I know what it feels like to be in a shoot-out, what the discharge of weapons looks like, sounds like, smells like. As a novelist, I used it in my third book, Into the Fire. But, using bad experiences as material does not exorcise them. I know about fear, and I wish I didn't. It does not disappear, it just creeps into hiding somewhere in our beleaguered bodies. I know how corrosive it is, how it taints your life, steals your freedoms. There is no safe hiding place from either criminals or fear. We have to attack crime, catch and punish the criminals, not insulate ourselves behind high walls and barbed wire. Six weeks on, my sudden crying jags have stopped. Now I just feel angry. I, for one, refuse to accept that if you live in London, crime is the price you pay.
