“Demon?” said Tom Byrd, and gave Grey a look of profound betrayal.

“Something of the kind, I believe,” Grey said, and coughed. “If such a thing should exist, which I doubt it does.”

A chill of uncertainty seemed to have overtaken the party with this demonstration of the horse’s reluctance. There was shuffling and murmuring, and heads turned to glance back in the direction of the tavern.

Stephan, magnificently disregarding this tendency to pusillanimity in his troops, clapped Karolus on the neck and spoke to him encouragingly in German. The horse snorted and arched his neck, but still resisted Tom Byrd’s tentative yanks on his halter. Instead, he swiveled his enormous head toward Grey, jerking Byrd off his feet. The boy lost his grip on the rope, staggered off balance, trying vainly to keep hold of the lantern, and finally slipped on a stone submerged in the mud, landing on his buttocks with a rude splat.

This mishap had the salutary effect of causing the diggers to roar with laughter, restoring their spirits. Several of the torches had by now been extinguished by the rain, and everyone was thoroughly wet, but goatskin flasks and pottery jugs were produced from a number of pockets and offered to Tom Byrd by way of restorative, being then passed round the company in sociable fashion.

Grey took a deep swig of the fiery plum liquor himself, handed back the jug, and came to a decision.

“I’ll ride him.”

Before Stephan could protest, Grey had taken a firm grip on Karolus’s mane and swung himself up on the stallion’s broad back. Karolus appeared to find Grey’s familiar weight soothing; the broad white ears, which had been pointing to either side in suspicion, rose upright again, and the horse started forward willingly enough at Grey’s nudge against his sides.

Tom, too, seemed heartened, and ran to pick up the trailing halter rope. There was a ragged cheer from the diggers, and the party moved awkwardly after them, through the yawning gates.

It seemed much darker in the churchyard than it had looked from outside. Much quieter, too; the jokes and chatter of the men died away into an uneasy silence, broken only by an occasional curse as someone knocked against a tombstone in the dark. Grey could hear the patter of rain on the brim of his hat, and the suck and thump of Karolus’s hooves as he plodded obediently through the mud.

He strained his eyes to see what lay ahead, beyond the feeble circle of light cast by Tom’s lantern. It was black-dark, and he felt cold, despite the shelter of his greatcoat. The damp was rising, mist coming up out of the ground; he could see wisps of it purling away from Tom’s boots, disappearing in the lantern light. More of it drifted in an eerie fog round the mossy tombstones of neglected graves, leaning like rotted teeth in their sockets.

The notion, as it had been explained to him, was that a white stallion had the power to detect the presence of the supernatural. The horse would stop at the grave of the succubus, which could then be opened and steps taken to destroy the creature.

Grey found a number of logical assumptions wanting in this proposal; chief among which—putting aside the question of the existence of succubi, and why a sensible horse should choose to have anything to do with one—was that Karolus was not choosing his own path. Tom was doing his best to keep slack in the rope, but as long as he held it, the horse was plainly going to follow him.

On the other hand, he reflected, Karolus was unlikely to stop anywhere, so long as Tom kept walking. That being true, the end result of this exercise would be merely to cause them all to miss their suppers and to render them thoroughly wet and chilled. Still, he supposed they would be still more wet and chilled if obliged actually to open graves and perform whatever ritual might follow—

A hand clamped itself on his calf, and he bit his tongue—luckily, as it kept him from crying out.

“You are all right, Major?” It was Stephan, looming up beside him, tall and dark in a woolen cloak. He had left aside his plumed helmet, and wore a soft-brimmed wide hat against the rain, which made him look both less impressive and more approachable.

“Certainly,” Grey said, mastering his temper. “How long must we do this?”

Von Namtzen lifted one shoulder in a shrug.

“Until the horse stops, or until Herr Blomberg is satisfied.”

“Until Herr Blomberg begins wanting his supper, you mean.” He could hear the bürgermeister’s voice at a distance behind them, lifted in exhortation and reassurance.

A white plume of breath floated out from under the brim of von Namtzen’s hat, the laugh behind it barely audible.

