Neverwhere by Neil Gaiman has been a TV show, a novel, a comic, a radio play, a stage play, and I wouldn't be surprised if it has been a puppet show in some form or other. It's immensely popular for a number of excellent reasons including a mythologized cityscape of London and a host of bizarre and fascinating characters, though fans may disagree about which medium does the story the most justice. But, as has happened a couple times in the past, you can now listen to the acclaimed radio play for free for a few days, internationally online, even though it's being hosted by the BBC.
BBC Radio 4 are playing its six episodes over six nights that started on Christmas day with a 60 minute episode and will continue in 30 minute episodes thereafter through Monday the 30th airing at 11:30PM GMT, which makes for a more convenient listen in other time zones really. Also, if you missed the first one, don't despair: each episode is available for 7 days after it airs. But keep an eye on the calendar to avoid disappointment.
Dirk Maggs is the director of the radio drama, Heather Larmour is the producer, and the star-studded cast includes Benedict Cumberbatch, who plays The Angel Islington, Christopher Lee, James McAvoy, Richard Mayhew, David Harewood, Natalie Dormer as Door, Sophie Okonedo, Anthony Head, Johnny Vegas, Bernard Cribbins, and Neil Gaiman himself playing a part.
