Here we had a very extraordinary interruption.

Holmes raised his hand for silence. Then he strode across the room, flung open the door, and dragged in a great gaunt woman whom he had seized by the shoulder. She entered with ungainly struggle like some huge awkward chicken, torn, squawking, out of its coop.

“Leave me alone! What are you a-doin’ of?” she screeched.

“Why, Susan, what is this?”

“Well, ma’am, I was comin’ in to ask if the visitors was stayin’ for lunch when this man jumped out at me.”

“I have been listening to her for the last five minutes, but did not wish to interrupt your most interesting narrative. Just a little wheezy, Susan, are you not? You breathe too heavily for that kind of work.”

Susan turned a sulky but amazed face upon her captor. “Who be you, anyhow, and what right have you a-pullin’ me about like this?”

“It was merely that I wished to ask a question in your presence. Did you, Mrs. Maberley, mention to anyone that you were going to write to me and consult me?”

“No, Mr. Holmes, I did not.”

“Who posted your letter?”

“Susan did.”

“Exactly. Now, Susan, to whom was it that you wrote or sent a message to say that your mistress was was asking advice from me?”

“It’s a lie. I sent no message.”

“Now, Susan, wheezy people may not live long, you know. It’s a wicked thing to tell fibs. Whom did you tell?”

“Susan!” cried her mistress, “I believe you are a bad, treacherous woman. I remember now that I saw you speaking to someone over the hedge.”

“That was my own business,” said the woman sullenly.

“Suppose I tell you that it was Barney Stockdale to whom you spoke?” said Holmes.

“Well, if you know, what do you want to ask for?”

“I was not sure, but I know now. Well now, Susan, it will be worth ten pounds to you if you will tell me who is at the back of Barney.”

“Someone that could lay down a thousand pounds for every ten you have in the world.”

“So, a rich man? No; you smiled — a rich woman. Now we have got so far, you may as well give the name and earn the tenner.”

“I’ll see you in hell first.”

“Oh, Susan! Language!”

“I am clearing out of here. I’ve had enough of you all. I‘ll send for my box to-morrow.” She flounced for the door.

“Good-bye, Susan. Paregoric is the stuff.... Now,” he continued, turning suddenly from lively to severe when the door had closed behind the flushed and angry woman, “this gang means business. Look how close they play the game. Your letter to me had the 10 P.M. postmark. And yet Susan passes the word to Barney. Barney has time to go to his employer and get instructions; he or she — I incline to the latter from Susan’s grin when she thought I had blundered — forms a plan. Black Steve is called in, and I am warned off by eleven o’clock next morning. That‘s quick work, you know.”

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.
