Dire Straits - Private Investigations

It's a mystery to me - the game commences 
For the usual fee - plus expenses 
Confidential information - is 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 
And what have you got at the end of the day? 
What have you got to take away? 
A bottle of whisky and a new set of lies 
Blinds on the windows and a pain behind the eyes 
Scarred for life - nocompensation
