“The Riddle” is a song by the English singer-songwriter Nik Kershaw. It was released in 1984 as the lead single from the album of the same name. Kershaw described the lyrical content as being nondescript to fill as a “guide vocal” for the production. It reached number three on the UK Singles Chart and peaked within the top 10 in countries like Ireland, Norway, Sweden, Australia and New Zealand. An accompanying music video was made for the song and features references to Lewis Carroll’s book Alice in Wonderland. The song was covered by many artists, most notably by Gigi D’Agostino (2000) and Jack Holiday and Mike Candys (2012).
