The room into which they had been led was large and dark. Standing still they waited while their guide opened the shutters allowing the bright sunlight to flood the room. As they stared round there was a moment’s stunned silence, then at last it was Venetia who spoke first. ‘My goodness.’ She gasped with a nervous laugh. ‘How amazing!’

The items on display nearest to them, the bows and arrows, the huge beautiful feathered head-dress, the beaded jewellery, the bison skins, had been brought back so they were told by Lord Carstairs the previous year. ‘He went right across America,’ their informant told them, clearly awe-struck. ‘He lived with the various tribes he encountered. The Sioux; the Cheyenne. They made him welcome and he smoked the peace pipe with them.’ He indicated the large pipe decorated with coloured bands and feathers. ‘He has been studying their religion and their beliefs. He witnessed the Sun Dance.’ He paused, obviously expecting them to look impressed. ‘Beyond the American exhibits you will see those his lordship brought back from the Indian subcontinent in 1870. Beautiful silks and brocades as you will notice; items from Hindu temples and gifts he received from the maharajahs and British dignitaries with whom he stayed.’

Louisa was not listening. She had wandered past the American items and the Indian, past a huge glass-fronted bookcase and display cabinets of every shape and size, to the back of the room. In the corner, standing upright in the shadows, was the unmistakable painted face and body of an Egyptian mummy case. She closed her eyes, steadying her breathing with an effort.

‘Ah, Mistress Shelley. You have discovered Lord Carstairs’s Egyptian collection.’ The voice beside her was soft and ingratiating.

She gave a nervous smile. ‘He has a great many interesting items.’

‘Indeed.’ The factor glanced over his shoulder. The other three women were gathered around a glass case, staring down at a mass of beautiful shells. ‘Wampum,’ Venetia repeated, baffled, reading from a card inside the case.

Louisa stepped away from him. His presence beside her made her feel uncomfortable. She walked over to a table nearby and stared down at the items displayed on it. One stood out from them all. A small carved statue of a coiled snake. Without thinking she picked it up and examined it. ‘Solid gold, Mistress Shelley.’ The factor was still there at her elbow.

She stared down at the item in her hands, holding her breath. Almost she could hear Roger Carstairs’s voice in her head. ‘So, Mrs Shelley. You came to find me after all…’ The sound was so real she glanced up, shocked. But it was her imagination. Hastily she set the item back in its place and walked away. She glanced again with some distaste at the mummy, then moved on and stopped, staring at the wall. Framed in ebony with a deep terracotta mount she found herself looking at one of her own watercolours. A painting of the temple at Edfu.

She gasped.

The man beside her nodded. ‘You recognise it, of course.’

She spun to face him. ‘Where did he get that?’

‘He bought it, Mistress Shelley. In London.’ He bowed. A minimal movement betrayed a touch of mockery beneath the respect. ‘He has attended all your exhibitions, Mistress Shelley.’

Her stomach tightened with fear as she met his eyes. ‘Indeed, Mr Dunglass. I’m flattered at his interest.’ She managed to hold his gaze unwaveringly.

He looked away first. ‘So, madam, have you seen the next exhibit?’ He smiled again. ‘An example of one of the most poisonous of Egyptian snakes -’ He broke off as her hand flew to her mouth. In the case in front of her on a bed of pale dry sand lay a coiled snake, its head with spread hood rising out of the dry skin, its tiny button eyes fixed balefully on some imagined desert distances.

Louisa turned away with a cry of distress. It was so like the snake that had killed Hassan. The same shape, same length, same colour – its eyes were similar. Unblinking. Beady. Missing nothing.

‘It’s dead, Louisa.’ The hand on her arm was firm. Katherine was beside her. ‘Come away. Don’t look at it.’

‘Katherine – ’

‘I know, my dear. They told me all about it. And the way he conjured a snake onto our dahabeeyah. Magic snakes. Evil magic.’ She glanced round the room. Nearby was a wooden statue of a child holding a snake in its hand. The inscription underneath said, ‘Horus of the Snakes’. She shuddered. ‘Dirty magic. All his efforts to make himself a so-called master of the occult, and what for? A small room in the back of beyond and a few boxes of stolen mementoes.’

‘I beg your pardon?’ Mr Dunglass had overheard her. He was bristling with indignation. ‘Nothing here has been stolen. Everything was bought or given freely.’

‘Really?’ Louisa looked at him bitterly.

‘Really!’ The man glared at her.

