I'm deeply sorry I missed the info, but William Franklyn has passed away at the end of october from a prostate cancer. As the BBC says "His 50-year career encompassed TV, radio, film and stage, appearing in episodes of The Avengers and The Scarlet Pimpernel among many others. He also appeared in television shows such as Top Secret, Splitting Heirs and Ooh, You Are Awful".
He will be best remembered by us of couse for his work on the new Hitchhiker's radio series. He was the voice of the book in the Tertiary, Quandary and Quintessential phases. He replaced his old friend Peter Jones who was of course the legendary voice of the book in the original radio series and in the BBC TV series.
