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

Aaron anyhow 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.

“And what did you learn from him?”

“Nothing.”

“Could he throw no light?”

“None at all. I was inclined to think at one time that he knew who had done it and was screening him or her, but I am convinced now that he is as puzzled as everyone else. He is not a very quick-witted youth, though comely to look at and, I should think, sound at heart.”

“I cannot admire his taste,” I remarked, “if it is indeed a fact that he was averse to a marriage with so charming a young lady as this Miss Turner.”

“Ah, thereby hangs a rather painful tale. This fellow is madly, insanely, in love with her, but some two years ago, when he was only a lad, and before he really knew her, for she had been away five years at a boarding-school, what does the idiot do but get into the clutches of a barmaid in Bristol and marry her at a registry office? No one knows a word of the matter, but you can imagine how maddening it must be to him to be upbraided for not doing what he would give his very eyes to do, but what he knows to be absolutely impossible. It was sheer frenzy of this sort which made him throw his hands up into the air when his father, at their last interview, was goading him on to propose to Miss Turner. On the other hand, he had no means of supporting himself, and his father, who was by all accounts a very hard man, would have thrown him over utterly had he known the truth. It was with his barmaid wife that he had spent the last three days in Bristol, and his father did not know where he was. Mark that point. It is of importance. Good has come out of evil, however, for the barmaid, finding from the papers that he is in serious trouble and likely to be hanged, has thrown him over utterly and has written to him to say that she has a husband already in the Bermuda Dockyard, so that there is really no tie between them. I think that that bit of news has consoled young McCarthy for all that he has suffered.”

“But if he is innocent, who has done it?”

“Ah! who? I would call your attention very particularly to two points. One is that the murdered man had an appointment with someone at the pool, and that the someone could not have been his son, for his son was away, and he did not know when he would return. The second is that the murdered man was heard to cry ‘Cooee!’ before he knew that his son had returned. Those are the crucial points upon which the case depends. And now let us talk about George Meredith, if you please, and we shall leave all minor matters until to-morrow.”

There was no rain, as Holmes had foretold, and the morning broke bright and cloudless. At nine o’clock Lestrade called for us with the carriage, and we set off for Hatherley Farm and the Boscombe Pool.

“There is serious news this morning,” Lestrade observed. “It is said that Mr. Turner, of the Hall, is so ill that his life is despaired of.”

“An elderly man, I presume?” said Holmes.

“About sixty; but his constitution has been shattered by his life abroad, and he has been in failing health for some time. This business has had a very bad effect upon him. He was an old friend of McCarthy’s, and, I may add, a great benefactor to him, for I have learned that he gave him Hatherley Farm rent free.”
