The daily papers gave no further definite information about the unknown airship. It appeared to have escaped notice for nearly three weeks, although during that interval there were several unauthenticated accounts that it had been "spotted." Many reports turned out to be deliberate hoaxes, while in one instance a company of Royal Engineers at Portsmouth turned out with a searchlight, only to find that the "airship" reported by a belated and slightly inebriated clubman was a large telephone cable spanning the narrow roadway between two lofty blocks of buildings.

Finding he had plenty of time on his hands Dacres decided to walk to Waterloo. After an absence from Town he had a strong desire to see some of the familiar haunts, so after walking along Piccadilly and thence to Trafalgar Square, he turned down Northumberland Avenue. Under existing circumstances he gave the Admiralty buildings a wide berth, for he had no inclination to come in contact with any of his former brother-officers.

Just as he was passing the Metropole, Dacres nearly collided with a powerfully-built, athletic-looking man who looked anything between twenty and thirty years of age.

In the midst of mutual apologies the stranger suddenly exclaimed:—

"Why, bless my soul, what are you doing here, Dacres?"

"Hythe, by Jove!" ejaculated Dacres.

"Right you are, old man. You haven't altered much since I saw you last. Let me see, that was when we paid off in the old 'Cornwall' in 1914. But we needn't stand here; come to my club—it's only a few minutes' walk."

Arnold Hythe was in more respects than one a fortunate individual. In recognition of his services in connexion with the submarine "Aphrodite"—now the prototype of the British "M" class—he had been promoted to the rank of Inspecting Commander of Submarines after less than a year's service as lieutenant. This was creating a precedent, but circumstances warranted it, and when the unusual appointment was announced, the shoals of congratulatory telegrams that poured in from his brother-officers showed that in this case there was little or no grumbling at Hythe's well-deserved promotion.

"Dacres, old man, I am awfully sorry," remarked Hythe with genuine concern when Dacres had told his story. "I cannot imagine what possessed old Maynebrace to take such drastic measures. Of course I had a lot to do with him when he was Admiral Superintendent at Portsmouth, and, personally, I found him quite a genial old fellow. Possibly his being sent to sea from a dockyard commission without being promoted to Vice-Admiral may have soured his temper a bit. By the by, what are your plans?"

"Nothing definite at present. Ultimately I hope to do something in the way of flying. Always had an inclination in that direction."
