. . . is the question in this not-too-serious murder-mystery, almost a send-up of 1940s and 1950s-era who-done-it films and James Cain detective novels.

A young housekeeper/slash aspiring journalist ends up dead in the hotel room of a famous television duo, along the lines of Jerry Lewis and Dean Martin, played by Kevin Bacon and Colin Firth. Was she a suicide, or the unfortunate murder victim of a menagerie-a-trois gone wrong?

Another aspiring journalist, played by Alison Lohman, spends the rest of the film-- now set 15 years later, in the early 1970s when the fame of the duo is on the wane --trying to find out.

There is female nudity galore throughout this movie-- Alison Lohman (topside and backside), Kristin Adams (topside), Rebecca Davis (everything), and Rachel Blanchard (everything). Blanchard, up until this point, was probably most famous as the child actor who played the daughter of an Earth resistance scientist in the 1988 - 1990 TV series War of the Worlds (sequel to the 1953 movie).

In the interest of balance, I should mention that Bacon is also nude in this film, showing mostly backside, but even some of little Bacon makes a brief appearance. I gotta say, Kevin Bacon was around 47 years old when he played this part, frolicking around with women who were in their 20s-- but my, was this man in shape, more so than a great many men half his age.

Since the director of Where the Truth Lies also directed the previous Exotica (1994), one must wonder if Atom Egoyan could be considered the don of Canadian erotic cinema (a very shallow pool of films, but existent nonetheless; who would've thought?)

Where the Truth Lies (2005)-- more of a sex romp than a serious murder-mystery, whatever the stated intentions of the director might have been.
