"Catch her; stop her--oh--oh!" Curberry's grip loosened, and he rolled over with a moan. Whether he was dead or alive, Dan did not wait to see. Every moment was precious, if he intended to stay the flight of Queen Beelzebub. The terrified men came to assist their dying master, and more servants, attracted by the noise, poured in at the library door. A backward glance showed Dan that Curberry was being attended to, and then he sped along the terrace towards the lawn at the side of the house. Here he arrived, just a moment too late, for already the aeroplane was spinning along the turf, with Queen Beelzebub in the pilot's seat. Like the wicked fairy of nursery tale, she was escaping in her dragon-car, and even in that hour of success she did not utter a sound. Silent and menacing she mounted into the air, and Halliday dashed forward with a cry of rage as she lifted above his reach. There was not a moment to be lost, and without another glance, he raced down the avenue, and made for the entrance gates. Queen Beelzebub might make for her lair in Hillshire, or it might be that she would cross the Channel to seek safety on the Continent; but, wherever she went, Dan intended to follow. She would not escape him this time, and he flew like an arrow from the bow across from the open space outside the park, to where his man still stood guard by his own machine. The little crowd around had their faces turned heavenward, and were shouting at the sight of the biplane, now dwindling to a black dot, as it receded swiftly from Blackheath. Dan felt a throb of satisfaction as he saw that Queen Beelzebub was making for the north. "Out of the way; out of the way," gasped the young man, charging through the throng, and it scattered at his approach, "let her go, let her go!" and he sprang into the pilot's seat to start the engine.
