llo! Is that Christopher Berkeley?' said a voice from above.

Kit staggered, and stood speechless. It was the Doctor's voice; there was
no doubt about that. But how came he to be driving towards Crofts instead
of away from it? His sudden appearance was so remarkable that the boy's
head felt in a whirl.

'I--I thought----' he faltered.

The Doctor gave a quiet laugh, and climbed down from his seat.

'You thought I was green enough for anything, didn't you?' he observed.
'Just stand by the animal, will you, while I get out of my coat?'

Kit obeyed mechanically. Everything had turned so topsy-turvy all at once,
that it seemed no more extraordinary for him to be doing meekly what the
Doctor told him than it was for the Doctor to be struggling out of his
greatcoat just as the rain was beginning to come on again.

'Then--then you didn't go to Bobby Hearne's aunt, after all?' he inquired
stupidly.

'Not much!' answered the Doctor, with another short laugh. He had got his
coat off by this time, and he held it out to Christopher peremptorily.

'Do you want to keep me here all night?' cried Dr. Hurst, impatiently;
and as Kit still hesitated, he wrapped the coat quickly round him and

'Aren't you going to ask after your sister?' he demanded.

Kit started. 'I was afraid you'd rag me for it,' he muttered awkwardly.

The Doctor flicked the horse with his whip. 'Sorry you think me such a
brute,' he said shortly. He flicked the horse again, and played it a
moment or two, as it tossed its head and jumped about. 'I don't think
it's anything serious,' he went on. 'I gave her a soothing draught, and
everything depends on the state in which she wakes up. But I think she'll
be all right.'

The relief at Kit's heart nearly choked him. 'Did Jill tell you it was
my fault?' he asked after a while.

'I gathered as much,' said Dr. Hurst. 'You mustn't excite her any more,
you know, or I won't answer for the consequences. What was it all about,
eh?'

He was evidently making a gigantic effort to be amiable, and Christopher
felt he owed him something in return. Besides, it was a
