Charlie Higson - author of the new Doctor Who eBook ‘The Beast of Babylon’ talks about his childhood watching the First Doctor William Hartnell, and his respect for Russel T Davies and Christopher Eccleston for successfully regenerating the series.

Fittingly, ‘The Beast of Babylon’ is a Ninth Doctor adventure across three time periods, with a twist in the tale that Charlie believes could never be replicated by any other medium.
