Madame Vastra Investigates

So my main thought from the latest episode of Doctor Who was: "Why do these two not have their own show???"

Actually, my main thought at the time was asdfghjkl;, but you know what I mean.

Seriously though, a katana wielding Silurian lady living in Victorian London, solving crime (and occasionally eating criminals) with the help of her human maid/lesbian lover?
YES PLEASE.

Silly title I know, but I'm not great at thinking up names for stuff. I'll take suggestions though!

P.S. It occurs to me that I should put a spoiler warning on this, as the episode hasn't aired in the US yet. But honestly, it's not an important plot point or anything. Also, if you haven't found a way to somehow illegally watch it anyway, you clearly don't care enough to worry about being spoiled.
