It was the darkest hour of the night, nearly three o'clock in the morning, and the chilling fog clung to the city like a ghost. Prudence Merryweather reluctantly concluded that it was an uncomfortably suitable time and setting in which to pay a call on the man known as the Fallen Angel.

She shivered in spite of her bold resolve as the hackney drew to a halt in front of the mist-shrouded door of the town house. The new gas lamps that had been installed in this part of town were useless against the thick mist. An eerie silence gripped the cold, dark street. The only sounds were the rattle of the carriage and the thud of the horses' hooves on the pavement.

Prudence briefly considered ordering the coachman to turn the hackney around and drive her straight home. But she banished the thought as quickly as it had come. She knew she must not falter now. Her brother's life was at stake.

She summoned up her courage, adjusted her spectacles more firmly in place, and stepped down from the cab. She tugged the hood of her aging gray wool cloak down to shield her face as she started determinedly up the steps of the town house. Behind her the hackney began to roll forward down the street.

Prudence stopped and whirled around in alarm. "Where do you think you're going, my good man? I said I would give you an extra few coins to wait for me. I'll only be a few minutes."

"Don't fret yerself none, miss. I was just adjustin‘ the reins, is all." The coachman was a featureless dark blob in his heavily caped great­coat and a hat that was pulled down low over his ears. His voice was slurred from the gin he had been drinking all evening to ward off the bitter chill. "I told ye, I'd wait for ye."

Prudence relaxed slightly. "See that you're still here when I return. Otherwise I shall be quite stranded when I finish my business."

"Business, huh? Is that what ye call it?" The coachman sniggered as he tipped his gin bottle and poured the contents down his throat. "Pretty fancy piece o‘ business, if you ask me. Mayhap yer gentleman friend will want ye to warm his bed for the rest o' the night. Bloody damn cold this evenin‘."

Prudence scowled at him but decided there was nothing to be gained from engaging in an argument with a drunken coachman at this late hour. She did not have the time for such nonsense.

She gathered the enveloping cloak more tightly about her and hurried on up the steps to the front door of the town house. The upstairs windows were unlit. Perhaps the notorious owner of the house was already abed.

From all accounts that would be an unusual state of affairs. It was said that the legendary Earl of Angelstone seldom went to bed before dawn. The Fallen Angel had not earned his formidable reputation by keeping reasonable hours. Everyone knew the devil preferred the cover of night.

Prudence hesitated before raising her gloved hand to knock on the door. She was well aware that what she was about to do carried a certain risk. She was country bred and new to London, but she was not so naive as to think it was normal for ladies to pay calls on gentlemen at any hour, let alone at three in the morning.

Prudence rapped sharply on the door.

It seemed to take forever until a disgruntled-looking, half-dressed butler opened the door. He was a balding, heavy jawed man who put Prudence in mind of a large, ferocious hound. The candle he held in one hand revealed first annoyance and then growing disgust on his bleak features. He took in the sight of Prudence's cloaked and hooded figure with severely disapproving eyes.

"Yes, miss?"

Prudence took a deep breath. "I have come to call upon his lord­ship."

"Have you, indeed?" The butler's lip curled into a sneer that would have suited Cerberus, the three-headed dog that was said to guard the entrance to Hades. "I regret to inform you that his lordship is not at home."

"He most certainly is." Prudence knew she must be firm if she was to get past the Fallen Angel's hellhound. "I checked with my sources before making my decision to call upon him. Please inform him imme­diately that he has a visitor."

"And who should I say is calling?" the butler asked in sepulchral tones.

"A lady."

"Not bloody likely. No lady would be here at this hour. Take your­self off, you obnoxious little baggage. His lordship doesn't consort with your sort. If he's in the mood for a bit o‘ muslin he can look a good deal higher than a strumpet fresh off the streets."

Prudence went hot beneath the insults. This was clearly going to be even more awkward than she had anticipated. She set her teeth. "Be so good as to inform his lordship that a party who has an interest in his forthcoming duel wishes to see him."

The butler stared at her in astonishment. "And what, pray tell, would a woman of your sort know about his lordship's personal af­fairs?"

"A great deal more than you do, apparently. If you don't tell Angelstone that he has a caller, I vow you will live to regret it. I assure you that your position in this household depends upon your informing him I am here."

The butler did not appear to be entirely convinced by the threat, but he was starting to waver. "Wait here."

He slammed the door, leaving Prudence standing on the step. The icy fingers of the fog crept close and wrapped themselves around her. She huddled deeper into her cloak. This was turning out to be one of the most miserable evenings she had spent in her entire life. Things had been so much simpler in the country.

The door opened again a moment later. The butler looked down his nose at Prudence and grudgingly indicated she should enter.

"His lordship will see you in the library."

"I should think so." Prudence stepped quickly over the threshold, grateful to escape the clutches of the fog, even if it meant walking into the very jaws of hell.

The butler opened the library door and held it for her. Prudence swept past him into a dark, shadowed room that was lit only by a small blaze on the hearth. The door closed behind her just as she realized there was no sign of Angelstone.

"My lord?" Prudence came to an abrupt halt and peered intently into the gloom. "Sir? Are you here?"

"Good evening, Miss Merryweather. I trust you will forgive my butler's rudeness." Sebastian, Earl of Angelstone, rose slowly from the depths of a huge wing chair that faced the hearth. He had a large black cat tucked under one arm. "You must understand your visit is somewhat unexpected. Especially considering the circumstances and the hour."

"Yes, my lord. I am aware of that." Prudence caught her breath at the sight of him. She had danced with Sebastian earlier that evening, but that was only the first time she had met the Fallen Angel. She realized now it would take more than one or two encounters before she adjusted to the impact he made on her senses.

Angelstone was anything but angelic in either appearance or tem­perament. It was said in the drawing rooms of the ton that he bore a strong resemblance to the Lord of the Underworld. It was true that it would take a formidable imagination to envision him with a pair of wings and a halo.

The firelight flickering behind Sebastian seemed a little too atmo­spheric tonight. The glow of the flames threw his fierce, saturnine features into harsh relief. His black hair was cut short. His curious, amber eyes blazed with a cold, penetrating intelligence. His body was hard and lean. Prudence knew from her experience with him on the dance floor that Sebastian moved with a lazy, dangerous masculine grace.

He was clearly dressed for the privacy of his own home, not for receiving visitors. His white cravat hung loose around his neck and his ruffled shirt was unfastened far enough to reveal the crisp black hair on his chest. His buff-colored breeches hugged the sinewy lines of his thighs. He had not yet removed his black, mirror-polished Hessians.
