Vimes, in the privacy of his own head, tried out the statement, ‘Well, since you ask, I have a deadly demon sharing my mind, which seems to be helping me for reasons of its own. It lets me see in this gloom and somehow allows me and goblins to communicate. It’s called the Summoning Dark. I don’t know what its interest in goblins is but the dwarfs think it brings down wrath on the unrighteous. If there has been a murder I’ll use any help I can get.’ He did not in fact articulate this, on the basis that most people would have left very quickly by the time he had finished, so he settled for saying, ‘I have the support of a higher power, chief constable. Now, let’s check out this place.’ This didn’t satisfy Feeney, but he appeared to understand that it was all he was going to get.
