I am genuinely shocked and saddened by today's news that we have lost Sir Terry Pratchett. He died at the age of 66, losing the battle against Altzheimer's disease; something he described when first diagnosed as "an embuggerance". I bought my first Discworld book the year it was first published, and have relished every one since. His wicked sense of humour and cast of grotesques, warewolves, vampires, trolls, wizards, witches, conmen, patricians and ingenues have made me laugh for decades. The irony of being claimed by Death - one of his most popular characters - will not have been lost on Sir Terry. In fact, in his own words: "'DON’T THINK OF IT AS DYING’, said Death. ‘JUST THINK OF IT AS LEAVING EARLY TO AVOID THE RUSH'" Adieu, Sir Terry.
