Smouldering

I left Holmes seated in front of the smouldering fire, and long into the watches of the night I heard the low, melancholy wailings of his violin, and knew that he was still pondering over the strange problem which he had set himself to unravel.

A hound it was, an enormous coal-black hound, but not such a hound as mortal eyes have ever seen. Fire burst from its open mouth, its eyes glowed with a smouldering glare, its muzzle and hackles and dewlap were outlined in flickering flame.

When now the Gods have made proud Ilion fall, / and Asia's power and Priam's race renowned / o'erwhelmed in ruin undeserved, and all / Neptunian Troy lies smouldering on the ground, / in desert lands, to diverse exile bound, / celestial portents bid us forth to fare; / where Ida's heights above Antandros frowned, / a fleet we build, and gather crews, unware / which way the Fates will lead, what home is ours and where.

I didn't see him. I saw just a smouldering cigarette that he had left before.
