made an uneasy bed for the night under a bush. Over the moors, a cromlech was dimly visible: best avoided, to Caulk’s mind, as the likely home of visps and leucomances.
The next day dawned with a pallid grey sky. Caulk looked out across a landscape of black moss, tarns like obsidian eyes, low hills. Against the grey morning, the vista was sombre. Caulk sighed and made a bleak meal of dried posset. Then he studied the strands of hair: they twitched in his hand, pointing north. He started walking, hopefully in the direction of Llantow tarn.
He had heard no owls overnight. He was not sure whether to be encouraged by this or not. If there were owl-witches, then perhaps they were keeping to their hunting grounds of Llantow. Or perhaps the owl-killer’s information was out of date and there
He kept walking, following the hair, which twitched and writhed like a worm. Towards late afternoon, a shimmering dark expanse that might, or might not, be Llantow tarn came into view, lying under a glowering range of hills. A rainbow glinted in its depths, swirls of rose and jade, and Caulk was immediately wary: he’d seen such things before, in Falling Water. Marsh-sprites and tarn-frits used them as a lure; Caulk looked pointedly away.
Around the tarn were clusters of small trees, with white bark and dark green foliage. A peppery scent filled the air — this must be what passed for spring in White Alster. Caulk’s nose began to itch, not good news, for someone needing to remain surreptitious. He took a determined breath and headed, via a circuitous route, toward the tarn.
If any owl-witches were in residence, it would be in the crags on the hillside, rather than around the tarn itself; apart from the trees, there was no adequate shelter. Caulk crouched low behind a thicket of juniper, dined off posset, waited for twilight.
Nothing. Still nothing — and then, just as the pitiful sprinkle of remaining stars pricked out, there was the rustle of wings overhead, and an owl soared out across the rippling face of the tarn. Caulk, stiff and cold in the juniper, saw through amplifying glasses the telltale extra limbs tucked underneath the wing span: little atrophied arms and legs that, when the shifting magic occurred, would flesh out into human shape.
Elation and relief were rapidly followed by adrenalin. The actual existence of an owl-witch now necessitated planning and capture, rather than a sorry return to Almery with a tale of failure. On the other hand, the attempted capture of a witch might result in no return to Almery at all. Caulk watched, wrestling with professional misgivings, as the owl-witch swooped down on something at the far end of the tarn. A thin shrieking filled the twilight, followed by sounds of bones being crunched. Caulk gave careful attention to the skies, and, seeing nothing, backed up the hillside. The best time to catch a witch would be during daylight, but, at the moment, he was too close to the hunting ground. He crawled up towards a pile of boulders, then hid. More witches flew out from the crags. Caulk counted five, including the initial sighting. He was so intent on the witches that he failed to smell the leucomance until it was almost upon him. Caulk turned at the last instant, to glimpse a narrow head, glowing eyes, bared teeth. The leucomance crouched and twittered at a pitch that made Caulk’s ears bleed. He threw a dagger, but the leucomance bounded up onto one of the boulders, where it sat grinning at him. Caulk cursed and the leucomance put a hand behind one pointed ear, grinning harder. Its genitals twitched, repulsing Caulk, who threw another dagger out of sheer irritation. The leucomance leaped high, there was the beat of wings in the darkness and the leucomance was gone with a sudden cry. All well and good, except that the commotion had attracted the attention of the remaining witches, who now came to perch on the boulder and watch Caulk with shining, intrigued eyes.
“Hold!” Caulk shouted, as the last witch came in to land and dropped the dead leucomance with a heavy thud. “I am Caulk the Witch-chaser!” He brandished two of the daggers, letting his coat fall open so that the others were clearly visible. “I have slain a nest of sea-hags on the coast of White Alster! I have hunted tarn-wights in the Tsombol Marsh, and weasel-witches in the polders of Taum!” He twitched the coat open further, displaying the scalps. “See these?”
“All too clearly,” an owl-witch said. She quivered, the little limbs extending and fleshing out, her round head elongating, until a woman wearing nothing but a feather cloak stood in front of Caulk. Vestigial breasts and a hooked nose did little for him, and the witch’s skin was a faint grey, reflecting the light from a patch of luminous moss. She smiled, displaying teeth as sharp as the leucomance’s. She preened before Caulk, who forced a look of reluctant admiration to cross his features.
“All those dead sisters,” the owl-witch said. Beside her, the others also metamorphosed. Two were clearly older than the others, but, like the sea-hags, they had a similar range of appearance. Another damned nest, Caulk thought, but kept the admiring expression in place.
“Do not try to make me feel guilt, madam,” Caulk said. “No witch loves another.”
“But we love witch-chasers
He could not take all of them down, and he knew it. “How do you feel about owl-killers?” Caulk asked.
A hissing, spitting moment of frenzy, during which Caulk stepped rapidly back and reached for longer knives. The first witch made a rattling noise in her throat and brought up a bony, bristling pellet, which she spat out at Caulk’s feet.
“What talk is this?”
“I was hired — no,
More hissing. Caulk again moved back.
“We know of Mott,” one of the older witches said. Her small mouth curled in disdain. “A wicked man.”
“No argument from me,” Caulk said quickly.
“Mott cannot come to White Alster,” the old witch said. She shrugged her shoulders and the cloak ruffled up. “He would die. He stole my hair.”
“Aha!” said Caulk. He held out the strand and snatched it back as she clawed towards it. “Would this be it, by any chance?”
“My hair!” The witch’s face was avid.
“You spoke of a compulsion,” another witch murmured.
Caulk laughed. “What benefit is there for me, in killing owl-witches?” He hefted the strand of hair higher, keeping it out of reach. “Your pelts bring nothing on the market. Your beauty—” and here Caulk gave a small bow, “is not prized in the flesh-pots of the south. Why would I bother, unless a pervulsion had been placed upon me?”
“I would kill you,” the eldest witch said, considering. “But I have a score to settle with Mott.”
Caulk looked towards the moss, conjured a small bolt of heat. The moss sizzled and fried.
“No more sting than a nettle,” a witch said, with scorn.
“Maybe not. But enough to fry a strand of hair,” replied Caulk. There was a moment of silence.
“A witch-chaser is not the best person to enlist,” the younger witch said.
The older one put her head on one side, regarded Caulk. “Not even for a price?”
“What kind of price?” Caulk said, very wary.
“Tell me,” the old witch said, “how happy are you, with your life?”
Caulk thought.
The young witch rustled her cloak, revealing hints of skin that were starting to become more appealing.
“Then I have an idea…” the old witch began.
Caulk’s boat put back into Almenomei harbour on a rising tide. He stepped out onto the dock, seeing the ancient town with different eyes, evaluating turrets and gables and eaves. Absently, he rubbed the sore place on his wrist: the old witch had not been gentle, but then, that wasn’t the way of owls, as Caulk now more fully appreciated. Yet, it was a small enough price to pay for the quietening of the pervulsion, which now lay still within his head.
He had been told to send word by courier to Mott, using a certain combination of digits and letters which, the
