The three set off, the landlord uttering many groans and lamentations as he jolted in his saddle. Harry did not address him; he had too much to think of. If, as Aglionby's messenger had said, there were spies in Urach and around, it was likely that the entrance of three riders into the town at so late an hour would be noticed, and might awaken suspicion. Harry's wish was not merely to foil the ambuscade, but to turn the tables on the ambuscaders. As he rode he decided what to do.

"Max," he said, riding alongside of the man where a difficult part of the track caused a slackening of the pace; "Max, tell me when we come within about half a mile of the town; we will halt there."

"We leave the hills and strike the road at that distance, Monsieur."

"Very well; we will stop before we reach the road."

It was two o'clock in the morning when the three riders came to a halt within a little dell concealed from the road by an intervening hillock.

"Remain here with the landlord and my horse, Max," said Harry. "I am going on foot to the town."

At the gate-house he gave the password and was at once admitted. He went to the lodging of the lieutenant of the guard, woke him, and told him in a few words what he had discovered.

"Mon Dieu!" cried the lieutenant, "you are just in time. The prince decided last night to hasten his going; he sets off at four. He will have to remain here, or go back, for his escort are no match for these brigands, even with our burgher guard, who in any case are not permitted to leave the town. The prince must either wait here until he can get a force from Prince Louis of Baden, or try another road."

"The roads are watched. But I think the prince had better carry out his original intention and leave here at five."

"But he will certainly be captured."
