Yes, back at the British Library contemplating life with Isaac Newton after three years of the good, the bad and the downright awful. Illness and operations, death of close friends, love, family, friendships lost and gained, writing successful and failed and soles worn through by bushwalking. It has been three years of turmoil in which the good outweighs the bad and best of all, I’m here to tell the tale. Three years older and possibly, just possibly, at long last a little wiser. Probably not.

Last time Isaac and I contemplated life together, I was on my way to do the Coast to Coast walk across England [with two broken bones in my foot though I didn’t know that at the time]. This time it is Scotland, the West Highland Way and the Great Glen Way taking me from Glasgow to Inverness. And maybe somewhere beyond that, we shall see.

For now, the path beckons. This one is from the Larapinta Trail in central Australia a few weeks ago – trust me, there is a track in this beautiful solitude. There is always a path if we but look.
