"I trust you’ll understand the reference to/Another Scottish tragedy without my having to name the play."
"They think me Macbeth and ambition my folly."
Macbeth, tragedy in five acts by William Shakespeare, written sometime in 1606–07 and published in the First Folio of 1623 from a playbook or a transcript of one. Some portions of the original text are corrupted or missing from the published edition. The play is the shortest of Shakespeare’s tragedies, without diversions or subplots. It chronicles Macbeth’s seizing of power and subsequent destruction, both his rise and his fall the result of blind ambition.
In theater communities, the curse of Macbeth brings bad luck to any theater or production where someone says the play or character's name inside the theater, except within the context of a performance. To avoid invoking the curse, theater professionals will often refer to Macbeth as the "Scottish Play." Source
