Okay, Penny Dreadful—-if you hadn't already had me sold with your concept, you would have won me over by using this phrase last night. Also the word "peripatetic".
It is such a joy for a book-addicted, vocabulary nerd like myself to hear things like this spoken in dialogue. ON TV.
Thank you, current television people, for creating shows that assume your viewers are intelligent people that don't need things spoon-fed to them.
