Murder Mysteries for the Holiday Season. Джером К. Джером

"I wish to add a few words to the remarks of our learned president," said a small man, rising up from among the first line of the company. "I have placed upon the table such materials as I could lay my hands upon in order that the learned doctor may be able to illustrate his discourse by any experiments which he may think appropriate. I may warn him, in conclusion, to speak somewhat slowly and distinctly, as some of his hearers are but imperfectly acquainted with the German language."
Here was my old luck again with a vengeance! At a time when Walderich and every gay dog in Berlin were snoring peacefully in their beds, I—I, Doctor Otto von Spee, the modest man of science—was lecturing to a murderous secret organisation—for my audience could be nothing else—and teaching them to forge the weapons with which they were to attack society and everything which should be treasured and revered. And on such a night as this too! Should I, then, put it in their power to convert a house into an arsenal, to destroy the stability of the Fatherland, and even perhaps attempt the life of my beloved kaiser? Never! I swore it—never!
Most small men who wear spectacles are obstinate. I am a small man with spectacles, and I was no exception to the rule. I clenched my teeth, and felt that ruat ccelum, never a word should pass my lips that might be of any help to them. I should not refuse to lecture, but I was determined to avoid those very points upon which they desired to be instructed.
I was not allowed much time for meditation. An ominous murmur among the audience, and a shuffling of feet upon the floor, betokened their impatience. I must say, however, that many of them seemed actuated with rather kindly feelings towards me, more particularly one stoutish individual of a well-marked Celtic type, who, not content with smiling all over his florid countenance, waved his arms occasionally in motions intended to indicate sympathy and inspire confidence.
I stepped up to the table, which was covered all over with such objects as were thought to have a bearing upon my subject. Some of them were rather curious—a lump of salt, an iron teapot, part of the broken axle of a wheel, and a large pair of kitchen bellows. Others were more appropriate. There was a piece of guncotton which could not have weighed less than a couple of pounds, coarse cotton, starch, various acids, a Bunsen burner, tubes of fulminate of mercury, some dynamite powder, and a large pitcher of water. There was also a carafe and tumbler for my own use, should I feel so disposed.
"Meine herren," I began, with perhaps a slight quaver in my voice, "we have met here tonight for the purpose of studying dynamite and other explosives." It flowed naturally from my lips, as it was the stereotyped formula with which my discourses at the Educationische Instirut were usually commenced. My audience seemed, however, to be much amused, and the florid Celt was convulsed with admiration and merriment. Even the forbidding-looking man who had been referred to as the president condescended to smile his approval and remark that I adapted myself readily to my circumstances.
"These substances," I continued, "are powerful agents either for good or for evil. For good when used for the quarrying of rocks, the removal of impediments to navigation, or the destruction of houses during a conflagration. For evil—"
"I think you had better pass on to something more practical," said the president, grimly.
"On dipping starch into certain liquids," I resumed, "it is found to assume an explosive property. The attention of a learned countryman of ours, the chemist Schonbein, was directed to the fact, and he found that by treating cotton in a similar manner the effect was enormously increased. Schonbein was a man respected among his contemporaries, devoted to his country, and loyal— "
"Pass on!" said the president.
"After being treated in this fashion," I continued, "the cotton is found to gain eighty per cent. in weight. This substance is more susceptible to an increase of temperature than gunpowder, igniting at 300º Fahrenheit, while the latter requires a heat of 560º for its explosion. Guncotton can also be exploded by a blow, which is not the case with a mixture of carbon, sulphur, and saltpetre."
Here there were some angry murmurs among the company, and the president interrupted me for the third time.
"These gentlemen complain," he said, "that you have left no definite impression upon their minds as to how the substance is manufactured. Perhaps you will kindly dwell more fully upon the point."
"I have no further remarks to make," I said.
There was another threatening murmur, and the president took something out of the pocket of his coat, and toyed with it negligently. "I think you had better reconsider your decision," he remarked.
Most little men with spectacles are timid. Again I was no exception to the rule. I am ashamed to say that the peril of my Fatherland and even of my kaiser suddenly vanished from my recollection. I only realised that I, Otto von Spee, was standing upon the brink of eternity. After all, I argued, they could find out for themselves in any book upon chemistry. Why should my valuable life be sacrificed for such a trifle? I resumed my lecture with somewhat undignified haste.
"Guncotton is manufactured by steeping cotton waste in nitric acid. The explosion is caused by the oxygen of the acid combining with the carbon of the wool. It should be well cleaned with water after manufacture, otherwise the superfluous nitric acid acts directly upon the wool, charring it and gradually reducing it to a gummy mass. During this process heat is often evolved sufficient to explode the cotton, so that it is a dangerous matter to neglect the cleaning. After this a little sulphuric acid may be used to get rid of the moisture, when the substance is ready for use."
There was considerable applause at this point of my discourse, several of the audience taking notes of my remarks.
While I had been speaking I had been making a careful survey of the room in the hope of seeing some possibility of escape. The dais upon which I stood extended as far as the side wall, in which there was a window. The window was half open, and, could I reach it, there appeared to be a deserted looking garden outside, which might communicate with the street. No one could intercept me before I reached the window, but then there was the deadly weapon with which my cadaverous acquaintance was still trifling. He was sitting on the other side, and the table would partially protect me should I venture upon a dash. Could I screw up my courage to make an attempt? Not yet, at any rate.
"General von Link," I continued, "the Austrian artillerist, is one of our leading authorities upon guncotton. He experimented upon it in field-pieces, but—"
"Never mind that," said the president.
"After being manufactured, guncotton may be compressed under water. When compressed it is perfectly safe, and cannot be discharged. This sample which we have upon the table is not compressed. No amount of heat will have any effect upon the wet cotton. In an experiment tried in England a storehouse containing guncotton was burned down without there being any explosion. If, however, a charge of fulminated mercury, or a small piece of dry cotton, be fired in connection with a damp disc, it will be sufficient to discharge it. I shall now proceed to demonstrate this to you by an experiment."
An idea had come into my mind. Upon the table there was lying a mixture of sugar and chlorate of potash, used with sulphuric acid as a fuse for mining purposes. A bottle of the acid was also ready to my hand. I knew the white dense cloud of smoke which is raised by the imperfect combustion of these bodies. Could I make it serve as a screen between the weapon of the president and myself?
For a moment the plan seemed wild and unfeasible; still, it offered some chance of escape, and the more I thought it over the more reconciled I became to it. Of course, even after getting through the window there was the possibility that the garden might prove to be a cul-de-sac, and that my pursuers might overtake me. But then, on the other hand, I had no guarantee that I might not be murdered at the conclusion of my lecture. From what I knew of the habits of such men I considered it to be extremely probable. It was better to risk—but no, I would not think of what I was risking.
"I am now going to show you the effect of fulminate of mercury upon a small
