Kennedy called the waiter for a drink, and carelessly asked what was in progress.

“The ship—the Oakham—came in the day before yesterday, sir,” the man replied. “There’s a party on board this evening, they say—our Mayor and corporation, and all the rest.”

Ella exchanged glances with her lover. She recollected that khaki-covered despatch-box. Had her father brought with him that terrible death-dealing machine which he and Nystrom had constructed with such accursed ingenuity?

The hotel was deserted, as east coast hotels within the danger zone usually were in those war days, remaining open only for the occasional traveller and for the continuity of its licence. The great revue star had sent a telegram to her manager, asking that her understudy should play that night, and the devoted pair now stood side by side watching how, in the rapidly falling night, the twinkling electric lights on board the fine British cruiser became more clearly marked against the grey background of stormy sea and sky.

“I wonder what their game can really be?” remarked the young flying-officer reflectively as, alone with Ella, his strong arm crept slowly around her neat waist.

From where they stood they were afforded a wide view of the broad road which led from the town down to the landing-stage, from which the cruiser’s steam pinnace and picket-boat were speeding to and fro between ship and shore. A dozen or so smart motor-cars had descended the road, conveying the guests of the captain and officers who, after their long and unrelaxing vigil in the North Sea, certainly deserved a little recreation. Then, as the twilight deepened and the stars began to shine out over the bay, it was seen that the procession of guests had at last ended.

“I think, Ella, that we might, perhaps, go down to the landing-stage,” said Kennedy at last—“if you are not too tired, dear.”

“Tired? Why, of course not,” she laughed, and after he had helped her on with her coat, they both went out, passing down to the harbour by another road.

For fully an hour they idled about in the darkness, watching the swift brass-funnelled pinnace which, so spick and span, and commanded by a smart lad fresh from Osborne, was making the journey regularly between ship and quay. Away in the darkness the lights on the cruiser’s quarter-deck reflected into the sea, while ever and anon the high-up masthead signal-lamp winked in Morse code to the coastguard station five miles distant across the bay.

While they were watching, the pinnace came in again, whereupon the smart figure of a naval officer in his topcoat appeared within the zone of light, and descended the steps, shouting in an interrogative tone:
