I had travelled a long distance by train to an address I had been given over an encrypted email.

I was nervous that the meeting might be some sort of trap. Leaks from inside arms verification organisations are very sensitive matters. Powerful people mind about them.

I wasn't sure whether to be afraid of being followed, or to be worried about who might be waiting behind the anonymous door on a dark afternoon, far from home. I took all the amateurish precautions that I could think of.

As it happened, it was not a trap. Now, on carefully selected neutral ground, I was to meet a person who would confirm suspicions that had been growing in my mind over several years – that there is something rotten in the way that chemical weapons inspections are being conducted and reported. And that the world could be hurried into war on the basis of such inspections.
