Robertson was bigger than me, but soft. Had his anger been that of an ordinary man, perhaps pumped up by one beer too many, I might have confronted him and would have been confident of taking him down. He was a lunatic, however, an object of fascination to bodachs, and an idolizer of mass murderers and serial killers. I had to assume that he carried a gun, a knife, and that in the middle of a fight, he might begin to bite like a dog.
