1) I see the term 'underground' being thrown around a lot around, I notice that you seem to use it quite frequently yourself. What does this term mean to you? Is it simply a marketing term or is there some real meaning to it, is it a genre of magic, or a way of looking at magic etc?. 2) I notice that in Collateral you refer to it as being the last book of it's kind (I can't remember the exact wording right now), does this reflect a change in your perceptions or approach to magic? 3) What's your approach to hecklers? It appears in Dangerous you have a fairly laid back style, how would you try and control somebody who is trying to cause trouble and disrupt your performance? Are there any steps you take to prevent this from happening? Also, what do you think motivates somebody to be a heckler?
