1All at once one of the detectives at the window gave a short, sharp gasp. The others looked at him, and then quickly followed his own gaze upward to the point at which its idle straying had been suddenly arrested. There was no need for words. What had been disputed in country gossip was disputable no longer, and it is because of the thing which every man of that party agreed in whispering later on, that strange days are never talked about in Arkham. It is necessary to premise that there was no wind at that hour of the evening. One did arise not long afterward, but there was absolutely none then. Even the dry tips of the lingering hedge-mustard, grey and blighted, and the fringe on the roof of the standing democrat-wagon were unstirred. And yet amid that tense, godless calm the high bare boughs of all the trees in the yard were moving. They were twitching morbidly and spasmodically, clawing in convulsive and epileptic madness at the moonlit clouds; scratching impotently in the noxious air as if jerked by some allied and bodiless line of linkage with sub-terrene horrors writhing and struggling below the black roots.

2Not a man breathed for several seconds. Then a cloud of darker depth passed over the moon, and the silhouette of clutching branches faded out momentarily. At this there was a general cry; muffled with awe, but husky and almost identical from every throat. For the terror had not faded with the silhouette, and in a fearsome instant of deeper darkness the watchers saw wriggling at the treetop height a thousand tiny points of faint and unhallowed radiance, tipping each bough like the fire of St. Elmo or the flames that come down on the apostles' heads at Pentecost. It was a monstrous constellation of unnatural light, like a glutted swarm of corpse-fed fireflies dancing hellish sarabands over an accursed marsh; and its colour was that same nameless intrusion which Ammi had come to recognise and dread. All the while the shaft of phosphorescence from the well was getting brighter and brighter, bringing to the minds of the huddled men, a sense of doom and abnormality which far outraced any image their conscious minds could form. It was no longer shining out; it was pouring out; and as the shapeless stream of unplaceable colour left the well it seemed to flow directly into the sky.
