Somehow addressing the young man as Mr Lloyd didn't seem appropriate, and first names were completely out of the question- assumed familiarity was not something that would go down well, especially if the boy was in fact sent by the Morning Chronicle. Such things were not unheard of.
"Master Lloyd," That was better than nothing, "I appriciate the time and effort you have taken to come here this evening. But regardless of what some city news-sheets are reporting, there is no monster in London, nor any particularly intelligent beasts planning vicious attacks. I will order a cab, but it will be delivering you to your door."
