One day, however, as he was going over the house in Curzon Street, in company with Lady Clementina’s solicitor and Sybil herself, burning packages of faded letters, and turning out drawers of odd rubbish, the young girl suddenly gave a little cry of delight.

‘What have you found, Sybil?’ said Lord Arthur, looking up from his work, and smiling.

‘This lovely little silver bonbonnière, Arthur. Isn’t it quaint and Dutch? Do give it to me! I know amethysts won’t become me till I am over eighty.’

It was the box that had held the aconitine.

Lord Arthur started, and a faint blush came into his cheek. He had almost entirely forgotten what he had done, and it seemed to him a curious coincidence that Sybil, for whose sake he had gone through all that terrible anxiety, should have been the first to remind him of it.

‘Of course you can have it, Sybil. I gave it to poor Lady Clem myself.’

‘Oh! thank you, Arthur; and may I have the bonbon too? I had no notion that Lady Clementina liked sweets. I thought she was far too intellectual.’

Lord Arthur grew deadly pale, and a horrible idea crossed his mind.

Bonbon, Sybil? What do you mean?’ he said in a slow, hoarse voice.

‘There is one in it, that is all. It looks quite old and dusty, and I have not the slightest intention of eating it. What is the matter, Arthur? How white you look!’
