I'm fortunate that the books sell, but even more fortunate to live in Chatham, to be very happily married and to have, on the whole, a fairly clear conscience.
What I mean by that is that the point of life, as I see it, is not to write books or scale mountains or sail oceans, but to achieve happiness, and preferably an unselfish happiness.
I know nothing about producing TV drama and any involvement on my part is liable to prove an obstacle to the producers, so I prefer to be a cheerleader and let them get on with it.
I sometimes wonder what would have happened if the first book had not sold... doesn't bear thinking about, but I suppose we'd have made it work somehow.
And yes, there's a simplicity to writing books because you're not a member of a team, so you make all the decisions yourself instead of deferring to a committee.
So the books have a greater appeal to a British audience, but that hasn't stopped them making best-seller lists in places like Brazil, Japan and at least a dozen other countries.
Then you start another book and suddenly the galley proofs of the last one come in and you have to wrench your attention away from what you're writing and try to remember what you were thinking when you wrote the previous one.
