TLC is the latest network turning the lens on Princess Diana.

The Discovery-owned cable network has set a three-hour telecast that will examine her life and legacy, as well as conspiracy theories surrounding her tragic death in 1997 at age 36.

Premiering Monday, July 31 at 8 p.m. ET/PT, Princess Diana: Tragedy or Treason? will boast new details about Princess Diana's challenging life as a royal with Prince Charles and life as a protective mother to sons Prince William and Prince Harry. The special will include exclusive footage, excerpts from Princess Diana's interviews from biographer Andrew Morton's books and new insights into the conspiracy theories.

In addition to Morton, the three-hour special will include interviews with friends Mary Robertson and James Colthurst; bodyguard Ken Wharfe; royal biographer Ingrid Seward; royal historian Kate Williams; journalists Tamron Hall and Deborah Norville; and conspiracy theorist author and Law & Order: Special Victims Unit alum Richard Belzer.

Jupiter Entertainment and American Media, Inc. will produce for TLC.

TLC is one of several networks taking a closer look at Princess Diana ahead of the 20th anniversary of her death on Aug. 31. ABC, NBC and CBS all broadcast primetime news specials in May, and ABC is teaming with People magazine for a second, two-night documentary event set to air in August. In addition, the second season of Ryan Murphy's FX anthology Feud will center on the relationship between Princess Diana and Prince Charles.
