Lavendale was puzzled.

'You mean you're ready to start with your experiment, just as you are, like this?'

'Sure!' the little man answered, 'and you'd better get her going.'

They started off in silence. Once more Lavendale, as he glanced at the shabby little object by his side, began to lose confidence. As they swung round into Golder's Green he spoke again.

'What sort of a show are you going to give us?' he asked.

Mr. Hurn glanced at his watch.

'You'll know inside of an hour,' he replied.

Lavendale frowned. His protégé's appearance that morning was certainly not prepossessing. His collar showed distinct traces of its vicissitudes upon the previous day. His ugly, discoloured hands were ungloved; his boots were of some dull, indescribable material which seemed to have escaped the attentions of the valet; his flannel shirt was of the style and pattern displayed in Strand establishments which cater for the unæsthetic. He had discarded his hat for a black cloth cap and he had developed a habit of muttering to himself. Lavendale pressed the accelerator of his car and increased its pace.

'I suppose I've made a fool of myself,' he muttered.

They reached the open country and drew up in due time before the lodge gates of what seemed to be a very large estate. There was no sign as yet of the General. Mr. Hurn descended briskly and at once embarked upon a survey of the neighbourhood. Lavendale lit a cigarette and paused to watch the approach of a great limousine car rushing up the hill. It passed them in a cloud of dust,—he stood staring after it. Notwithstanding the closed windows, he had caught a glimpse of a face, of eyes gazing with strained intentness out on to his side of the road—the face of a woman convulsed with urgency—the woman who had played such queer havoc with his thoughts. Almost at the same moment there was a rasping voice in his ear.
