It occurred to me that this whispering was different from anything else of the kind I had ever heard; that, despite the curious motionlessness of the speaker’s moustache-screened lips, it had a latent strength and carrying-power remarkable for the wheezing of an asthmatic. I had been able to understand the speaker when wholly across the room, and once or twice it had seemed to me that the faint but penetrant sounds represented not so much weakness as deliberate repression—for what reason I could not guess. From the first I had felt a disturbing quality in their timbre. Now, when I tried to weigh the matter, I thought I could trace this impression to a kind of subconscious familiarity like that which had made Noyes’s voice so hazily ominous. But when or where I had encountered the thing it hinted at, was more than I could tell.
