It's much harder to be self critical. I fail to spot my own gaffes. I suppose I read what I expect to be there, because I wrote it.The Writers' Forum magazine has a 'First Draft' section every month where readers are invited to deliberately input 20 errors into the work of a published writer. It's an interesting exercise and a bit of fun too. In Issue #161, March 2015 you will find my ruination of an excerpt from 'The Woman Who Died a Lot' by the great Jasper Fforde. To whom I offer my humblest apologies.
