Falling Darkness

I know I said I would post about Saturday, but I didn't. I'd do it now, but I only have a few minutes.
Last night I watched Falling Darkness, an Inspector Lewis Mystery. Here's the trailer.

Now, if you actually want to watch it, go here: http://www.pbs.org/wgbh/masterpiece/lewis/watch.html BEFORE OCTOBER 26th.
Now, since I feel like it, can you guess who all these British actresses are?

 Who plays Stallwood and Hobson?

I wonder sometimes why most police-women in PBS Mystery shows are small and blonde.  Even Barbara Havers is blonde-ish.
