'Frau Nieberlein is not with you this morning?' she asked pleasantly, as we shuffled side by side into the princely apartments.

'She is resting. She had rather a bad night.'

'Nerves, of course.'

'No, ghosts.'

'Ghosts?'

'It's the same thing,' said Ambrose. 'Is it not, sir?' he asked amiably of the man in spectacles.

'Perhaps,' said the man in spectacles cautiously.

'But not a real ghost?' asked Mrs. Harvey-Browne, interested.

'I believe the great point about a ghost is that it never is real.'

'The bishop doesn't believe in them either. But I—I really hardly know. One hears such strange tales. The wife of one of the clergy of our diocese believes quite firmly in them. She is a vegetarian, and of course she eats a great many vegetables, and then she sees ghosts.'
