There was not a second to spare. Casteno shot at me a look of mingled entreaty and command to leave the frenzied professor to do his worst. The persons we had to fear were not, he motioned, in that tent at all but outside, scouring the grounds for medical assistance, and spreading everywhere news of our wonderful appearance out of the rain-clouds. Only let them hear this maniac's wild cries for assistance and they would hasten back to us, and then all hope, all chance of escape, for either of us would be cut off. Nevertheless, I thought of Doris lying there so weak, helpless, and friendless; and I hesitated. I felt I had already stifled Love so often for Duty that I could repress it no longer. Indeed, I took a step in her direction to make myself known to her, but, misconceiving my object, thinking I had no idea but one--to flee--Leopardi seized me in a grip of iron. "You shall not go," he panted--"never! You are a thief, and you shall pay for your crime." His touch, however, was quite enough. What Casteno had failed to accomplish it brought about in a flash. All the hot, strenuous instincts of my manhood rose in rebellion at this degradation. "You are mad," I hissed, and with one huge effort I sprang on the scientist and, catching him by the middle, whirled him over my head and sent him crashing a moment later on to some grain bags that stood piled up in a corner. As I did so his wig fell off and with it his beard, and I staggered backward in amazement. The so-called expert from the Meteorological Office was, as the Spaniard had contended, a spy--perhaps sent by the Foreign Office, for it was a man we instantly recognised--no other than Colonel Napier himself. Personally, I would have stood my ground then and defied him; but Casteno was too quick for me. As I reeled back breathless from the impact he caught me by the shoulder and with a quick turn twisted me through the narrow door of the barn. "This is no time for heroics, Glynn," he whispered. "We have won. Now let us be off." And he doubled behind some other buildings and then dived headlong into a clump of bushes, through which he wriggled his way on hands and knees like a snake. Almost instinctively I followed him, for on the still summer breeze I could hear Colonel Napier's voice raised in angry shouts, the thunder of hurrying feet, and all the mysterious sounds and movements which betokened that at last the crowd had taken alarm, and that an organised pursuit of us could, at the most now, be only a matter of a few seconds. The branches tore our clothes and made sad havoc of our disguises, but this last accident proved a blessing in disguise, for it made us stop at a pond and restore to our faces their natural resemblance.
