I enjoyed this podcast while standing in JFK airport, waiting for my luggage. A bit of Gotham there, I suppose. I'm not a comic book reader much anymore, though I was in the late 70's to early 90's, but never a Batman reader.
I read this collection from my library's e-book collection. It was certainly a fun investigation into Gotham's deep past that pre-dates Batman, and a reminder that none of us know a place as well as we think we do.
Minor Spoiler Alert!
One question: if Dick's in Arkham, disguised as Joker to get info, where's the real Joker?
