very profound. I was invited to give them because I had been a friend and confidant of Kaufmann in Vienna. I was reporting some of the original ideas of a great man. There was little original of my own in them. And anywayâas you will knowâthat is really a branch of atomic physics.â
He had risen and gone to his desk, picked up a paper and read through it. â But I understand from this that you did some work on poison gases when you were in Vienna.â
âAh, yes, a little, when I was younger. But when I was twenty-six I gave all that up.â
âWhy?â
âBy then many of us in Austria could see the writing on the wall. As an Austrian, Hitler would never be content without possessing Austria. If he did take it I knew I would not want to stay. (Always, of course, I have been half English in sentiment.) But if my work there was such that it could contribute to military knowledge I knew I should not be allowed to leave. So I turned to other things.â
âVery far sighted of you.â He was still staring at the paper.
âYou see,â I said, âin spite of having avoided a liberal education I am really rather a jack of all trades. It is not really the way to achieve eminence.â
âSuppose,â he said, âyou were to see a gas manufactured in a laboratory, and demonstrated; would you be able to tell in what way it differed from a known gas, andâand recognise and remember the elements going to its composition?â
âOh, yes. If I had full access to the laboratory.â
He nodded, âPerhaps itâs time we stopped beating about the bush, Dr Mencken.â
I said I thought it was.
âYou have been very patient. But in a letter to your sisterâIâm so sorry but these things are always interceptedâin a letter to your sister written last Satuday you complain rather bitterly of this countryâs lack of confidence in your patriotism. I think we can prove to you now that we have a very real confidence in your patriotismâif youâll allow us to make use of it.â
âI hope I can.â
âWell ⦠itâs no sinecure that we offer.â
Outside, some machine was at work. I think it was a reaper, cutting and gathering the mixed corn that grew on the one-time lawn in front of the house.
âMy name is Brown,â he said. â I belong to the Special Branch of the British Intelligence Department. A little while ago we had a word from the head of our northers Italian organisation, appealing for extra help for a job which had come their way and asking if we could supply it. This we have been considering. The help they need is only one man. But unless that man conforms to certain definite requirements he would be better not sent.â
I sipped my whisky. Now I needed it. â I conform to these requirements?â
He smiled suddenly. â That, for the last two weeks, we have been trying to decide. The requirements are that he must be completely trustworthy, and able to keep his mouth shut if things go rightâor still more if they go wrong. He must speak Italian like a native and know German too. And he must be a first-class chemist. That is the great difficulty.â
âWith some knowledge on the subject of poison gases?â
âAs you say.â
âAnything else?â I asked with a touch of sarcasm.
âHe must be prepared to face all that such a mission would entail. Since we are at war, I imagine that goes without saying.â
I felt rather unwell. Half an hour ago I had been an interned alien with no immediate prospect of release and with only one prospect before me If I were released: a return to the seclusion of a laboratory. Now a sudden new world was open. I felt like a bird suddenly freed and too suddenly confronted with the menaces which were a part of freedomâthere was already a yearning for the protection of the cage.
Adventure and danger were well enough
