What is the theme in Dogg's Hamlet, Cahoot's Macbeth by Tom Stoppard?

Censorship is another theme in the play. In Cahoot's Macbeth, the ability to communicate in Dogg eventually becomes a tool for fighting censorship. The play is set in a woman's living room—a supposedly nonpublic location where the actors can perform their plays, without having to worry about being arrested. However, while the actors are performing their abbreviated version of Macbeth, a police inspector arrives and looks for reasons to arrest the actors and hostess. He walks around the room, saying, "Testing, testing—one, two, three . . . ," which is, as Stoppard notes in the stage directions, an obvious sign that "the room is bugged for sound."
