“No Prince of the Air would be mad enough to make the attempt,” replied Alan coldly. “Ask the captain of your scout-ship, and he will tell you that your city is surrounded; and I can tell you that four hundred guns are trained upon it at this moment, and that the firing of a shot, or the rising of any air-ship but my own from the ground, will be the signal for them all to be discharged. I need not tell your Majesty what the result of that would be.” Khalid recoiled with a cry that was almost one of fear. He knew instinctively that Alan was speaking the literal truth, without the confirmation given by the captain of the scout-ship. He saw, too, that Olga had deceived him, or at anyrate had been grievously mistaken, when she had said that the Aerians would not send a fleet after her squadron. They had done so, and so skilfully had its movements been ordered, that the city had been taken by surprise, and lay at its mercy. Brave as he was, the strange terrors of the situation sent a thrill of fear through his soul. There he stood, the proudest king on earth, on the roof of his palace, beneath the smiling sky of an Egyptian summer morning; and yet that smiling sky was charged with death and destruction a hundredfold greater than if the thunder-clouds were lowering on it, ready to hurl their lightnings upon the earth. He could see nothing but the blue heavens and the eastern sunlight shining over the roofs of his capital; and yet he knew that the man standing before him could, with a single signal, reduce the splendid city to heaps of shattered, shapeless ruins, and bury its inhabitants and its guests in one common tomb. Then what seemed to be a saving thought flashed through his mind, and he said, almost in a tone of banter-- “But in that case we should not die alone, unless you have taught those unsparing guns of yours to distinguish between friend and foe--the signal for our destruction would be the signal for yours as well.” “Even so!” replied Alan gravely. “That is a contingency which I have foreseen. Orloff Lossenski, tell his Majesty what my last orders to the fleet were.” The Russian stepped forward, and after saluting the Sultan said-- “I heard the orders given, Majesty, and they were to that effect. Friends and foes are to be destroyed alike, and nothing is to be left of Alexandria but its ruins. “I am also charged with a message to my mistress, the Tsarina, which tells her that if she does not leave within two hours her ships will be attacked in the city, and that, too, would be disaster; and if my words have still any weight with her I shall advise compliance with the order of the Council. Will your Majesty permit me to be conducted to my mistress in order that I may deliver my message in due form?”
