PROFESSOR CHALLENGER was in the worst possible humour. As I stood at the door of his study, my hand upon the handle and my foot upon the mat, I heard a monologue which ran like this, the words booming and reverberating through the house:

'Yes, I say it is the second wrong call. The second in one morning. Do you imagine that a man of science is to be distracted from essential work by the constant interference of some idiot at the end of a wire? I will not have it. Send this instant for the manager. Oh! you are the manager. Well, why don't you manage? Yes, you certainly manage to distract me from work the importance of which your mind is incapable of understanding. I want the superintendent. He is away? So I should imagine. I will carry you to the law courts if this occurs again. Crowing cocks have been adjudicated upon. I myself have obtained a judgement. If crowing cocks, why not jangling bells? The case is clear. A written apology. Very good. I will consider it. Good morning.'

It was at this point that I ventured to make my entrance. It was certainly an unfortunate moment. I confronted him as he turned from the telephone – a lion in its wrath. His huge black beard was bristling, his great chest was heaving with indignation, and his arrogant grey eyes swept me up and down as the backwash of his anger fell upon me.

'Infernal, idle, overpaid rascals!' he boomed. 'I could hear them laughing while I was making my just complaint. There is a conspiracy to annoy me. And now, young Malone, you arrive to complete a disastrous morning. Are you here, may I ask, on your own account, or has your rag commissioned you to obtain an interview? As a friend you are privileged – as a journalist you are outside the pale.'

I was hunting in my pocket for McArdle's letter when suddenly some new grievance came to his memory. His great hairy hands fumbled about among the papers upon his desk and finally extracted a press cutting.

'You have been good enough to allude to me in one of your recent lucubrations,' he said, shaking the paper at me. 'It was in the course of your somewhat fatuous remarks concerning the recent Saurian remains discovered in the Solenhofen Slates. You began a paragraph with the words: «Professor G. E. Challenger, who is among our greatest living scientists-«'

'Well, sir?' I asked.

'Why these invidious qualifications and limitations? Perhaps you can mention who these other predominant scientific men may be to whom you impute equality, or possibly superiority to myself?'

'It was badly worded. I should certainly have said: «Our greatest living scientist,"' I admitted. It was after all my own honest belief. My words turned winter into summer.

'My dear young friend, do not imagine that I am exacting, but surrounded as I am by pugnacious and unreasonable colleagues, one is forced to take one's own part. Self-assertion is foreign to my nature, but I have to hold my ground against opposition. Come now! Sit here! What is the reason of your visit?'

I had to tread warily, for I knew how easy it was to set the lion roaring once again. I opened McArdle's letter. 'May I read you this, sir? It is from McArdle, my editor.'

'I remember the man – not an unfavourable specimen of his class.'

'He has, at least, a very high admiration for you. He has turned to you again and again when he needed the highest qualities in some investigation. That is the case now.'

'What does he desire?' Challenger plumed himself like some unwieldy bird under the influence of flattery. He sat down with his elbows upon the desk, his gorilla hands clasped together, his beard bristling forward, and his big grey eyes, half-covered by his drooping lids, fixed benignly upon me. He was huge in all that he did, and his benevolence was even more overpowering than his truculence.

'I'll read you his note to me. He says: «Please call upon our esteemed friend, Professor Challenger, and ask for his co-operation in the following circumstances. There is a Latvian gentleman named Theodore Nemor living at White Friars Mansions, Hampstead, who claims to have invented a machine of a most extraordinary character which is capable of disintegrating any object placed within its sphere of influence. Matter dissolves and returns to its molecular or atomic condition. By reversing the process it can be reassembled. The claim seems to be an extravagant one, and yet there is solid evidence that there is some basis for it and that the man has stumbled upon some remarkable discovery.

«I need not enlarge upon the revolutionary character of such an invention, nor of its extreme importance as a potential weapon of war. A force which could disintegrate a battleship, or turn a battalion, if it were only for a time, into a collection of atoms, would dominate the world. For social and for political reasons not an instant is to be lost in getting to the bottom of the affair. The man courts publicity as he is anxious to sell his invention, so that there is no difficulty in approaching him. The enclosed card will open his doors. What I desire is that you and Professor Challenger shall call upon him, inspect his invention, and write for the Gazette a considered report upon the value of the discovery. I expect to hear from you to-night.-

R. McARDLE.»

'There are my instructions, Professor,' I added, as I refolded the letter. 'I sincerely hope that you will come with me, for how can I, with my limited capacities, act alone in such a matter?'

'True, Malone! True!' purred the great man. 'Though you are by no means destitute of natural intelligence, I agree with you that you would be somewhat overweighted in such a matter as you lay before me. These unutterable people upon the telephone have already ruined my morning's work, so that a little more can hardly matter. I am engaged in answering that Italian buffoon, Mazotti, whose views upon the larval development of the tropical termites have excited my derision and contempt, but I can leave the complete exposure of the impostor until evening. Meanwhile, I am at your service.'

And thus it came about that on that October morning I found myself in the deep level tube with the Professor speeding to the North of London in what proved to be one of the most singular experiences of my remarkable life.

I had, before leaving Enmore Gardens, ascertained by the much-abused telephone that our man was at home, and had warned him of our coming. He lived in a comfortable flat in Hampstead, and he kept us waiting for quite half an hour in his ante-room whilst he carried on an animated conversation with a group of visitors, whose voices, as they finally bade farewell in the hall, showed that they were Russians. I caught a glimpse of them through the half-opened door, and had a passing impression of prosperous and intelligent men, with astrakhan collars to their coats, glistening top-hats, and every appearance of that bourgeois well-being which the successful Communist so readily assumes. The hall door closed behind them, and the next instant Theodore Nemor entered our apartment. I can see him now as he stood with the sunlight full upon him, rubbing his long, thin hands together and surveying us with his broad smile and his cunning yellow eyes.

He was a short, thick man, with some suggestion of deformity in his body, though it was difficult to say where that suggestion lay. One might say that he was a hunchback without the hump. His large, soft face was like an underdone dumpling, of the same colour and moist consistency, while the pimples and blotches which adorned it stood out the more aggressively against the pallid background. His eyes were those of a cat, and catlike was the thin, long, bristling moustache above his loose, wet, slobbering mouth. It was all low and repulsive until one came to the sandy eyebrows. From these upwards there was a splendid cranial arch such as I have seldom seen. Even Challenger's hat might have fitted that magnificent head. One might read Theodore Nemor as a vile, crawling conspirator below, but above he might take rank with the great thinkers and philosophers of the world.
