studied the burning end of his expensive tobacco. “The term has been descretely imbedded in communications that refer to the correspondence with the scientists that have been contacted. I emphasize, in communications that refer to the correspondence with scientists, never in the correspondence with said scientists. And only obliquely.” “The term does not currently exist for any known manufacturing or fishing industry tool. It is an ominous term, ‘Water Hammer’, only because it is enigmatic. Nor can I deduce any link with the contacted scientists who have no military or weapon experience. I cannot fathom what could affect our Naval ships. “Could it imply experiments with warterborne weapons? “I cannot deduce unless I have information to deduce from,” he complained. I of course felt dissapointed, for I was now involved and I hated dead ends, or meandering leads that cannot be locked down. If my brother did not have enough information to work with, I doubted I could contribute anything to his ruminations. “Let me summarize what I had gathered from Jack’s briefings,” I began. “We know there is an international clandestine organization based upon Moriarty’s former crime organization. It has sinister intentions from the deaths it has inflicted while conducting its unknown purpose.” “Three that we know of, the third being Mr. Rawlings“ Mycroft interrupted. “We know that our Naval resources are under threat, because of the unveiled interest in their vulnerabilities.” I continued. “We have unwholesome correspondence with unwitting scientists by said malevolent organization. “The scientists’ expertise is in mechanical water effects, but we do not know the goal of gathering said knowledge. “We know that special contracts for particular technical equipment has been ordered by foreign agents. “Do we know where this equipment is being shipped to?” I inquired. “Confound it!” Mycroft exploded as he flung his cigar down on the floor across the room. He dug the report on the shrimp shipment invoice from his pocket. “No wonder I have retired! The damn shrimp were going to the same district that the heavy equipment has been delivered to! It is Wittgengold, deep in Germany!” A worried club steward looked in to the room to see what the outburst was, and if he could assist with anything. Mycroft composed himself, pointed to the discarded cigar and asked if the steward could clean it up and replace it with a new one and that some brandy be brought. “Are there any known munitions plants in that area?” I asked after the steward had left. “There was a small Krupp owned facility that is in an area of heavy industry.” Mycroft stated, “But we will have our agents look into any new large construction that has been done in the recent years. We will have them look out for anything that seems out of the ordinary or being closed to the public.” He paused while the club steward returned with cigar and a decanter of brandy and two glasses. He poured us both a shot and discretely departed. “What do we know of the heavy equipment that was delivered?” I asked, “What purpose is it used for?” “Water pumps and hydraulic piston components.” Mycroft responded. “ And we are not sure what function they would be used for.” “Since these were special ordered, “ I noted, “ and Germany has ironworks machinery production as good as England, why did they not have German industry supply the parts?” “That is also up for conjecture, Sherlock.” Mycroft commented. “What is significant about the water pumps?’ I asked. “They are specially designed to be radically high-pressure pumps,” Mycroft responded. “Anything unusual about the hydraulic piston components?” I inquired. “These were designed to be significantly smaller that say the pistons that drives a freight hauling locomotive, but with similar sturdiness.” He said. “So what manner of contraption are we dealing with,” I speculated, “a new type of weapon? A sea borne contrivance invented to attack our fleet? ” “I don’t believe that would be the case, Sherlock, “ Mycroft advised me. “These units as delivered would be too heavy and bulky to be used by anything short of a battleship. Battleships have racks of guns that can blast our Navy with tremendous shellings. I cannot conceive what enhancement this equipment could bring to bare on the standard artillery that currently exists. As you pointed out, Germany has tremendous skill in building massive artillery weapons, why order components from British factories?” “The scientists that were contacted, what was asked of them?” I continued my queries. “A lot of technical questions of fluid mechanics: transmission of wave forces under water, hindrance to motion of underwater objects, the dampening affect of water on propelled objects of various formed shapes and effects on propeller operation. The questions and replies had sufficient complex arithmetical context that we can infer the questioner has high skills in advanced mathematics. For, although the questions concerning hydraulics were asked as applied science, mathematic answers were given in its theoretical counterpart known as hydrodynamics, and responses were given in kind. Our own experts had to query other academic sources to understand the questions and the answers.” Mycroft replied.
