much as ever at a loss to find the ruling clew in this maze of strange evidence. For three days the bad weather lasted, changing from driving rain to a dense mist, fine and dripping, and we seemed to be shut up in a white cloud that veiled all the world away from us. All the while Professor Gregg was darkling in his room, unwilling, it appeared, to dispense confidences or talk of any kind, and I heard him walking to and fro with a quick, impatient step, as if he were in some way wearied of inaction. The fourth morning was fine, and at breakfast the professor said briskly:—
"We want some extra help about the house; a boy of fifteen or sixteen, you know. There are a lot of little odd jobs that take up the maids' time, which a boy could do much better."
"The girls have not complained to me in any way," I replied. "Indeed, Anne said there was much less work than in London, owing to there being so little dust."
"Ah, yes, they are very good girls. But I think we shall do much better with a boy. In fact, that is what has been bothering me for the last two days."
"Bothering you?" I said in astonishment, for as a matter of fact the professor never took the slightest interest in the affairs of the house.
"Yes," he said, "the weather, you know. I really couldn't go out in that Scotch mist; I don't know the country very well, and I should have lost my way. But I am going to get the boy this morning."
"But how do you know there is such a boy as you want anywhere about?"
