“Not much fun for you, doing this for somebody who is nothing to you,” said Aaron.

“I shouldn’t if you were unsympathetic to me,” said Lilly. “As it is, it’s happened so, and so we’ll let be.”

“What time is it?”

“Nearly eight o’clock.”

“Oh, my Lord, the opera.”

And Aaron got half out of bed. But as he sat on the bedside he knew he could not safely get to his feet. He remained a picture of dejection.

“Perhaps we ought to let them know,” said Lilly.

But Aaron, blank with stupid misery, sat huddled there on the bedside without answering.

“Ill run round with a note,” said Lilly. “I suppose others have had flu, besides you. Lie down!”

But Aaron stupidly and dejectedly sat huddled on the side of the bed, wearing old flannel pyjamas of Lilly’s, rather small for him. He felt too sick to move.

“Lie down! Lie down!” said Lilly. “And keep still while I’m gone. I shan’t be more than ten minutes.”

“I don’t care if I die,” said Aaron.

Lilly laughed.

“You’re a long way from dying,” said he, “or you wouldn’t say it.”

But Aaron only looked up at him with queer, far–off, haggard eyes, something like a criminal who is just being executed.

“Lie down!” said said Lilly, pushing him gently into the bed. “You won’t improve yourself sitting there, anyhow.”

Aaron lay down, turned away, and was quite still. Lilly quietly left the room on his errand.

The doctor did not come until ten o’clock: and worn out with work when he did come.

“Isn’t there a lift in this establishment?” he said, as he groped his way up the stone stairs. Lilly had heard him, and run down to meet him.

The doctor poked the thermometer under Aaron’s tongue and felt the pulse. Then he asked a few questions: listened to the heart and breathing.

“Yes, it’s the flu,” he said curtly. “Nothing to do but to keep warm in bed and not move, and take plenty of milk and liquid nourishment. I’ll come round in the morning and give you an injection. Lungs are all right so far.”

“How long shall I have to be in bed?” said Aaron.

“Oh—depends. A week at least.”

Aaron watched him sullenly—and hated him. Lilly laughed to himself. The sick man was like a dog that is ill but which growls from a deep corner, and will bite if you put your hand in. He was in a state of black depression.

Lilly settled him down for the night, and himself went to bed. Aaron squirmed with heavy, pained limbs, the night through, and slept and had bad dreams. Lilly got up to give him drinks. The din in the market was terrific before dawn, and Aaron suffered bitterly.

In the morning he was worse. The doctor gave him injections against pneumonia.

“You wouldn’t like me to wire to your wife?” said Lilly.

“‘Then we can hardly get there before midnight. I suppose there would be no chance of a train back. I should be compelled to stop the night.’

“‘Yes, we could easily give you a shake-down.’

“‘That is very awkward. Could I not come at some more convenient hour?’

“‘We have judged it best that you should come late. It is to recompense you for any inconvenience that we are paying to you, a young and unknown man, a fee which would buy an opinion from the very heads of your profession. Still, of course, if you would like to draw out of the business, there is plenty of time to do so.’

“I thought of the fifty guineas, and of how very useful they would be to me. ‘Not at all,’ said I, ‘I shall be very happy to accommodate myself to your wishes. I should like, however, to understand a little more clearly what it is that you wish me to do.’

“‘Quite so. It is very natural that the pledge of secrecy which we have exacted from you should have aroused your curiosity. I have no wish to commit you to anything without your having it all laid before you. I suppose that we are absolutely safe from eavesdroppers?’

“‘Entirely.’

“‘Then the matter stands thus. You are probably aware that fuller’s-earth is a valuable product, and that it is only found in one or two places in England?’

“‘I have heard so.’

“‘Some little time ago I bought a small place — a very small place — within ten miles of Reading. I was fortunate enough to discover that there was a deposit of fuller’s-earth in one of my fields. On examining it, however, I found that this deposit was a comparatively small one, and that it formed a link between two very much larger ones upon the right and left — both of them, however, in the grounds of my neighbours. These good people were absolutely ignorant that their land contained that which was quite as valuable as a gold-mine. Naturally, it was to my interest to buy their land before they discovered its true value, but unfortunately I had no capital by which I could do this. I took a few of my friends into the secret, however, and they suggested that we should quietly and secretly work our own little deposit and that in this way we should earn the money which would enable us to buy the neighbouring fields. This we have now been doing for some time, and in order to help us in our operations we erected a hydraulic press. This press, as I have already explained, has got out of order, and we wish your advice upon the subject. We guard our secret very jealously, however, and if it once became known that we had hydraulic engineers coming to our little house, it would soon rouse inquiry, and then, if the facts came out, it would be good-bye to any chance of getting these fields and carrying out our plans. That is why I have made you promise me that you will not tell a human being that you are going to Eyford to-night. I hope that I make it all plain?’
