As a dancer she's undercover
  Won the Big Don to be her lover
  Had to make him tell her his secrets
  About his business and about his street-rats
  She had to become his trustful right hand
  The burean needed the files with his brand
  She really was a damn good actress
  Everybody called her 'Big Don's Mistress'
  
  Oh, it's just a show
  Put on for love
  How could he know
  Liar, liar
  Sweet desire
  Liar, liar
  Who are you
  Liar, liar
  Play with fire
  Liar, liar
  Learn the truth
  
  She sent the messages to her office
  The Don reckoned he will face a judas
  So he told her of a damned deceiver
  Secured, in her he was a strong believer
  He confessed to her being sick of all this
  How he suffered in the deepest abyss
  But saw in her the wish for a new life
  To escape from there and wake her his wife
  
  No, not just a show
  Put on for love
  How could he know
  Liar, liar
  Sweet desire
  Liar, liar
  Who are you
  Liar, liar
  Play with fire
  Liar, liar
  Learn the truth
  
  It had turned somehow
  She had not seen how
  Felt the bullet still flying
  Straight into her heart
  Tore her old world apart
  Now to live on she first had to die
  There's a reason to live
  Now to live on she first had to die
  There's a reason to give
  There's a reason to give in a lie
  
  Liar, liar
  Sweet desire
  Liar, liar
  Who are you
  Liar, liar
  Play with fire
  Liar, liar
  You learned your truth now
