dire straits private investigations

It s a mystery to me The game commences For the usual fee Plus expenses Confidential information It s in a diary This is my investigation It s not a public inquiry I go checking out the reports Digging up the dirt You get to meet all sorts In this line of work Treachery and treason There s always an excuse for it And when I find the reason I still can t get used to it (C) Mark Knopfler
