II

Burton returned to the creek, boarded his flying-boat, and was soon skimming across country on the fifteen-mile flight to Chatham.

He had been Micklewright's fag at school, and the two had remained close friends ever since. Micklewright, after carrying all before him at Cambridge, devoted himself to research, and particularly to the study of explosives. To avoid the risk of shattering a neighbourhood, he had built his laboratory on the Luddenham Marshes, putting up the picturesque little cottage close at hand for his residence. There he lived attended only by an old woman, who often assured him that no one else would be content to stay in so dreary a spot. He had wished Burton, when he left school, to join him as assistant: but the younger fellow had no love for "stinks," and threw in his lot with a firm of aeroplane builders. Their factory being on the Isle of Sheppey, within a few miles of Micklewright's laboratory, the two friends saw each other pretty frequently; and when Burton started a flying-boat of his own, he often invited himself to spend a week-end with Micklewright, and took him for long flights for the good of his health, as he said: "an antidote to your poisonous stenches, old man."

Burton was so much accustomed to voyage in the air that he had ceased to pay much attention to the ordinary scenes on the earth beneath him. But he had completed nearly a third of his course when his eye was momentarily arrested by the sight of two motor-cycles, rapidly crossing the railway bridge at Snipeshill. To one of them was attached a side car, apparently occupied. Motor-cycles were frequently to be seen along the Canterbury road, but Burton was struck with a passing wonder that these cyclists had quitted the highway, and were careering along a road that led to no place of either interest or importance. If they were exploring they would soon realise that they had wasted their time, for the by-road rejoined the main road a few miles further east.

On arriving at Chatham, Burton did not descend near the cemetery, as he might have done with his landing chassis, but passed over the town and alighted in the Medway opposite the "Sun" pier. Thence he made his way to the address in the High Street given him by Micklewright. He was annoyed when he found the place closed.

"Just like old Pickles!" he thought. "He forgot it's Saturday." But, loth to have made his journey for nothing, he inquired for the private residence of the proprietor of the store, and luckily finding him at home, made known the object of his visit.

"I'm sorry I shall have to ask you to wait, sir," said the man. "The place is locked up, as you saw; my men have gone home, and I've an engagement that will keep me for an hour or so; perhaps I could send it over--some time this evening?"

"No, I'd better wait. Dr. Micklewright wants the stuff as soon as possible. When will it be ready?"

"If you'll be at the store at three o'clock I will have it ready packed."

It was now nearly two.
