Beyond, stretched the largest sea-drome in Great Britain, a harbour within a harbour, surrounded by massive concrete walls. In the roughest weather, when even within the distant breakwater the Sound is turbulent, the sea-drome is calm as a duck-pond. Now it was like a sheet of polished silver, and resting on their great floats at their moorings were three gigantic air-liners, with electric launches and motor-boats plying between them and the landing-stages.
Right in the centre was the splendid Atlantis, graceful as a swan, by which Connie was to leave for the States in a few hours. She was surrounded by a swarm of boats no bigger than water-beetles from where I stood.
A bell rang, there was a rumbling sound, and from a tunnel just beneath me the car, with Lashmar in it, shot down to the water like a stone running down a house roof. As the car dwindled to a punt, a match-box, and finally a postage stamp, I heard the creak and swish of the semaphore behind me on the roof of the station. On the far side of the sea-drome was our Patrol Ship No. 1, stream-line fusilage, with the familiar red, white and blue line, snow-white planes, guns fore and aft, and twin propellers of phosphor bronze winking white-hot in the afternoon sun.
The semaphore was sighted in five seconds. I got a pair of glasses, and saw that the engines were already "ticking over" as Lashmar jumped into a launch and went over the pool, with a cream-white wake behind him and two ostrich plumes of spray six feet high at the bows. He was on board in less time than it takes to write it. I heard the faint throbbing of the four high-compression engines change to the drone of a hornet. No. 1 Patrol slid over the water until her floats lifted—lifted until they barely touched the surface, and she was clear. One clean spiral over Pinklecombe way, and then, as she mounted, she turned and was off over Rams Head like an arrow from a bow. Though I say it that shouldn't, my officers and men of the A.P. were just about as good as they're made!
There was a good three-quarters of an hour to spare, and the Royal Hotel was not four minutes away. After the recent excitements a cup of tea with Connie seemed just the thing. As I legged it over the Hoe, I realized that I might be very busy for some time, and, in consequence, late for dinner. I must tell my girl that something of great importance had happened, though, in any case, I was determined to see her off, come what might.
Then I remembered something. As Chief Commissioner I had absolute control over the airports of England in a time of crisis. In any case, it would be as well to, close the sea-drome in preparation for the May Flower's arrival. I should then be certain that no one could possibly get at Captain Pring before I could. And if I chose to detain even the Royal Mail for half an hour later on in the evening—under the circumstances!—no one would say me nay.
There is a telephone box in the hall of the Royal Hotel. In thirty seconds my orders were given, and not a living soul would enter or leave Plymouth sea-drome without my permission. Then I strolled into the winter gardens, where I found Connie sitting at a little table among tubs of azaleas and listening to the strains of a ladies' orchestra.
"I've half an hour and ten minutes exactly, darling," I said, putting my watch on the table and helping her to early strawberries. "Tell me when the time's up, and then I must rush away for an hour before we dine."
Straightway I forgot all about the Albatros, Captain Pring, and the mysterious armed ship in mid-Atlantic.
