Cosmic Hobo produce the excellent and highly entertaining Scarifyers audio adventures (which you may have heard on BBC Radio), featuring occult investigators ghost-story writer Professor Dunning (Terry Molloy) and his colleague from the Metropolitan Police, Inspector Lionheart (Nicholas Courtney). The five tales (so far) have included a variety of brilliant actors, including Brian Blessed, Leslie Phillips, Nigel Havers, David Benson... and many more. The stories started out brilliant and have just got better with each new release. (If you're wondering what my involvement is, I designed and illustrated the CD inserts for the series).
They also have two other fantastic releases in the form of Peter Cushing's own reading of his autobiography (Past Forgetting) and the never-before released audio version of The Return of Sherlock Holmes, also read by the wonderful Peter Cushing. All marvellous for listening to while spending long hours at the drawing board!
