sort. The boys feel it is a message from some person you met on your Egyptian travels and are much excited by it. I should reassure you that they have not been in the least alarmed by these occurrences and are indeed very reluctant to return to their grandmother’s care next week …’ Louisa passed the letter to Sarah. ‘I have to go home. Today. He’s back. He’s left me a message.’ Sarah went with her. On Louisa’s urgent instructions George had removed the boys at once back to their grandmother’s house so it was to a depleted household that they made their way from the station in a hansom cab. Louisa’s cook housekeeper, Mrs Laidlaw, and one maid, Sally Anne, were there to greet them. Louisa went straight to her studio. There on the table as George Browning had said sat the gold serpent. She had last seen it in the museum at Carstairs Castle. ‘Am I never to be rid of him?’ Louisa turned to Sarah in anguish. They had taken off their hats and coats and settled into chairs in the pretty drawing room overlooking the small garden of Louisa’s terraced London house. ‘Has he taken anything?’ ‘I don’t know.’ Louisa was staring round the room. ‘I haven’t noticed anything. There is only one thing he wants.’ ‘And is it there?’ Louisa shrugged. Standing up she led the way back into her studio and stood in front of the davenport where she did her correspondence. The studio was very cold; there was a strange smell in there she couldn’t immediately identify – not paint. Not linseed oil, or charcoal. Something sweet and slightly exotic. She shivered. ‘I put it in there. In the secret drawer.’ ‘See if it’s there.’ Louisa put her hand out to the polished wood of the desk lid. Then she shook her head. ‘Supposing he’s watching me.’ ‘Watching?’ Sarah glanced over her shoulder uneasily. ‘How could he be watching?’ ‘How could he do any of the things he does?’ Louisa replied crossly. She moved away from the desk. ‘He has been in this room. How else could the snake have got here? It is a message. A warning. Oh, Sarah what am I to do? Can’t you feel it? There is something here. Someone.’ She picked up the piece of paper with its strange illegible message and stared at it, then with it still in her hand she turned on her heels and swept out of the room with Sarah behind her. In the drawing room where Mrs Laidlaw had brought them a tray of tea Louisa threw the piece of paper with its scrawled hieroglyphics down onto the table. ‘What does it say? Can you read it?’ Louisa shook her head. Bending over it she ran her finger lightly over the symbols which had been inscribed there, then drew her hand away sharply. ‘What is it? What’s wrong?’ Sarah’s blue eyes were fixed on the paper. ‘Nothing. It felt hot. My imagination.’ Sarah glanced up sharply. ‘Are you sure?’ Louisa shrugged. ‘I’m sure of nothing. I don’t know why he’s left this. He must realise I can’t read it.’ ‘He’s just trying to frighten you. Tear it up.’ Louisa shook her head. ‘Supposing it’s important. These symbols. They have power.’ ‘Exactly.’ Sarah stood up. She reached for the paper. ‘If you won’t destroy it, I will.’ About to throw it into the fireplace she stopped with a gasp. The figure in front of them was no more substantial than a wisp of mist but both women saw it. Both shrank back. The paper dropped from Sarah’s hand and she fell back into her chair, white-faced. ‘Dear God!’ Louisa’s whisper was barely audible. ‘The djinn. The evil djinn!’ Already the figure had gone. It had been no more than a shadow. ‘What was that?’ Sarah’s voice shook. ‘Hatsek. The priest of Sekhmet. Two priests follow my ampulla and fight over it.’ Louisa’s voice was dreamlike. ‘Hassan called them djinn. The paper that came with the bottle was inscribed with their names. I don’t read hieroglyphs but I suppose this is what is
