She flung her hands out.

‘Fear! You remember, it was a long time before I would consent to sit for her? I felt sure in some way she would bring me misfortune.’

Raoul shrugged his shoulders.

‘Whereas, in actual fact, she brought you the exact opposite,’ he said drily. ‘All the sittings have been attended with marked success. The spirit of the little Amelie was able to control you at once, and the materializations have really been striking. Professor Roche ought really to have been present at the last one.’

‘Materializations,’ said Simone in a low voice. ‘Tell me, Raoul (you know that I know nothing of what takes place while I am in the trance), are the materializations really so wonderful?’

He nodded enthusiastically.

‘At the first few sittings the figure of the child was visible in a kind of nebulous haze,’ he explained, ‘but at the last séance—’

‘Yes?’

He spoke very softly.

‘Simone, the child that stood there was an actual living child of flesh and blood. I even touched her—but seeing that the touch was acutely painful to you, I would not permit Madame Exe to do the same. I was afraid that her self-control might break down, and that some harm to you might result.’

Simone turned away again towards the window.

‘I was terribly exhausted when I woke,’ she murmured. ‘Raoul, are you sure—are you really sure that all this is right? You know what dear old Elise thinks, that I am trafficking with the devil?’

She laughed rather uncertainly.

‘You know what I believe,’ said Raoul gravely. ‘In the handling of the unknown there must always be danger, but the cause is a noble one, for it is the cause of Science. All over the world there have been martyrs to Science, pioneers who have paid the price so that others may follow safely in their footsteps. For ten years now you have worked for Science at the cost of a terrific nervous strain. Now your part is done, from today onward you are free to be happy.’

She smiled at him affectionately, her calm restored. Then she glanced quickly up at the clock.

‘Madame Exe is late,’ she murmured. ‘She may not come.’

‘I think she will,’ said Raoul. ‘Your clock is a little fast, Simone.’

Simone moved about the room, rearranging an ornament here and there.

‘I wonder who she is, this Madame Exe?’ she observed. ‘Where she comes from, who her people are? It is strange that we know nothing about her.’

Raoul shrugged his shoulders.

‘Most people remain incognito if possible when they come to a medium,’ he observed. ‘It is an elementary precaution.’

‘I suppose so,’ agreed Simone listlessly.

A little china vase she was holding slipped from her fingers and broke to pieces on the tiles of the fireplace. She turned sharply on Raoul.

‘You see,’ she murmured, ‘I am not myself. Raoul, would you think me very—very cowardly if I told Madame Exe I could not sit today?’
