"Private Investigations" is a song by the British rock band Dire Straits from their album Love over Gold. It reached number 2 in the United Kingdom (despite its length), and is one of their biggest chart successes in the UK. The track has appeared on the compilation albums Money for Nothing and Sultans of Swing: The Very Best of Dire Straits, and is the title track to the more recent 2005 compilation, Private Investigations: The Best of Dire Straits & Mark Knopfler. The riff from the song was used in France on a Crédit Agricole advert in 1984, and on a BT advert in 1994.
