I am a German by birth and descent. My name is Schmidt. But by education I am quite as much an Englishman as a 'Deutscher', and by affection much more the former. My life has been spent pretty equally between the two countries, and I flatter myself I speak both languages without any foreign accent.
I count England my headquarters now: it is “home” to me. But a few years ago I was resident in Germany, only going over to London now and then on business. I will not mention the town where I lived. It is unnecessary to do so, and in the peculiar experience I am about to relate I think real names of people and places are just as well, or better avoided.
I was connected with a large and important firm of engineers. I had been bred up to the profession, and was credited with a certain amount of “talent”; and I was considered—and, with all modesty, I think I deserved the opinion—steady and reliable, so that I had already attained a fair position in the house, and was looked upon as a “rising man”. But I was still young, and not quite so wise as I thought myself. I came close once to making a great mess of a certain affair. It is this story which I am going to tell.
Our house went in largely for patents—rather too largely, some thought. But the head partner's son was a bit of a genius in his way, and his father was growing old, and let Herr Wilhelm - Moritz we will call the family name—do pretty much as he chose. And on the whole Herr Wilhelm did well. He was cautious, and he had the benefit of the still greater caution and larger experience of Herr Gerhardt, the second partner in the firm.
Patents and the laws which regulate them are strange things to have to do with. No one who has not had personal experience of the complications that arise could believe how far these spread and how involved they become. Great acuteness as well as caution is called for if you would guide your patent bark safely to port—and perhaps more than anything, a power of holding your tongue. I was no chatterbox, nor, when on a mission of importance, did I go about looking as if I were bursting with secrets, which is, in my opinion, almost as dangerous as revealing them. No one, to meet me on the journeys which it often fell to my lot to undertake, would have guessed that I had anything on my mind but an easy-going young fellow's natural interest in his surroundings, though many a time I have stayed awake through a whole night of railway travel if at all doubtful about my fellow-passengers, or not dared to go to sleep in a hotel without a ready-loaded gun by my pillow. For now and then - though not through me - our secrets did ooze out. And if, as has happened, they were secrets connected with Government orders or contracts, there was, or but for the exertion of the greatest energy and tact on the part of my superiors, there would have been, to put it plainly, the devil to pay.
