'Is it? Yes! No, it isn't,' said Peter, going over to the window. 'But I 'll tell you who it is, though! It's Dunbar, and he 's got a commissario of police with him! Now, what in the name of wonder do they want here?'

The two riders dismounted at the gate and came up the little path through the garden to the door. They walked stiffly, as though they had ridden for a long time, and their horses, tethered by the gate, looked used up and tired.

Dunbar hardly paused to shake hands. 'Look here,' he said, 'E. W. Smith is here, and he 's wanted!'

CHAPTER XV

'First of all,' said Peter, 'who is E. W. Smith, and why the dickens should you imagine he is here?'

Dunbar gave him a quick look. 'Is any one here?' he asked.

'No one but Ross and Christopherson and myself,' said Peter. 'Purvis was here, but he started for Buenos Ayres last night, and I have no idea where he is now. I saw the train start from the station at Taco, but he was not in it.'

'Purvis is in a tight place,' said Dunbar dryly.

Ross, hearing voices in the drawing-room, wakened up, and now appeared with ruffled hair and still clad in his sleeping-suit. He suggested refreshments, and sat down to hear what Dunbar had to say.
