'Fortunately,' he was saying, 'I had with me a volume of Sh.e.l.ley, and one of my own little efforts. I had read Miss Keith the whole of the latter and much of the former before the chauffeur announced that it was once more possible--'

'Elsa,' said the wretched man, 'I had no idea--you don't think--'

She turned to him.

'I beg your pardon?' she said, very sweetly.

'I swear I didn't know--I mean, I'd forgotten--I mean--'

She wrinkled her forehead.

'I'm really afraid I don't understand.'

'I mean, about the car breaking down.'

'The car? Oh, yes. Yes, it broke down. We were delayed quite a little while. Mr Barstowe read me some of his poems. It was perfectly lovely.

I was quite sorry when Roberts told us we could go on again. But do you really mean to tell me, Mr Lambert, that you--'

And once more the world became all shoulder.

When the men trailed into the presence of the ladies for that brief seance on which etiquette insisted before permitting the stampede to the billiard-room, Elsa was not to be seen.

'Elsa?' said Mrs Keith in answer to Martin's question. 'She has gone to bed. The poor child has a headache. I am afraid she had a tiring day.'

There was an early start for the guns next morning, and as Elsa did not appear at breakfast Martin had to leave without seeing her. His shooting was even worse than it had been on the previous day.

It was not until late in the evening that the party returned to the house. Martin, on the way to his room, met Mrs Keith on the stairs. She appeared somewhat agitated.

'Oh, Martin,' she said. 'I'm so glad you're back. Have you seen anything of Elsa?'

'Elsa?'

'Wasn't she with the guns?'

'With the guns' said Martin, puzzled. 'No.'

'I have seen nothing of her all day. I'm getting worried. I can't think what can have happened to her. Are you sure she wasn't with the guns?'

'Absolutely certain. Didn't she come in to lunch?'

'No. Tom,' she said, as Mr Keith came up, 'I'm so worried about Elsa. I haven't seen her all day. I thought she must be out with the guns.'

Mr Keith was a man who had built up a large fortune mainly by consistently refusing to allow anything to agitate him. He carried this policy into private life.

'Wasn't she in at lunch?' he asked, placidly.

'I tell you I haven't seen her all day. She breakfasted in her room--'

'Late?'

'Yes. She was tired, poor girl.'

'If she breakfasted late,' said Mr Keith, 'she wouldn't need any lunch.

She's gone for a stroll somewhere.'

'Would you put back dinner, do you think?' inquired Mrs Keith, anxiously.

'I am not good at riddles,' said Mr Keith, comfortably, 'but I can answer that one. I would not put back dinner. I would not put back dinner for the King.'

Elsa did not come back for dinner. Nor was hers the only vacant place.

Mr Barstowe had also vanished. Even Mr Keith's calm was momentarily ruffled by this discovery. The poet was not a favourite of his--it was only reluctantly that he had consented to his being invited at all; and the presumption being that when two members of a house-party disappear simultaneously they are likely to be spending the time in each other's society, he was annoyed. Elsa was not the girl to make a fool of herself, of course, but--He was unwontedly silent at dinner.

Mrs Keith's anxiety displayed itself differently. She was frankly worried, and mentioned it. By the time the fish had been reached conversation at the table had fixed itself definitely on the one topic.

'It isn't the car this time, at any rate,' said Mr Keith. 'It hasn't been out today.'

'I can't understand it,' said Mrs Keith for the twentieth time. And that was the farthest point reached in the investigation of the mystery.

By the time dinner was over a spirit of unrest was abroad. The company sat about in uneasy groups. Snooker-pool was, if not forgotten, at any rate shelved. Somebody suggested search-parties, and one or two of the moustache-tuggers wandered rather aimlessly out into the darkness.

Martin was standing in the porch with Mr Keith when Keggs approached.

As his eyes lit on him, Martin was conscious of a sudden solidifying of the vague suspicion which had been forming in his mind. And yet that suspicion seemed so wild. How could Keggs, with the worst intentions, have had anything to do with this? He could not forcibly have abducted the missing pair and kept them under lock and key. He could not have stunned them and left them in a ditch. Nevertheless, looking at him standing there in his att.i.tude of deferential dignity, with the light from the open door shining on his bald head, Martin felt perfectly certain that he had in some mysterious fashion engineered the whole thing.

'Might I have a word, sir, if you are at leisure?'

'Well, Keggs?'

'Miss Elsa, sir.'

'Yes?'

Kegg's voice took on a sympathetic softness.

'It was not my place, sir, to make any remark while in the dining-room, but I could not 'elp but hoverhear the conversation. I gathered from remarks that was pa.s.sed that you was somewhat hat a loss to account for Miss Elsa's non-appearance, sir.'

Mr Keith laughed shortly.

'You gathered that, eh?'

Keggs bowed.

'I think, sir, that possibly I may be hable to throw light on the matter.'

'What!' cried Mr Keith. 'Great Scott, man! then why didn't you say so at the time? Where is she?'

'It was not my place, sir, to henter into the conversation of the dinner-table,' said the butler, with a touch of reproof. 'If I might speak now, sir?'

Mr Keith clutched at his forehead.
