Morse's interests
Morse had diverse passions: music (especially opera, with Wolfgang Amadeus Mozart and Richard Wagner among his favourite composers), poetry, art, the classics, British real ale, classic cars and cryptic crossword puzzles. When seen at home, Morse is usually listening to music on his Roksan Xerxes record player, solving a crossword, reading classic literature - for instance, Jude the Obscure in season 2, episode 2's Last Seen Wearing - or drinking ale. In his home, the living room had a chess set containing classical Staunton chess pieces, while the art on the walls includes etchings of Roman ruins by G.B. Piranesi from his Vedute di Roma series. While working, Morse subsists on quickly downed pints of ale (preferably real ale) in pubs, usually bought by Lewis, who struggles to keep up. Many of his cases touch on Morse's interests and often his knowledge helps him solve them.
In "The Death of the Self", the episode ends with Morse seeing one of the characters, an opera singer recovering from a long absence due to stage fright, make her "comeback" performance at the amphitheatre in Verona, while, in "Twilight of the Gods", he investigates the life of one of his opera idols, Gwladys Probert, a world-famous soprano. In "Who Killed Harry Field?", the murder victim is a painter and in "The Way Through the Woods", Morse researches the Pre-Raphaelite movement to aid his investigations.
In several episodes, Morse's crossword-solving ability helps him to spot people who have changed their identities by creating a new name using an anagram. In "Masonic Mysteries", he is maliciously implicated in the murder of a woman when his Times newspaper with the crossword puzzle completed in his handwriting is placed in the victim's house. In that same episode, the writer names Morse's old inspector from when he was a detective sergeant as "Macnutt", an homage to D.S. Macnutt, the famous and influential Observer puzzle setter 'Ximenes'.
In "The Sins of the Fathers", he investigates a murder in a brewery-owning family and, in the first episode of the series, "The Dead of Jericho", he compares the life of a dead woman with that of Jocasta, the mother of Oedipus. The same episode also introduced his Jaguar Mark 2 automobile, which is damaged at the beginning and the end of the story, being used to prevent the escape of the perpetrators. His interest in classic cars is also explored in "Driven to Distraction", in which he suspects a car salesman of murder. He seems to dislike Jeremy Boynton so strongly that, when he refers to Morse's own Jaguar as "she", this convinces Morse of his guilt.
In "Cherubim and Seraphim", he investigates the suicide of his niece and discusses with her English teacher her interest in the poet Sylvia Plath, who also killed herself. The teacher defends the teaching of Plath's poetry to students, saying that her suicide would not influence students to do the same. Investigating the killing of a retired detective in "Second Time Around", Morse is haunted by an early case of his in which a young girl had been murdered and an obvious suspect could have very well been innocent.
