"Provided he's fifty miles behind us, I won't worry my head about him," declared Sir Reginald. "I'm not particularly keen on coming in touch with him on a dark night. He might try his hand at another dirty trick."

[CHAPTER XXI--VON SINZIG'S BID FOR SAFETY]

Count Karl von Sinzig was in a particularly bad temper. He had just learned, by picking up various wireless messages, that "the cat was out of the bag." In other words, the discovery of the lost observation basket had landed him in a very awkward predicament.

He blamed everyone and everybody save himself. The luckless Unter-Leutnant, Hans Leutter, came in for a very bad time because he hadn't got rid of the second bomb. The petty officer, who had conscientiously seen that the bottle-screws securing the basket were properly made fast, was bullied and browbeaten because the basket was torn away. The rest of the crew, the makers of the airship, and every person having anything to do with the aerial contest also came in for abuse.

The count was also puzzled at not being able to intercept any messages from the "Golden Hind" after the one announcing her approach to Panama. Z64 had reported at Colon, when, according to the latest information, the British airship was hard on the heels of her German rival.

And now, almost the final straw, came the general wireless message declaring that Z64 was proscribed and liable to be detained should she touch at any place belonging to either of the entente nations.

Fosterdyke had accurately gauged his rival's intentions. The knowledge that his guilty secret was out compelled von Sinzig to change his plans and make for Teneriffe, whence, having replenished fuel, he ought to be easily able to complete the last stage of the round the world voyage.

When about 300 miles to the westward of the Canaries, but farther to the north than von Sinzig hoped to be, owing to a strong side-drift, Z64 encountered a violent storm. In order to try to avoid the worst of the terrific wind and rain, the airship began to ascend, hoping to find better conditions in the rarefied atmosphere.

Z64 was ascending obliquely under the action of her huge horizontal rudders and was passing through a dense cloud when a vivid flash of lightning, followed almost immediately by a deafening crash of thunder, appeared to penetrate the airship through and through.

Almost every man on board shouted with terror. They were fully convinced that the hydrogen had ignited. There was a frantic rush for the life-saving parachutes, until Unter-Leutnant Hans Leutter reassured the panic-stricken crew with the information that the gas-bag had not taken fire.
