plot thickens, the

The situation is becoming increasingly complex. Originally the term was used to describe the plot of a play that was becoming byzantine in its complexity; it was so used by George Villiers in his 1672 comedy The Rehearsal (3.2). It was repeated by numerous writers and became particularly popular in mystery novels, from Arthur Conan Doyle’s A Study in Scarlet (1887) on. Today it is often used sarcastically or ironically of some situation that is needlessly complex but scarcely meets the description of a sinister plot.
