'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.'