Katherine shuddered. ‘Well, I don’t envy him this. I really don’t.’ She reached over and thumped the glass case with her folded parasol. The snake moved infinitesimally.

Louisa swallowed. Clutching her shawl around her shoulders she moved away from the Egyptian corner of the room to stand in front of the American head-dress with its regal glossy feathers, concentrating on the exquisite workmanship, the detail, the tiny beads.

Katherine moved on too, standing beside Sarah and Venetia, staring at some clay pots, laughing softly as Venetia, oblivious to the earlier exchange, pointed out some detail in the swirling decorations.

The hiss was so quiet Louisa barely heard it. For a moment she didn’t react, then she spun round staring back at the case. From where she was standing she could see an almost invisible film of dust on the glass. Nothing moved. She clenched her fists. Stupid. It was her imagination. Her idiotic, feverish, over-active imagination.

Behind her she heard Venetia’s voice. ‘And Lord Carstairs’s darling boys? Are they at home at the moment?’ and Dunglass’s grunt. ‘Aye. They are.’ He did not sound impressed.

‘We would so like to meet them, wouldn’t we, Sarah?’ Venetia clung to her hostess’s arm for a moment.

Louisa saw the factor’s eyebrow rise almost to his hairline. ‘I have no idea where the boys are, Mistress. You’d have to be speaking to Mr Gordon, their tutor, about them.’ His tone implied that their whereabouts was something he for one would rather not look into too closely.

‘We’ll do that.’ Venetia simpered at him. ‘We know dear Lord Carstairs so well, I’m sure he would wish us to enquire after his sons. Are they not at Eton with your elder boy, Louisa?’ She turned and raised an eyebrow.

‘I don’t think so,’ Louisa returned sharply.

Dunglass shook his head. ‘They’ve been expelled from every school in the country! I doubt his lordship could find one to hold them. That’s why they have a tutor.’ His lips tightened. ‘Believe me, ladies, I doubt you’d want to meet them.’ He folded his arms firmly.

Sarah and Venetia looked shocked. It was Venetia who voiced what was going through both ladies’ minds. ‘I don’t think you should speak like that about Lord Carstairs’s sons, Mr Dunglass.’

‘No?’ The man snorted. ‘I’m thinking their father would agree with me!’

‘Really?’ Venetia simpered at him. ‘Oh my goodness! In which case -’ She fluttered her eyelashes at the man in apology and Louisa turned away sharply. Was it possible that Venetia still had hopes of the odious Carstairs? Surely not? But here she was, still unmarried, still travelling with her brother and his long-suffering wife. Still hankering after a rich titled husband. She gave an involuntary shudder. No doubt the handsome Lord Carstairs would fit her imaginary ideal in every particular. She did not, after all, know what the real man was like!

‘Louisa dear? It’s time we made a move for home.’ Sarah’s gentle hand on her arm made her jump. ‘Have you seen enough?’

‘Quite enough.’ Louisa glanced towards the back of the room where the case containing the stuffed cobra was standing in a patch of sunlight from the high window. There was no movement; nothing at all in that corner of the room. So why did the very stillness make her feel uneasy?

In her dream she was standing at the mouth of the cave, staring into the darkness, anxious to escape the glare of the sun. Hassan was beside her, his handsome face eager, gentle, so very loving. He turned with that serious smile she loved so much and held out his hand. ‘Come, my Louisa; we will go in out of the heat.’

She reached towards him. She only had to speak to save his life. All she had to say was, No, come back. Don’t go in. But the words would not come. Her throat was constricted, her mouth full of sand. There was a roaring in her ears like the waters of the cataract in flood and then it happened. In slow motion she saw the sinuous movement of the snake; saw it head towards Hassan, saw it rise up, its hood spread, its mouth open -. Her scream this time, as always, came too late; her waking, alone, in her bed, desolate.

She sat up, sobbing, aware of the moonlight flooding through a crack in the curtains. The room was very quiet. Not a breath of air stirred the wisteria on the wall outside. The night was very hot. Her face still wet with tears, she climbed out of bed and went to push back the curtains. The tall windows opened out onto the balcony which ran the entire length of the first floor of the house overlooking the gardens. Pushing them open she stepped outside and leant on the stone balustrade. The countryside was as bright as day. She could see every detail of the garden with its formal hedges and beds and its vistas across the parkland and the loch to the mountains beyond.

‘So, Louisa. You came to visit my house. You couldn’t resist seeing where I lived. I saw you pick up my golden snake. I felt you call me.’
