"Hullo! Is that you, Dastral?"

"Yes. How are you, Garner, old man?"

"But hang it, how came you to ring me up? I should dearly love to see you, but I've my hands full to-night. We received 'Air Raid Action' half an hour ago. Several hostile airships have crossed the east coast, and are making for the metropolis, so I cannot stay now. Come and see me in the morning, do, old man. Eh, what's that you say?"

"Haven't you a spare machine you could let me try if I came over there by fast motor at once?"

"Hullo! hullo! All the machines are out with the men standing by, ready to go up at the first tip, except--let me see now--we've got a new fast 'Buckstead Bullet' here, which none of the men are very familiar with yet. There's that. Come if you like, old fellow. It's a bit irregular, but if there should happen to be a big attack on London, and the case warrants it, I see no reason why you shouldn't try the blamed thing. It's a single-seater, only just in from the makers, and a devil of a whizzer as well as a first class climber!"

"Right-o! I'm coming straight away!" cried Dastral, waiting to hear no more, and banging down the receiver.

The next minute he was outside on the pavement, forgetting all about Tim, the settlement of the bill, and everything else. Tim, however, who had heard part of the message, had already paid the bill and got outside, where he had hailed a taxi, determined not to be left behind, for his quick intuitive mind had told him which way the wind was blowing. He had had a hard job to secure the vehicle, for there had been a great demand for the same, but he had whispered Dastral's name to the chauffeur and had agreed to foot the bill however big it might be, although he had only three half-crowns left in his pocket after squaring the bill indoors. That did not bother him at all, however. Here was a chance of rendering some service, however small, to the nation at large, for he felt convinced that if only Dastral could have a chance he would bring down half a dozen raiders.

Immediately, therefore, Dastral appeared at the doorway he shouted:

"This way, Dastral, this way. Quick!"

"What the deuce----"
