"She's well down Channel by this time," soliloquised Dacres. "The rogue is safe for the time being, for the authorities dare not arrest him on a vessel flying Brazilian colours."

"What is the speed of the 'Maranhao'?" he asked of the English clerk in the firm's office.

"She's a fairly slow boat, sir," replied the man apologetically. "You see, she's running a relief trip, because the 'Alagoas' has broken her mainshaft. Twelve knots would be her average."

Dacres thanked him for the information and inquired when the "Maranhao" was likely to arrive at her destination—Pernambuco.

The man was unable to hazard an opinion, but in answer to further inquiries said that the distance from Southampton to Pernambuco was 3920 seamiles.

Allowing for a stop at Cape Verde Islands, Dacres came to the conclusion that the "Maranhao" would take at least thirteen and a half days to reach Pernambuco. This was reassuring, and having thanked the clerk for the trouble he had taken, he rejoined Callaghan and gave instructions to be whirled back to Whittinghame's retreat.

"We're too late," he announced as Vaughan Whittinghame came from the house to meet him. "Durango has contrived to get hold of the plans."

"Knowing the man I am not surprised," replied the owner of the "Meteor" calmly. "Have they collared him?"

"No; he's on the high seas. In another thirteen or fourteen days he'll land at Pernambuco—if he doesn't double on his tracks and disembark at Las Palmas or Cape Verde."

"He won't," said Whittinghame. "He'll get across to Naocuanha as sharp as he can possibly manage it. We'll try to nab him when he enters Valderian territory. It would be too risky to do so before."
