Mark Chadbourn - The silver skull

Far beneath the slow-moving Thames, a procession of flickering lights drew inexorably towards London from the east. The pace was funereal, the trajectory steady, purposeful. In that hour after midnight, the spectral glow under the black waters passed unseen by all but two observers.

"There! What are they, sir?" In the lantern light, the guard's fear was apparent as he peered over the battlements of the White Tower, ninety feet above the river.

Matthew Mayhew, who had seen worse things in his thirty years than the guard could ever dream in his worst fever-sleep, replied with boredom, "I see the proud heart of the greatest nation on Earth. I see a city safe and secure within its walls, where the queen may sleep peacefully."

"There!" The guard pointed urgently.

"A waterman has met with disaster." Mayhew sighed. With a temper as short as his stature, the Tower guards had learned to handle him with care and always praised the fine court fashions he took delight in parading.

The guard gulped the cold air of the March night. "And his lantern still burns on the bottom? What of the other lights? And they move-"

"The current."

The guard shook his head. "They are ghosts!"

Mayhew gave a dismissive snort.

"There are such things! Samuel Hale saw the queen's mother walking with her head beneath her arm in the Chapel of Saint Peter ad Vincula. Why, the Tower is the most haunted place in England! The Two Princes, Margaret Pole, Lady Jane Grey all seen here, Master Mayhew. Damned by God to walk this world after their deaths."

Mayhew studied the slow-moving lights, imagining fish in the deep with their own candles to guide their way through the inky dark.

The guard's fear made his lantern swing so wildly the shadows flew across the Tower.

Steadying the lantern, Mayhew said, "When this great fortress was built five hundred years gone, King William had the mortar tempered with the blood of beasts. Do you know why that was?"

"No, no. I-"

"Suffice it to say," Mayhew interrupted wearily, "that you are safe here from all supernatural threat."

The guard calmed a little. "Safe, you say?"

"England's defences are built on more than the rock of its people."

The lights veered away from the centre of the river towards the Tower of London where it nestled inside the old Roman walls, guarding the eastern approach to the capital. Mayhew couldn't prevent a shiver running up his spine.

"Complete your rounds," he said sharply, overcompensating in case the guard had seen his weakness. "We must ensure that the White Tower remains secure against England's enemies."

"And the prisoner you are charged to guard?"

"I will attend to him." Mayhew pressed a scented handkerchief against his nose to block out the stink of the city's filth caught on the wind. Sometimes it was unbearable. He hated being away from the court where the virtues of life were more apparent, hated the boredom of his task, and at that moment hated that he was caught on the cold summit of the White Tower when he should have been inside by the fire.

He cast his eye around the fortress where pools of darkness were held back by the lanterns strung along the walkways among the wards. The only movement came from the slow circuit of the night watch.

The Tower of London was an unassailable symbol of England. Solid Kentish ragstone formed the bulk of the impregnable White Tower, protected by its own curtain wall and moat, with a further curtain wall and thirteen towers guarding the Inner Ward beyond. Finally, there was the Outer Ward, with another solid wall, five towers, and three bastions. Everything valuable to the nation lay within the walls-the Crown jewels, the treasury, the Royal Mint, the armoury, and England's most dangerous prisoners, including Mayhew's personal charge.

As he made his way down the stone steps, he was greeted by the clatter of boots ascending and the light of another lantern. William Osborne appeared, his youthful face and intelligent grey eyes unsettled. Mayhew contemptuously wondered if he now regretted giving up his promising career in the law to join the Queen's Service out of love for his country, not realising what would be asked of him.

"What is it?" Mayhew demanded.

"A disturbance. At the Traitors' Gate."

Where the river lights were heading, Mayhew thought. "The gate remains secure, and well guarded?" he asked.

Osborne's face loomed white in the lamplight. "There are six men upon it, as our Lord Walsingham demanded."

"And yet?"

Osborne's voice quavered with uncertainty. "The guards say the restraining beam moves of its own accord. Bolts draw without the help of human hand. Is this what we always feared?"

Pushing past him with irritation, Mayhew snapped, "You know as well as I that the Tower is protected. These guards are frighted like maidens." For all his contempt at his colleague's words, Mayhew's chest tightened in apprehension.

Walsingham said it could never happen, he reminded himself. He told the queen Burghley

Trying to maintain his decorum, he descended to the ground floor with studied nonchalance and stepped out into the Inmost Ward. The whitewashed walls of the Tower glowed in the lantern light.

"Listen!" Osborne's features flared in the gloom as he raised his lantern to illuminate the way ahead.

The steady silence of the Tower was shattered by a cacophony of roars and howls, barks, shrieks, and high-pitched chattering. In the Royal Menagerie, the lions, leopards, and lynxes threw themselves around their pens, while the other exotic beasts tore at the mud of their enclosures in a frenzy.

"What do they sense?" There was a querulous tremble in Osborne's voice.

Scanning the Inmost Ward for any sign of movement, Mayhew relented. "You know."

Osborne winced at his words. "Are you not afraid?"

"This is the work we were charged to do, for queen and country. Raise the alarm. Then we must take ourselves to the prisoner."

Within moments, guards raced to their positions under Osborne's direc tion. Venturing to the gate, they peered beyond the curtain wall to where the string of lanterns kept the dark at bay.

"Nothing," Osborne said with relief, his voice almost lost beneath the screams of the animals.

Mayhew kept his attention on Saint Thomas's Tower in the outer curtain wall. Beyond it was the river, and beneath it lay the water entrance that had become known as Traitors' Gate, after the enemies of the Crown who had been transported through it to imprisonment or death. The guards had disappeared inside, but there was no clamour.

After five minutes, Osborne's relief was palpable. "A false alarm, then. Perhaps it was only Spanish spies. With the country on the brink of war, they must be operating everywhere. Yes?"

A guard emerged from Saint Thomas's Tower, pausing for a moment on the threshold. Mayhew and Osborne watched him curiously. With an odd, lurching gait, he picked a winding path towards them.

"Is he drunk?" Mayhew growled. "His head will be on the block by noon if he has deserted his post."

"I I do not" The words died in Osborne's throat as the guard's path became more erratic. His jerky movements were deeply upsetting, as if he had been afflicted by a palsy.

Mayhew cursed under his breath. "I gave up a life at court for this."

As the guard neared, they saw his hands continually went to his head as if searching for a missing hat. Despite himself, Mayhew reached for the knife hidden in the folds of his cloak.

"I am afraid," Osborne whispered.

"Do you hear music?" Mayhew cocked his head. "Like pipes playing, caught on the breeze?" As he breathed deeply of the night air, he realised the foul odour of the city had been replaced by sweet, seductive scents that took him back to his childhood. A tear stung his eye. "That aroma," he noted, "like cornfields beneath the summer moon." He inhaled. "Honey, from the hive my grandfather kept."
