"Not much. The wires of the _Antinous_ have all been renewed--the Admiralty won't allow cables to be patched except at sea--but I haven't found out who played hanky-panky with them. It could not have been any one in the engine-room party, as none of them went near the place where the wires were cut. Besides, they were engineers, not electricians, and could have known nothing of the arrangements and disposition of the ship's wires. My man who worked with them is positive that they are a sound, good lot without a sea-lawyer or a pacifist among them; a gang of plain, honest tykes. So we are thrown back on the maintenance party, included in which were all sorts of ratings. Some of them are skilled in the electrical fittings--my own man with them is, for one--but we get the best accounts of all of them. They are long service men, cast for sea owing to various medical reasons, but perfectly efficient for harbour work. Among the officers of the ship is a R.N.R. lieutenant with a German name. I jumped to him, but the captain laughed. The man's father and grandfather were in the English merchant service, and though his people originally came from Saxony, he is no more German than we are ourselves. Besides, my experience is that an Englishman with an inherited German name is the very last man to have any truck with the enemy. He is too much ashamed of his forbears for one thing; and for another he is too dead set on living down his beastly name. So we will rule out the Lieutenant R.N.R. My own man, who is a petty officer R.N.V.R., and has worked on a lot of ships which have come in for repairs, says that the temper among the workmen in the yards is good now. It was ugly when dilution of labour first came in, but the wages are so high that all that trouble has settled down. I have had what you call sabotage in the shell and gun shops, but never yet in the King's ships. We have had every possible cutter of the wires on the mat before the Captain and me. We have looked into all their records, had their homes visited and their people questioned, inquired of their habits--Mr. Copplestone, here, knows what comes of drink--and found out how they spend their wages. Yet we have discovered nothing. It is the worst puzzle that I've struck. When and how the gun cable was cut I can't tell you, but whoever did it is much too clever to be about. He must have been exactly informed of the lie and use of the cables, had with him the proper tools, and used them in some fraction of a minute when he wasn't under the eye of my own man whose business it was to watch everybody and suspect everybody. I thought that I had schemed out a pretty thorough system; up to now it has worked fine. Whenever we have had the slightest reason to suspect any man, we have had him kept off the ship and watched. We have run down a lot of footling spies, too stupid to give us a minute's anxiety, but this man who cut the _Antinous_'s wires is of a different calibre altogether. He is AI, and
