In my case, it was not a question of a license to fly a ship but of my right to be in Zodanga at all; so my approach to the city was not without its spice of adventure.

At last the city wall lay almost directly beneath me; and I was congratulating myself upon my good fortune, as there was no patrol boat in sight; but I had congratulated myself too soon, for almost immediately there appeared from behind a lofty tower one of those swift little cruisers that are commonly used in all Martian cities for patrol service, and it was headed directly toward me.

I was moving slowly, so as not to attract unfavorable attention; but I can assure you that my mind was working rapidly. The one-man scout flier that I was using is very fast, and I might easily have turned and outdistanced the patrol boat; however, there were two very important objections to such a plan. One was that, unquestionably, the patrol boat would immediately open fire on me with the chances excellent that they would bring me down. The other was, that should I escape, it would be practically impossible for me to enter the city again in this way, as my boat would be marked; and the entire patrol system would be on the lookout for it.

The cruiser was steadily approaching me, and I was preparing to bluff my way through with a cock-and-bull story of having been long absent from Zodanga and having lost my papers while I was away. The best that I could hope from this was that I should merely be fined for not having my papers, and as I was well supplied with money, such a solution of my difficulties would be a most welcome one.

This, however, was a very slim hope, as it was almost a foregone conclusion that they would insist upon knowing who my sponsor was at the time my lost papers were issued; and without a sponsor I would be in a bad way.

Just as they got within hailing distance, and I was sure that they were about to order me to stop, I heard a loud crash above me; and glancing up, I saw two small ships in collision. I could see the officer in command of the patrol boat plainly now; and as I glanced at him, I saw him looking up. He barked a short command; the nose of the patrol boat was elevated; and it circled rapidly upward, its attention diverted from me by a matter of vastly greater importance.

While it was thus engaged, I slipped quietly on into the city of Zodanga.

At the time, many years ago, that Zodanga was looted by the green hordes of Thark, it had been almost completely razed. It was the old city with which I had been most familiar, and I had visited the rebuilt Zodanga upon but one or two occasions since.

Cruising idly about, I finally found that for which I sought—an unpretentious public hangar in a shabby quarter of the city. There are quarters in every city with which I am familiar where one may go without being subjected to curious questioning, so long as one does not run afoul of the officers of the law. This hangar and this quarter of Zodanga looked such a place to me.
