The chords are simple:  
C        F    C    G 
 
C                  F            C 
      Darkness falls and she 
      G                  C 
Will take me by the hand 
 
Take me to some twilght land 

Where all but love is gray 

And I can't find my way 

Without her as my guide 
 

F                    G                     F 
Night falls, I'm cast beneath her spell 
                         G                        C 
Daylight comes, our heaven turns to hell 
 

      F         C              G 
Am I left to burn and burn eternally 

She's a mystery to me 
 
She's a mystery girl 

A mystery girl 

She's a mystery girl 

A mystery girl 
 
And in the night of love 

Words tangled in her hair 

Words soon to disappear 

A love so sharp it cuts 

Like a switchblade through my heart 

Words tearing me apart 
 

F             G                              F 
She tears against my bleeding heart 
                         G                        C 
Try to run but she's pulling me apart 
 
Fallin angel cries 
And I just melt away 
She's a mystery to me 
 
She's a mystery girl 
A mystery girl 
She's a mystery girl 
Sheeeeeeeeeeeeee's  a mystery girl 
 
Wanted by her side 
It's the darkness in her eyes 
That so inslaves me 
And if my love is blind 
Then I don't want to see 
She's a mystery to me 
 
Night falls, I'm cast beneath her spell 
Daylight comes, our heaven turns to hell 
 
Am I left to burn 
And burn eternally 
She's a mystery to me 
 
She's a mystery girl 
A mystery girl 
She's a mystery girl 
A mystery girl
