One hoped that the poisoning of the two Russians in Salisbury and thankfully their recovery, would have meant no further poisonings, but no, as we all know by now.
It appears that Charlie Rowley found the bottle containing Novichok and, thinking it was expensive perfume, gave it to his partner Dawn Sturgess, who sprayed it on herself, immediately fell ill and tragically died some days later.
The nerve agent seems to have affected his memory, he can't remember where he actually found the bottle and the experience has clearly shaken him to the core.
