"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 song begins with a deep-pitched synthesizer orchestration (omitted from the 7" single edit), leading into a slow piano progression accompanying a classical guitar, followed by several spoken verses. The single edit removes the opening synthesisers, beginning with acoustic guitar.
After the verses, the song opens into a slow, bass-driven beat, with strident electric guitar chords at the end, before the gradual diminuendo featuring extended interplay between Mark Knopfler's acoustic guitar and marimba played by Mike Mainieri.
The cache is hidden slightly off the path, at the base of a tree. It is a small tupperware box, with room for swaps.
