“I did not observe that.”

“No, you wouldn’t. I spotted his artificial limb. But proceed.”

“I was struck by the snaky locks of grizzled hair which curled from under his old straw hat, and his face with its fierce, eager expression and the deeply lined features.”

“Very good, Watson. What did he say?”

“He began pouring out the story of his grievances. We walked down the drive together, and of course I took a good look round. I have never seen a worse-kept place. The garden was all running to seed, giving me an impression of wild neglect in which the plants had been allowed to find the way of Nature rather than of art. How any decent woman could have tolerated such a state of things, I don’t know. The house, too, was slatternly to the last degree, but the poor man seemed himself to be aware of it and to be trying to remedy it, for a great pot of green paint stood in the centre of the hall, and he was carrying a thick brush in his left hand. He had been working on the woodwork.

“He took me into his dingy sanctum, and we had a long chat. Of course, he was disappointed that you had not come yourself. ‘I hardly hardly expected,’ he said, ‘that so humble an individual as myself, especially after my heavy financial loss, could obtain the complete attention of so famous a man as Mr. Sherlock Holmes.’

“I assured him that the financial question did not arise. ‘No of course, it is art for art’s sake with him,’ said he, ‘but even on the artistic side of crime he might have found something here to study. And human nature, Dr. Watson — the black ingratitude of it all! When did I ever refuse one of her requests? Was ever a woman so pampered? And that young man — he might have been my own son. He had the run of my house. And yet see how they have treated me! Oh, Dr. Watson, it is a dreadful, dreadful world!’

“That was the burden of his song for an hour or more. He had, it seems, no suspicion of an intrigue. They lived alone save for a woman who comes in by the day and leaves every evening at six. On that particular evening old Amberley, wishing to give his wife a treat, had taken two upper circle seats at the Haymarket Theatre. At the last moment she had complained of a headache and had refused to go. He had gone alone. There seemed to be no doubt about the fact, for he produced the unused ticket which he had taken for his wife.”

“That is remarkable — most remarkable,” said Holmes, whose interest in the case seemed to be rising. “Pray continue, Watson. I find your narrative most arresting. Did you personally examine this ticket? You did not, perchance, take the number?”

“It so happens that I did,” I answered with some pride. “It chanced to be my old school number, thirty-one, and so is stuck in my head.”

“Excellent, Watson! His seat, then, was either thirty or thirty-two.”

“Quite so,” I answered with some mystification. “And on B row.”

But, when he turned round, he saw that the woman was gone.

She could not be far. Darting from the box, he set off at a run, regardless of the programme-sellers and check-takers.

On reaching the entrance-lobby, he saw her through an open door, crossing the pavement of the Chaussee d'Antin.

She was stepping into a motor-car when he came up with her.

The door closed behind her.

He seized the handle and tried to pull at it.

But a man jumped up inside and sent his fist flying into Lupin's face, with less skill but no less force than Lupin had sent his into Daubrecq's face.

Stunned though he was by the blow, he nevertheless had ample time to recognize the man, in a sudden, startled vision, and also to recognize, under his chauffeur's disguise, the man who was driving the car. It was the Growler and the Masher, the two men in charge of the boats on the Engbien night, two friends of Gilbert and Vaucheray: in short, two of Lupin's own accomplices.

When he reached his rooms in the Rue Chateaubriand, Lupin, after washing the blood from his face, sat for over an hour in a chair, as though overwhelmed. For the first time in his life he was experiencing the pain of treachery. For the first time his comrades in the fight were turning against their chief.

Mechanically, to divert his thoughts, he turned to his correspondence and tore the wrapper from an evening paper. Among the late news he found the following paragraphs:

"THE VILLA MAXIE-THERESE CASE"

"The real identity of Vaucheray, one of the alleged murderers of Leonard the valet, has at last been ascertained. He is a miscreant of the worst type, a hardened criminal who has already twice been sentenced for murder, in default, under another name.

"No doubt, the police will end by also discovering the real name of his accomplice, Gilbert. In any event, the examining-magistrate is determined to commit the prisoners for trial as soon as possible.

"The public will have no reason to complain of the delays of the law."

In between other newspapers and prospectuses lay a letter.

Lupin jumped when he saw it. It was addressed:

"Monsieur de Beaumont, Michel."

"Oh," he gasped, "a letter from Gilbert!"

It contained these few words:

"Help, governor!... I am frightened. I am frightened... "

Once again, Lupin spent a night alternating between sleeplessness and nightmares. Once again, he was tormented by atrocious and terrifying visions.

Poor boy!" murmured Lupin, when his eyes fell on Gilbert's letter next morning. "How he must feel it!"

On the very first day when he saw him, he had taken a liking to that well-set-up youngster, so careless, gay and fond of life. Gilbert was devoted to him, would have accepted death at a sign from his master. And Lupin also loved his frankness, his good humour, his simplicity, his bright, open face.

"Gilbert," he often used to say, "you are an honest man. Do you know, if I were you, I should chuck the business and become an honest man for good."

"After you, governor," Gilbert would reply, with a laugh.
