Guilty ?

Her face bears witness to a chequered history I suspect.

I don't know anything about her.  I went for a walk to enjoy the sunshine and as I returned past the old churchyard, there was a very spattered and half-eaten bluetit on the pavement.  It hadn't been there when I set off.

I glanced over the wall and saw her, looking a bit guilty and certainly suspicious.

It's a hard life.