“He is more … resolute?… than you might suppose. It is his duty, the welfare of the village. He will endure as long as you will, I assure you.”

Grey pressed his bitten tongue against the roof of his mouth, to prevent any injudicious remarks.

Stephan’s hand was still curled about his leg, just above the edge of his boot. Cold as it was, he felt no warmth from the grasp, but the pressure of the big hand was both a comfort and something more.

“The horse—he goes well, nicht wahr?”

“He is wonderful,” Grey said, with complete sincerity. “I thank you again.”

Von Namtzen flicked his free hand in dismissal, but made a pleased sound, deep in his throat. He had—against Grey’s protests—insisted upon making the stallion a gift to Grey, “in token of our alliance and our friendship,” he had said firmly, clapping Grey upon both shoulders and then seizing him in fraternal embrace, kissing him formally upon both cheeks and mouth. At least, Grey was obliged to consider it a fraternal embrace, unless and until circumstance might prove it otherwise.

But Stephan’s hand still curled round his calf, hidden under the skirt of his greatcoat.

Grey glanced toward the squat bulk of the church, a black mass that loomed beyond the churchyard.

“I am surprised that the priest is not with us. Does he disapprove of this—excursion?”

“The priest is dead. A fever of some kind, die rote Ruhn, more than a month since. They will send another, from Strausberg, but he has not come yet.” Little wonder; a large number of French troops lay between Strausberg and the town; travel would be difficult, if not impossible.

“I see.” Grey glanced back over his shoulder. The diggers had paused to open a fresh jug, torches tilting in momentary distraction.

“Do you believe in this—this succubus?” he asked, careful to keep his voice low.

Rather to his surprise, von Namtzen didn’t reply at once. At last, the Hanoverian took a deep breath and hunched his broad shoulders in a gesture not quite a shrug.

“I have seen … strange things from time to time,” von Namtzen said at last, very quietly. “In this country, particularly. And a man is dead, after all.”

The hand on his leg squeezed briefly and dropped away, sending a small flutter of sensation up Grey’s back.

He took a deep breath of cold, heavy air, tinged with smoke, and coughed. It was like the smell of grave dirt, he thought, and then wished the thought had not occurred to him.

“One thing I confess I do not quite understand,” he said, straightening himself in the saddle. “A succubus is a demon, if I am not mistaken. How is it, then, that such a creature should take refuge in a churchyard, in consecrated ground?”

“Oh,” von Namtzen said, sounding surprised that this was not obvious. “The succubus takes possession of the body of a dead person, and rests within it by day. Such a person must of course be a corrupt and wicked sort, filled perhaps with depravity and perversion. So that even within the churchyard, the succubus will suitable refuge find.”

“How recently must the person have died?” Grey asked. Surely it would make their perambulations more efficient were they to go directly to the more recent graves. From the little he could see in the swaying light of Tom’s lantern, most of the stones nearby had stood where they were for decades, if not centuries.

“That I do not know,” von Namtzen admitted. “Some people say that the body itself rises with the succubus; others say that the body remains in the grave, and by night the demon rides the air as a dream, seeking men in their sleep.”

Tom Byrd’s figure was indistinct in the gathering fog, but Grey saw his shoulders rise, nearly touching the brim of his hat. Grey coughed again, and cleared his throat.

“I see. And … er … what, precisely, do you intend to do, should a suitable body be located?”

Here von Namtzen was on surer ground.

“Oh, that is simple,” he assured Grey. “We will open the coffin, and drive an iron rod through the corpse’s heart. Herr Blomberg has brought one.”

Tom Byrd made an inarticulate noise, which Grey thought it wiser to ignore.

“I see,” he said. His nose had begun to run with the cold, and he wiped it on his sleeve. At least he no longer felt hungry.

They paced for a little in silence. The bürgermeister had fallen silent, too, though the distant sounds of squelching and glugging behind them indicated that the digging party was loyally persevering, with the aid of more plum brandy.

“The dead man,” Grey said at last. “Private Koenig. Where was he found? And you mentioned marks upon the body—what sort of marks?”

