Is this spam? If so, why?

Both why is it spam, and why have they sent it to me?

Dear, I no longer want to live in lies. Can you give me a favour ?

Is this a cunning attempt to work out whether my email address is genuine, by waiting to see if they get a reply from me along the lines of "What the hell are you on about?" If not, what is the point?

It's totally bizarre: it has all the hallmarks of spam (free throwaway email account, none of the standard email client headers), but none of the obvious evil. Yet.
