"It has," agreed Entwistle. "We've been mixed up in a few together, haven't we? But to get back to the point. I'm curious to know how you managed to get a commission. You told me you were blind in one eye and deaf in one ear. How did you pass the doctor?" "I passed, or was passed by, three," replied Barcroft proudly. "Bluffed them absolutely. Merely a triumph of mind over matter. I learnt the letters on the sight-testing card off by heart. Perfectly simple, eh, what? I'm in the Marine Section, R.A.F., and incidentally I'm the senior officer in the depot in point of age. I'm on my way to Auldhaig to take some boats round to Sableridge--that's on the South Coast." "Not X-lighters, by any chance?" Barcroft stared. "Yes," he admitted. "What do you know about them?" Entwistle laughed. "Bet you twopence you won't find them at Auldhaig," he said. "More than that, you'll stand a chance of being arrested. There's been a fellow on the same sort of game, and that's why I'm here--to nab him on sight. By the by, how are Ponto and Nan?" "Going strong," replied Barcroft. "At the present moment they are assisting my crowd of merry wreckers to digest railway buffet sandwiches and bully beef. We'll go and find them." The two old chums walked down the platform. Just beyond the covered part was a large truck piled high with a miscellaneous assortment of kit-bags, blankets, sea-boots, oilskins, charts, and a pair of hand semaphore flags. Mounting guard over the luggage were Barcroft's two shaggy sheep-dogs. "They remember me," remarked Entwistle, as the animals began to wag their stumpy tails. "Of course," replied the R.A.F. officer. "But you wouldn't dare to lay a finger on that pile of kit." "I won't experiment," replied Entwistle. "Your dogs' teeth are just a trifle too formidable. When do you think you'll get back to Sableridge? I'm going down south in a fortnight or so, and I may run across you." "Look me up, then," replied Barcroft. "With decent luck I ought to get my five-knot convoy round in a fortnight, mines and contradictory Air Ministry orders permitting. And if I knock up against Captain Fennelburt I'll give him your chin-chin." "You won't," said Entwistle confidently--"at least, not under that name. But I hope to deny you that pleasure by having him under lock and key before many hours." The signal for the train's departure interrupted the conversation. Barcroft, having seen his crew into the train and the baggage in the van, entered a compartment followed by his two dogs--to bear the responsibility of navigating two of His Majesty's vessels, together with thousands of pounds worth of stores and a score of valuable lives, over six or seven hundred miles of mined waters; for which a grateful government paid him the magnificent sum of half a guinea a day. "And how is Mrs. Barcroft?" inquired Entwistle. "I ought, of course, to have inquired before." Peter Barcroft was lighting a cigarette.
