“Engaged upon special service for the King!” exclaimed Lord Ashley, with a mocking laugh. “No; I regret to say that he was engaged upon very different service.”

“I don’t understand, Milord.”

“Then I will make myself perfectly clear,” said Lord Ashley, with emphasis. “Far from being engaged in His Majesty’s service that night, Captain Mortimer was conspiring with and aiding the enemies of the King.”

“Oh, monstrous!” exclaimed Dorothy with agitation. “I am convinced there is no truth in this.”

“I would that I could join you in this belief,” said Lord Ashley bitterly, “for the sake of the reputation of the army in general and of the Guards in particular. Unfortunately, the proofs in possession of His Majesty’s government are conclusive. Captain Mortimer has been led from the path of his duty to King and Government—has been led to his ruin—by yielding to temptations extended by the King’s enemies.”

“I am convinced there is some mistake,” replied Dorothy. There was a numb sensation in her brain and at her heart, yet she spoke the words bravely.

“Mistake!” repeated Lord Ashley. “Alas, no! The Government has in its possession proofs establishing Captain Mortimer’s connection with certain revolutionary factions to which he has given information and active aid. A search of his quarters subsequent to his disappearance revealed the presence of plans of fortifications and schedules as to the disposition of His Majesty’s forces of a most compromising character.”

Dorothy had recovered from the first shock of the Chancellor’s disclosures and all her senses were now alert.

“It does not seem probable,” she said slowly, “that a person about to disappear would leave all these compromising matters behind, when it would have been so easy to have destroyed them.”

“Ah!” retorted Lord Ashley quickly, “but this disappearance was not premeditated. The necessity for it arose suddenly and in an unforeseen manner.”
