Dear Chris,

As best as I can tell. He is the best expert in Britain on Chemical weapons. I did some organo phosphate chemistry (peacefully) because it can be made to make new medicines safely & efficiently. I know the poor man lost is wife under very difficult circumstances. He is exceptinally more talented than me. He can explain Novichok. I hope you don't need to consult him. He certainly must be one of the top 10 in the world if you are ever between a "rock & a hard place"
