Conspiracies or Imagination?

“You don’t understand how big this thing is.”

Jack Ruby

“Theatre is where people rehearse justice.”

Dorothy Kilgallen

Torben Betts has given his new play an honest title.  Speculations introduces conspiracy theories around the deaths of Marilyn Monroe and John F Kennedy.  They are linked together by the investigative journalism of New Yorker and theatre critic Dorothy Kilgallen, played by Janie Dee, who explains her work to African American visitor Flo (Gloria Obianyo) who has been hired to look after Dorothy’s son.

Lee Newby’s set of a grand New York apartment living room with desk  for Kilgallen divides and rotates efficiently to the Los Angeles Brentwood bedroom where Marilyn Monroe (Natalie Dunne) meets Robert Kennedy (Jolyon Coy) and to the dimly lit New Orleans bar where mobster Carlos Marcello (Ferdy Roberts) is recruiting Lee Harvey Oswald (Joseph Potter).

Quite scarily, Dorothy Kilgallen is nervous that she might now be a target for those involved in the conspiracies that she is researching.  She has been to Texas and interviewed the man who assassinated Lee Harvey Oswald in Dallas, Jack Ruby.  Marilyn had died in the summer of 1962, JFK was shot in Dallas in November 1963. 

The first flashback is to Brentwood and a scene between Robert Kennedy and Marilyn Monroe discussing a threat she has made to reveal a bombshell the next week to the press.  Robert Kennedy is searching her home for her diary which he thinks will have a record of when she met him and JFK and discussion about JFK’s plot against Fidel Castro. The issue for us is whether she committed suicide or that she took an accidental overdose or whether she was murdered by the administration of drugs and a fatal enema.

The scenes in the New Orleans bar have Carlos Marcello explaining the motives the Mafia have for getting rid of the President JFK.  Marcello says Lyndon B Johnson is “one of theirs”.  We hear about Oswald’s background, his time in the Marines, his qualification as a sharpshooter and his time in Russia and his Russian wife and child.  Marcello says that there are several shooters to be placed around the presidential route and that the Book Depository where Oswald has a job is one of them. 

Trevor Nunn’s experience directing is unquestionable and the performances are good although Ferdy Roberts’ Mobster is a tad melodramatic.  Janie Dee’s acts frame the scenes elsewhere convincingly and we are all interested that Dorothy rose to fame as a theatre critic!

The play draws you into the conspiracies none of which are new revelations but the structure of the play works well at introducing the theoretical basis.  I saw The Marilyn Conspiracy at The Park Theatre in June 2024 which just concentrated on the death of Marilyn Monroe and actually find it quite sad that more is written about her death than her beauty and skill as a talented actress but then that is the draw of conspiracy theories.  I was diverted By Torben Betts’ play if not newly informed.
