But, instead, I am here. I made my choice and I have no choice now; I must stick with it. I worked out my route, set up the means and the funding and the personnel with the required skills to aid me on my way into obscurity and unfindability, tested the ways those who might want to find me might set about doing so and worked out methods of frustrating their quest, then – with everything in place – went through with it.

So, thinking, here I lie.

Others have told me that for them it happens during a blink, or just at random between heartbeats or even during a heartbeat. There is always some external sign: a shiver or tremble, often a noticeable twitch, occasionally a jerk, as though an electric shock has passed through the subject’s body. One person said that the way it happens for them is that they always think they’ve just caught a glimpse of something surprising or threatening from the corner of their eye and – as they turn their head quickly round – experience a distressing burning sensation like a sort of internal electric shock buzzing through the neck. For me it is usually fractionally more embarrassing; I sneeze.

I just sneezed.

I have only the vaguest idea how long I sat outside that little café in the 3rd, waiting for the drug to take effect, sinking into the waking dream that is the necessary precursor to navigating accurately to our desired destination. A few seconds? Five minutes? I trust I paid my bill. I should not care – I am not him, and anyway he will still be there – but I do care. I sit forward, look at the table in front of me. There is a small pile of change sitting on the little plastic tray with the bill clipped to it. Francs, centimes; not euros. So; so far, so good.
