cups of tea into the yard, for we were far too anxious and busy to think of the afternoon gossip. The days were lengthening, of course, but we found them all too short. This final experiment that we were undertaking would prove whether, after all, we had any effective defence against the terror of the night—or not.
Try how I would, I could not put entirely away from myself the growing suspicion that, if spies had been so watchful, they would now be increasingly eager and ingenious in their endeavour to combat us. Once I laughed at those who told us there were German spies about us—I denounced them as scaremongers. But hard facts, shown to us in black and white, shown to us in prosecutions and actual executions of spies, had convinced me—as they must have convinced every Briton unless he were a pro-German or a lunatic—that dastardly secret agents existed even in the most unsuspected quarters, and that the Invisible Hand had been responsible for many a disaster to the British arms on land and at sea.
Would that Hand still bring disaster upon myself?
Daylight faded—and quickly. The evening was calm and clear, with an orange glow of sunset in the west.
All was in readiness. My machine, with its big dual engines, its searchlight, its dynamo, and that most deadly apparatus contained in the brown deal box, stood in the yard running like clockwork, all its controls in order, every strainer taut, every nut locked, and the wooden petrol-container filled.
