultimate
resolution. What initially appears to be just a film about sexual
obsession turns out to be something quite different, with enough plot
twists to keep the viewer riveted to the screen."
