The light began to flicker, and he investigated, swearing when he found the palm oil in the lamp was almost exhausted. He started to shout for Aram, then shrugged his shoulders and blew out the light. In the soft darkness he stretched himself fully clad on the couch, his sinewy hand by instinct searching for and closing on the hilt of his broadsword. Glancing idly at the stars framed in the barred windows, with the murmur of the breeze through the palms in his ears, he sank into slumber with a vague consciousness of the muttering drum, out on the desert--the low rumble and mutter of a leather-covered drum, beaten with soft, rhythmic strokes of an open black hand.... 2 The Night Skulkers It was the stealthy opening of a door which awakened the Cimmerian. He did not awake as civilized men do, drowsy and drugged and stupid. He awoke instantly, with a clear mind, recognizing the sound that had interrupted his sleep. Lying there tensely in the dark he saw the outer door slowly open. In a widening crack of starlit sky he saw framed a great black bulk, broad, stooping shoulders and a misshapen head blocked out against the stars. Conan felt the skin crawl between his shoulders. He had bolted that door securely. How could it be opening now, save by supernatural agency? And how could a human being possess a head like that outlined against the stars? All the tales he had heard in the Zuagir tents of devils and goblins came back to bead his flesh with clammy sweat. Now the monster slid noiselessly into the room, with a crouching posture and a shambling gait; and a familiar scent assailed the Cimmerian's nostrils, but did not reassure him, since Zuagir legendry represented demons as smelling like that. Noiselessly Conan coiled his long legs under him; his naked sword was in his right hand, and when he struck it was as suddenly and murderously as a tiger lunging out of the dark. Not even a demon could have avoided that catapulting charge. His sword met and clove through flesh and bone, and something went heavily to the floor with a strangling cry. Conan crouched in the dark above it, sword dripping in his hand. Devil or beast or man, the thing was dead there on the floor. He sensed death as any wild thing senses it. He glared through the half-open door into the starlit court beyond. The gate stood open, but the court was empty. Conan shut the door but did not bolt it. Groping in the darkness he found the lamp and lighted it. There was enough oil in it to burn for a minute or so. An instant later he was bending over the figure that sprawled on the floor in a pool of blood.