Von Namtzen opened his mouth to answer, but was forestalled. Karolus glanced suddenly to the side, nostrils flaring. Then he flung up his head with a great harrumph! of startlement, nearly hitting Grey in the face. At the same moment, Tom Byrd uttered a high, thin scream, dropped the rope, and ran.

The big horse dropped his hindquarters, slewed round, and took off, leaping a small stone angel that stood in his path; Grey saw it as a looming pale blur, but had no time to worry about it before it passed beneath the stallion’s outstretched hooves, its stone mouth gaping as though in astonishment.

Lacking reins and unable to seize the halter rope, Grey had no recourse but to grip the stallion’s mane in both hands, clamp his knees, and stick like a burr. There were shouts and screams behind him, but he had no attention to spare for anything but the wind in his ears and the elemental force between his thighs.

They bounded like a skipping cannonball through the dark, striking the ground and rocketing upward, seeming to cover leagues at a stride. He leaned low and held on, the stallion’s mane whipping like stinging nettles across his face, the horse’s breath loud in his ears—or was it his own?

Through streaming eyes, he glimpsed light flickering in the distance, and realized they were heading now for the village. There was a six-foot stone wall in the way; he could only hope the horse noticed it in time.

He did; Karolus skidded to a stop, divots of mud and withered grass shooting up around him, sending Grey lurching up onto his neck. The horse reared, came down, then turned sharply, trotted several yards, and slowed to a walk, shaking his head as though to try to free himself of the flapping rope.

Legs quivering as with ague, Grey slid off, and with cold-stiff fingers, grasped the rope.

“You big white bastard!” he said, filled with the joy of survival, and laughed. “You’re bloody marvelous!”

Karolus took this compliment with tolerant grace, and shoved at him, whickering softly. The horse seemed largely over his fright, whatever had caused it; he could but hope Tom Byrd fared as well.

Grey leaned against the wall, panting until his breath came back and his heart slowed a bit. The exhilaration of the ride was still with him, but he had now a moment’s heed to spare for other things.

At the far side of the churchyard, the torches were clustered close together, lighting the fog with a reddish glow. He could see the digging party, standing in a knot shoulder-to-shoulder, all in attitudes of the most extreme interest. And toward him, a tall black figure came through the mist, silhouetted by the torch glow behind him. He had a moment’s turn, for the figure looked sinister, dark cloak swirling about him—but it was, of course, merely Captain von Namtzen.

“Major Grey!” von Namtzen called. “Major Grey!”

“Here!” Grey shouted, finding breath. The figure altered course slightly, hurrying toward him with long, stilted strides that zigged and zagged to avoid obstacles in the path. How in God’s name had Karolus managed on that ground, he wondered, without breaking a leg or both their necks?

“Major Grey,” Stephan said, grasping both his hands tightly. “John. You are all right?”

“Yes,” he said, gripping back. “Yes, of course. What has happened? My valet—Mr. Byrd—is he all right?”

“He has into a hole fallen, but he is not hurt. We have found a body. A dead man.”

Grey felt a sudden lurch of the heart.

“What—”

“Not in a grave,” the captain hastened to assure him. “Lying on the ground, leaning against one of the tombstones. Your valet saw the corpse’s face most suddenly in the light of his lantern, and was frightened.”

“I am not surprised. Is he one of yours?”

“No. One of yours.”

“What?” Grey stared up at the Hanoverian. Stephan’s face was no more than a pale oval in the dark. He squeezed Grey’s hands gently and let them go.

“An English soldier. You will come?”

He nodded, feeling the cold air heavy in his chest. It was not impossible; there were English regiments to north and to south of the town, no more than an hour’s ride away. Men off duty would often come into town in search of drink, dice, and women. It was, after all, the reason for his own presence here—to act as liaison between the English regiments and their German allies.

The body was less horrible in appearance than he might have supposed; while plainly dead, the man seemed quite peaceful, slumped half sitting against the knee of a stern stone matron holding a book. There was no blood nor wound apparent, and yet Grey felt his stomach clench with shock.
