The Classic Mystery Collection - Arthur Conan Doyle [1033]
Now Memmert was part of the outer rampart; its tapering sickle of sand directly commanded the eastern breach; it _must_ be connected with the defence of this breach. No more admirable base could be imagined; self-contained and isolated, yet sheltered, accessible--better than Juist and Borkum. And supposing it were desired to shroud the nature of the work in absolute secrecy, what a pretext lay to hand in the wreck and its buried bullion, which lay in the offing opposite the fairway!
On Memmert was the depot for the salvage operations. Salvage work, with its dredging and diving, offered precisely the disguise that was needed. It was submarine, and so are some of the most important defences of ports, mines, and dirigible torpedoes. All the details of the story were suggestive: the 'small local company'; the 'engineer from Bremen' (who, I wondered, was he?); the few shares held by von Brüning, enough to explain his visits; the stores and gear coming from Wilhelmshaven, a naval dockyard.
Try as I would I could not stir Davies's imagination as mine was stirred. He was bent on only seeing the objections, which, of course, were numerous enough. Could secrecy be ensured under pretext of salving a wreck? It must be a secret shared by many--divers, crews of tugs, employees of all sorts. I answered that trade secrets are often preserved under no less difficult conditions, and why not imperial secrets?
'Why the Ems and not the Elbe?' he asked.
'Perhaps,' I replied, 'the Elbe, too, holds similar mysteries.' Neuerk Island might, for all we knew, be another Memmert; when cruising in that region we had had no eyes for such things, absorbed in a preconceived theory of our own. Besides, we must not take ourselves too seriously. We were amateurs, not experts in coast defence, and on such vague grounds to fastidiously reject a clue which went so far as this one was to quarrel with our luck. There was a disheartening corollary to this latter argument that in my new-born zeal I shut my eyes to. As amateurs, were we capable of using our clue and gaining exact knowledge of the defences in question? Davies, I knew, felt this strongly, and I think it accounted for his lukewarm view of Memmert more than he was aware. He clung more obstinately than ever to his 'channel theory', conscious that it offered the one sort of opportunity of which with his peculiar gifts he was able to take advantage. He admitted, however, that it was under a cloud at present, for if knowledge of the coastwise navigation were a crime in itself we should scarcely be sitting here now. 'It's something to do with it, anyhow!' he persisted.

MEMMERT gripped me, then, to the exclusion of a rival notion which had given me no little perplexity during the conversation with von Brüning. His reiterated advice that we should lose no time in picking up our anchor
