It was noon before the Japanese crew of the submarine were fetched off by the life-boat, and until this was done R.A.F. 21 had to stand by. Finally, with less than two gallons of fuel in her tanks, she brought the life-boat safely into Fisherton Harbour.

Dog-tired, his ears raw from exposure to the cold spray, his heels galled by the chafing of his sea-boots, Derek, having dismissed his crew, turned in and slept like a log, happy in the knowledge that another useful peace-time task had been successfully accomplished.

CHAPTER XXVIII

To the Sea-plane's Aid

"O Joy! O Rapture!" exclaimed John Kaye. "At last the mighty stream of demobilization is stayed, Daventry. Forty new hands have come in this morning. There will be a chance of commissioning some more boats. They're shouting for you in the Adjutant's office, old son."

"What for?" enquired Derek. "S'pose it's not in connection with our demob. or otherwise?"

For weeks Derek and Kaye had been more or less on tenterhooks. Both had applied for permanent commissions in the Marine Branch of the Royal Air Force, and, although their papers had been endorsed with a strong recommendation by the C.O., there appeared to be an endless and exasperating period of suspense.

"Unfortunately, no," replied Kaye. "They are overwhelmed with work in the Adjutant's office. The Adjy. hasn't had time even to play deck-quoits for the last three days. They want your aid, my festive bravo."

"Rotten luck!" growled Derek. "If there's anything I loathe it's fugging in an office. Had two half days at it at Torringham, I remember. Didn't feel fit for flying for nearly a week. Make the best of it, though, and the sooner the job's done the better I'll be pleased."
