Taking A Fall For The Second Time

David Blunkett has resigned for the second and probably final time. Politicians generally have just one professional life, how many do writers have? Is it possible to have literary success followed by a fallow period, being dropped by your publisher, your agent... And then make a startling comeback with a piece of writing so amazingly accomplished that soon critics are saying it is your "best thing since...", effectively joining up your 'old' writing life and your newfound one. Will that happen to me one day, I wonder?
