"And a carriage-load of Spanish high mightiness between them; for that's the ambassador on his way to court," answered John Smith. "It's all up with our escapade if they get their eyes on us. We must bolt."

"How and whither?"

"Over the hedge and far away."

Spurring their horses, they broke through the low hedge that bordered the road-side, and galloped at a rapid pace across the fields beyond. The approaching party viewed this movement with lively suspicion.

"Who can they be?" queried Sir Lewis Lewknor, one of the noblemen.

His companion, who was no less a personage than Sir Henry Mainwaring, lieutenant of Dover Castle, looked questioningly after the fugitives.

"They are well mounted and have the start on us. We cannot overtake them," he muttered.

"You know them, then?" asked Lewknor.

"I have my doubt that two of them are the young Barneveldts, who have just tried to murder the Prince of Orange. They must be stopped and questioned."

He turned and bade one of his followers to ride back with all speed to Canterbury, and bid the magistrates to detain three suspicious travellers, who would soon reach that town. This done, the train moved on, Mainwaring satisfied that he had checked the runaways, whoever they were.
