Behind him Griswell stifled a cry, for he had seen what prompted Buckner's exclamation. A few feet from the head of the stair Branner's footprints stopped abruptly, then returned, treading almost in the other tracks. And where the trail halted there was a great splash of blood on the dusty floor--and other tracks met it--tracks of bare feet, narrow but with splayed toes. They too receded in a second line from the spot.
Buckner bent over them, swearing.
"The tracks meet! And where they meet there's blood and brains on the floor! Branner must have been killed on that spot--with a blow from a hatchet. Bare feet coming out of the darkness to meet shod feet--then both turned away again; the shod feet went downstairs, the bare feet went back down the hall."
He directed his light down the hall. The footprints faded into darkness, beyond the reach of the beam. On either hand the closed doors of chambers were cryptic portals of mystery.
"Suppose your crazy tale was true," Buckner muttered, half to himself. "These aren't your tracks. They look like a woman's. Suppose somebody did whistle, and Branner went upstairs to investigate. Suppose somebody met him here in the dark and split his head. The signs and tracks would have been, in that case, just as they really are. But if that's so, why isn't Branner lyin' here where he was killed? Could he have lived long enough to take the hatchet away from whoever killed him, and stagger downstairs with it?"
"No, no!" Recollection gagged Griswell. "I saw him on the stair. He was dead. No man could live a minute after receiving such a wound."
"I believe it," muttered Buckner. "But--it's madness! Or else it's too clever--yet, what sane man would think up and work out such an elaborate and utterly insane plan to escape punishment for murder, when a simple plea of self-defense would have been so much more effective? No court would recognize that story. Well, let's follow these other tracks. They lead down the hall--here, what's this?"
With an icy clutch at his soul, Griswell saw the light was beginning to grow dim.
"This battery is new," muttered Buckner, and for the first time Griswell caught an edge of fear in his voice. "Come on--out of here quick!"
The light had faded to a faint red glow. The darkness seemed straining into them, creeping with black cat-feet. Buckner retreated, pushing Griswell stumbling behind him as he walked backward, pistol cocked and lifted, down the dark hall. In the growing darkness Griswell heard what sounded like the stealthy opening of a door. And suddenly the blackness about them was vibrant with menace. Griswell knew Buckner sensed it as well as he, for the sheriff 's hard body was tense and taut as a stalking panther's.
But without haste he worked his way to the stair and backed down it, Griswell preceding him, and fighting the panic that urged him to scream and burst into mad flight. A ghastly thought brought icy sweat out on his flesh. Suppose the dead man were creeping up the stair behind them in the dark, face frozen in the death-grin, blood-caked hatchet lifted to strike?
This possibility so overpowered him that he was scarcely aware when his feet struck the level of the lower hallway, and he was only then aware that the light had grown brighter as they descended, until it now gleamed with its full power--but when Buckner turned it back up the stairway, it failed to illuminate the darkness that hung like a tangible fog at the head of the stair.
"The damn thing was conjured," muttered Buckner. "Nothin' else. It couldn't act like that naturally."
"Turn the light into the room," begged Griswell. "See if John--if John is--"
He could not put the ghastly thought into words, but Buckner understood.
He swung the beam around, and Griswell had never dreamed that the sight of the gory body of a murdered man could bring such relief.
"He's still there," grunted Buckner. "If he walked after he was killed, he hasn't walked since. But that thing--"
Again he turned the light up the stair, and stood chewing his lip and scowling. Three times he half lifted his gun. Griswell read his mind. The sheriff was tempted to plunge back up that stair, take his chance with the unknown. But common sense held him back.
"I wouldn't have a chance in the dark," he muttered. "And I've got a hunch the light would go out again."
He turned and faced Griswell squarely.
"There's no use dodgin' the question. There's somethin' hellish in this house, and I believe I have an inklin' of what it is. I don't believe you killed Branner. Whatever killed him is up there--now. There's a lot about your yarn that don't sound sane; but there's nothin' sane about a flashlight goin' out like this one did. I don't believe that thing upstairs is human. I never met anything I was afraid to tackle in the dark before, but I'm not goin' up there until daylight. It's not long until dawn. We'll wait for it out there on that gallery."
The stars were already paling when they came out on the broad porch. Buckner seated himself on the balustrade, facing the door, his pistol dangling in his fingers. Griswell sat down near him and leaned back against a crumbling pillar. He shut his eyes, grateful for the faint breeze that seemed to cool his throbbing brain. He experienced a dull sense of unreality. He was a stranger in a strange land, a land that had become suddenly imbued with black horror. The shadow of the noose hovered above him, and in that dark house lay John Branner, with his butchered head--like the figments of a dream these facts spun and eddied in his brain until all merged in a gray twilight as sleep came uninvited to his weary soul.
He awoke to a cold white dawn and full memory of the horrors of the night. Mists curled about the stems of the pines, crawled in smoky wisps up the broken walk. Buckner was shaking him.
"Wake up! It's daylight."
Griswell rose, wincing at the stiffness of his limbs. His face was gray and old.
"I'm ready. Let's go upstairs."
"I've already been!" Buckner's eyes burned in the early dawn. "I didn't wake you up. I went as soon as it was light. I found nothin'."
"The tracks of the bare feet--"
"Gone!"
"Gone?"
"Yes, gone! The dust had been disturbed all over the hall, from the point where Branner's tracks ended; swept into corners. No chance of trackin' anything there now. Something obliterated those tracks while we sat here, and I didn't hear a sound. I've gone through the whole house. Not a sign of anything."
Griswell shuddered at the thought of himself sleeping alone on the porch while Buckner conducted his exploration.
"What shall we do?" he asked listlessly. "With those tracks gone, there goes my only chance of proving my story."
"We'll take Branner's body into the county seat," answered Buckner. "Let me do the talkin'. If the authorities knew the facts as they appear, they'd insist on you being confined and indicted. I don't believe you killed Branner--but neither a district attorney, judge nor jury would believe what you told me, or what happened to us last night. I'm handlin' this thing my own way. I'm not goin' to arrest you until I've exhausted every other possibility.
"Say nothin' about what's happened here, when we get to town. I'll simply tell the district attorney that John Branner was killed by a party or parties unknown, and that I'm workin' on the case.
"Are you game to come back with me to this house and spend the night here, sleepin' in that room as you and Branner slept last night?"
Griswell went white, but answered as stoutly as his ancestors might have expressed their determination to hold their cabins in the teeth of the Pequots: "I'll do it."
"Let's go then; help me pack the body out to your auto."
Griswell's soul revolted at the sight of John Branner's bloodless face in the chill white dawn, and the feel of his clammy flesh. The gray fog wrapped wispy tentacles about their feet as they carried their grisly burden across the lawn.
