Lord Ashley’s next visitor was Captain Bagley.

“Captain,” said Lord Ashley abruptly, “you are called upon for a certain service of state, such as occasionally arises in the affairs of government. Upon your faithful and discreet performance of that service depends the matter of future favors and promotion.”

Captain Bagley bowed low, maintaining a respectful silence.

“Your orders are these,” continued Lord Ashley: “At fifteen o’clock to-day you will proceed to a point in the park where you can observe the summer-house upon Antler Hill. Conceal yourself from observation among the trees, or bushes. At about fifteen and three-quarters o’clock you will observe an escaped prisoner walking along the Stag Walk toward Antler Hill. That escaped prisoner will be Captain Stanley Mortimer. Permit him to proceed to Antler Hill, where he will be met by a certain personage, whom it is not your concern to recognize. Should he leave Antler Hill in company with that personage, you will permit him to go unhindered on his way. Should he leave alone and seek to return in the direction of the military quarters, or the palace, then your instructions are different. Do you understand thus far?”

“Fully, Milord!” answered Captain Bagley.

“Should he start to return,” continued Lord Ashley, “he cannot possibly do so until sixteen o’clock, or later. The moment sixteen o’clock has sounded and you find him upon the return journey, you will come upon him and shoot him dead. You understand?”

“Fully!” repeated Captain Bagley.

“Your excuse will be that he was an escaping prisoner and that your life was in danger. For the rest, you may look to me to protect you fully in your action.”

Captain Bagley bowed.

“You notice here,” continued Lord Ashley, pointing to an instrument beside the wall, with a large reflector above it, “the sigmagraph. As you know, it is used to signal the guard house to turn out a guard of honor and salute when some visitor of rank is about to leave the Chancellerie. Five flashes of the sigmagraph are the signal for the guard; any smaller number are mere test signals. At sixteen o’clock, precisely to the last stroke, you will turn your eyes to the signal receiver upon the roof of the military quarters. Should no signal come, you will follow out the instructions given. Should you notice three flashes from the sigmagraph, then your orders are cancelled and the escaping prisoner is to be permitted to pass unhindered. Are these instructions clear to you?”
