On the Razzle is a play by Tom Stoppard.
 It is an adaptation of the Viennese play "Einen Jux will er sich machen" by Johann Nestroy, which had been adapted twice by Thornton Wilder.
 The first 1938 version, entitled "The Merchant of Yonkers", was faithful to the original material, but the second 1955 version, renamed "The Matchmaker", expanded the previously secondary role of Dolly Gallagher Levi, who later became the heroine of the Jerry Herman musical hit, "Hello, Dolly!
".
 Stoppard's adaptation eliminates the Dolly character.
Dogg's Hamlet, Cahoot's Macbeth are two plays by Tom Stoppard, written to be performed together.
 This was not the first time that Stoppard had made use of Shakespearian texts in his own plays or even the first time he had used "Hamlet" although the context is far different from that of his earlier "Rosencrantz and Guildenstern are Dead".
 Stoppard would return to the theme of artistic dissent against the Communist Party of Czechoslovakia in "Rock 'n' Roll".
Rosencrantz and Guildenstern Are Dead, often referred to as just Rosencrantz and Guildenstern, is an absurdist, existentialist tragicomedy by Tom Stoppard, first staged at the Edinburgh Festival Fringe in 1966.
 The play expands upon the exploits of two minor characters from Shakespeare's "Hamlet", the courtiers Rosencrantz and Guildenstern.
 The action of Stoppard's play takes place mainly "in the wings" of Shakespeare's, with brief appearances of major characters from "Hamlet" who enact fragments of the original's scenes.
 Between these episodes the two protagonists voice their confusion at the progress of events occurring onstage without them in "Hamlet", of which they have no direct knowledge.
The Quincunx (The Inheritance of John Huffam) is the epic first novel of Charles Palliser.
 It takes the form of a Dickensian mystery set in early 19th century England, but Palliser has added the modern attributes of an ambiguous plot and unreliable narrators.
 Many of the puzzles that are apparently solved in the story have an alternative solution in the subtext.

 His most well-known novel, "The Quincunx", has sold over a million copies internationally.
