The setting of the titular House was my favourite thing about this story – I love weird, constructed little societies like this. It's quite a satisfying mystery, with setup and payoff neatly intertwined. Also, if I had a nickel for each time a Doctor Who story takes place in a massive creepy house made out of the flesh and bone and enamel of a single person I'd have two nickels, which isn't much but it's weird it happened twice etc...

I surprised myself by how much I liked the character of Frances. I love that weird, anxious, upper-class lesbian. And who wouldn't fall in love with Lucie Miller?
