"Ah, yes; but now? Supposing the wire is insufficient to take the strain?"
"It will bear thrice our total weight," replied the first speaker, "frail though it looks. No fear of that breaking. It is that highly-charged electric cable that worries me. We must have landed nearer to it than we should have done, yet it looks further away on the map."
The fellow completed his difficult task of lifting Norton into the interior of the covered-in car—the observation room of a Zeppelin floating motionless five hundred feet or so overhead.
The commander of the giant aircraft had successfully carried out a daring manoeuvre with the ultimate object of taking prisoner the man on whom his imperial master the "All-Highest" had set a price for his capture. Taking advantage of an almost imperceptible breeze and knowing his position to an almost dead certainty by means of exact cross-bearings afforded by three reservoirs, conspicuous even in the darkness, he had caused to be lowered the aluminium observation car.
In flight this contrivance is slung close under the after part of the Zeppelin, but when necessary it can be lowered by means of a fine but enormously strong flexible steel wire to a maximum distance of two thousand feet beneath the giant envelope. Thus it is possible for a Zeppelin to remain hidden in a bank of clouds and lower the observation car to within a few hundred feet of the ground. Its comparatively small size and inconspicuous colour would render it invisible even at that short distance, and give the observer an uninterrupted view of the country. By means of a telephone he could then communicate with the commander of the airship and indicate the objects singled out for attack.
On this occasion the aluminium box was lowered till it touched the ground. The two men purposely told off for the work in hand had anchored the car, thereby keeping the Zeppelin stationary also. In the event of a surprise the airship's crew would unhesitatingly sever the wire and leave the car and their two comrades to their fate.
And now most of this particular enterprise had been carried out. The supposed object of their attentions lay gagged and bound within the aluminium cage. All that remained to be done was to break out the grapnel and signal to the men in the Zeppelin to wind in the steel cable.
"All ready?" enquired Pfeil through the telephone. "Good! When I give the signal will you forge ahead to the north-east? Why? Because we are much too close to the high tension cable which Herr Leutnant knows of."
He leant through an aperture in the side of the cradle and listened intently. At the first sound of the airship's propellers he jerked a tripping-line smartly. The fluke of the grapnel folded as he did so, and the car, no longer held captive, slid jerkily over the grass.
"Up!" telephoned the German.
