'Besides, on the steamer,' said Toffy, 'he could be easily caught.' 'Yes,' said Dunbar, 'if he knows that we want to catch him, which he doesn't. He is afraid of the people at La Dorada now; but he is probably unaware of the warm welcome that awaits him in Buenos Ayres.' Dunbar went to the door again to see if there was any sign of his messenger returning from the telegraph office. The sun was flaming to westward, and Hopwood had moved the dinner-table out into the patio, and was setting dinner there. 'He will do the unexpected thing,' said Ross at last. 'If Purvis ever says he is going to sit up late I know that is the one night of the week he will go to bed early.' They went out into the patio, and Ross swizzled a cocktail, and they fell to eating dinner; but Dunbar was looking at his watch from time to time, and then turning his glance eastward to the track where his messenger might appear. It was an odd thing, and one of which they were all unaware, that even a slight noise made each man raise his head alertly for a moment as though he might expect an attack. The sun went down, and still no messenger appeared. They sat down to play bridge in the little drawing-room, and pretended to be interested in the fall of the cards. 'That must be my telegram now,' said Dunbar, starting to his feet as a horse's hoofs were plainly heard in the stillness of the solitary camp. 'Well, I 'm damned,' he said. He held the flimsy paper close to his near-sighted eyes, and read the message to the other men sitting at the table: 'Smith, or Purvis, at present on board his own steamer in midstream opposite La Dorada. Fully armed and alone. Crew have left, and peons in revolt. A detachment of police proceeds by train to Taco to-night. Join them there and await instructions.' 'I thought he would stick to the steamer,' said Ross at last. 'And probably,' said Dunbar, 'he is as safe there as anywhere he can be. He can't work his boat without a crew, but if he is armed he will be able to defend himself even if he is attacked. I don't know how many boats there were at La Dorada, but I would lay my life that Purvis took the precaution of sending them adrift or wrecking them before he got away.' 'What is to be the next move?' said Peter. 'I suppose we shall have to ride down to Taco to-night,' said Dunbar. 'Yon man,' he finished, in his nonchalant voice, 'has given me a good bit of trouble in his time.' 'It seems to me,' said Ross, 'that you can't touch any business connected with Purvis without handling a pretty unsavoury thing.' 'Now, I 'll tell you an odd thing,' said Dunbar. 'I have had to make some pretty close inquiries about Purvis since I have been on his track, and you will probably not believe it if I tell you that by birth he is a gentleman.' 'He behaves like one,' said Ross shortly.
