Robert Cowan, in his professional life, would have examined and determined the origins and make-up of thousands of substances, black white and brindle.
Hundreds of thousands, either personally or by delegation, and everything noted and filed. No sense in doing anything twice.
Yet in this instance Cowan was completely dumbfounded, and admitted he was unable to identify a black powder shaken from a cheap brush found in the deceased’s suitcase. A brush that appeared to be part of a crudely made set of tools (kitchen knife and scissors) found in the same bag.
