This reminds me of a mash-up of Guys & Dolls (the movie) and Sunday School at a particularly gloomy church. It's the whole of the Comedy: Hell, Purgatory, and Heaven. All the characters look straight out of the 40s and 50s. Very odd.
I guess it's good that I read this, since I've never made it past Hell in the actual printed version. Now I can say I know how it all ends. ;-)
