Fear

Another story from the anthology: Algernon Blackwood's The Empty House:

Inside the house the silence became awful; awful, he thought, because any minute now it might be broken by sounds portending terror. The strain of waiting told more and more severely on the nerves; they talked in whispers when they talked at all, for their voices aloud sounded queer and unnatural. A chilliness, not altogether due to the night air, invaded the room, and made them cold. The influences against them, whatever these might be, were slowly robbing them of self-confidence, and the power of decisive action; their forces were on the wane, and the possibility of real fear took on a new and terrible meaning. He began to tremble for the elderly woman by his side, whose pluck could hardly save her beyond a certain extent.

Anyone who says there's not enough time in a short story to build suspense has never read this.
