What Lupin felt most in the whole business was Daubrecq's revelation of the whereabouts of the flat. The police had entered his place in the Rue Chateaubriand. The identity of Lupin and Michel Beaumont had been recognized and certain papers discovered; and Lupin, while pursuing his aim, while, at the same time, managing various enterprises on which he had embarked, while avoiding the searches of the police, which were becoming more zealous and persistent than ever, had to set to work and reorganize his affairs throughout on a fresh basis.

His rage with Daubrecq, therefore, increased in proportion to the worry which the deputy caused him. He had but one longing, to pocket him, as he put it, to have him at his bidding by fair means or foul, to extract his secret from him. He dreamt of tortures fit to unloose the tongue of the most silent of men. The boot, the rack, red-hot pincers, nailed planks: no form of suffering, he thought, was more than the enemy deserved; and the end to be attained justified every means.

"Oh," he said to himself, "oh, for a decent bench of inquisitors and a couple of bold executioners!... What a time we should have!"

Every afternoon the Growler and the Masher watched the road which Daubrecq took between the Square Lamartine, the Chamber of Deputies and his club. Their instructions were to choose the most deserted street and the most favourable moment and, one evening, to to hustle him into a motor-car.

Lupin, on his side, got ready an old building, standing in the middle of a large garden, not far from Paris, which presented all the necessary conditions of safety and isolation and which he called the Monkey's Cage.

Unfortunately, Daubrecq must have suspected something, for every time, so to speak, he changed his route, or took the underground or a tram; and the cage remained unoccupied.

Lupin devised another plan. He sent to Marseilles for one of his associates, an elderly retired grocer called Brindebois, who happened to live in Daubrecq's electoral district and interested himself in politics. Old Brindebois wrote to Daubrecq from Marseilles, announcing his visit. Daubrecq gave this important constituent a hearty welcome, and a dinner was arranged for the following week.

The elector suggested a little restaurant on the left bank of the Seine, where the food, he said, was something wonderful. Daubrecq accepted.

This was what Lupin wanted. The proprietor of the restaurant was one of his friends. The attempt, which was to take place on the following Thursday, was this time bound to succeed.

Meanwhile, on the Monday of the same week, the trial of Gilbert and Vaucheray opened.

The reader will remember - and the case took place too recently for me to recapitulate its details - the really incomprehensible partiality which the presiding judge showed in his cross-examination of Gilbert. The thing was noticed and severely criticised at the time. Lupin recognized Daubrecq's hateful influence.

The attitude observed by the two prisoners differed greatiy. Vaucheray was gloomy, silent, hard-faced. He cynically, in curt, sneering, almost defiant phrases, admitted the crimes of which he had formerly been guilty. But, with an inconsistency which puzzled everybody except Lupin, he denied any participation in the murder of Leonard the valet and violently accused Gilbert. His object, in thus linking his fate with Gilbert's, was to force Lupin to take identical measures for the rescue of both his accomplices.

“This is Mrs. Merrilow, of South Brixton,” said my friend with a wave of the hand. “Mrs. Merrilow does not object to tobacco, Watson, if you wish to indulge your filthy habits. Mrs. Merrilow has an interesting story to tell which may well lead to further developments in which your presence may be useful.”

“Anything I can do —”

“You will understand, Mrs. Merrilow, that if I come to Mrs. Ronder I should prefer to have a witness. You will make her understand that before we arrive.”

“Lord bless you, Mr. Holmes,” said our visitor, “she is that anxious to see you that you might bring the whole parish at your heels!”

“Then we shall come early in the afternoon. Let us see that we have our facts correct before we start. If we go over them it will help Dr. Watson to understand the situation. You say that Mrs. Ronder has been your lodger for seven years and that you have only once seen her face.”

“And I wish to God I had not!” said Mrs. Merrilow.

“It was, I understand, terribly mutilated.”

“Well, Mr. Holmes, you would hardly say it was a face at all. That’s how it looked. Our milkman got a glimpse of her once peeping out of the upper window, and he dropped his tin and the milk all over the front garden. That is the kind of face it is. When I saw her — I happened on her unawares — she covered up quick, and then she said, ‘Now, Mrs. Merrilow, you know at last why it is that I never raise my veil.’ ”

“Do you know anything about her history?”

“Nothing at all.”

“Did she give references when she came?”

“No, sir, but she gave hard cash, and plenty of it. A quarter’s rent right down on the table in advance and no arguing about terms. In these times a poor woman like me can’t afford to turn down a chance like that.”

“Did she give any reason for choosing your house?”

“Mine stands well back from the road and is more private than most. Then, again, I only take the one, and I have no family of my own. I reckon she had tried others and found that mine suited her best. It’s privacy she is after, and she is ready to pay for it.”

“You say that she never showed her face from first to last save on the one accidental occasion. Well, it is a very remarkable story, most remarkable, and I don’t wonder that you want it examined.”

“I don’t, Mr. Holmes. I am quite satisfied so long as I get my rent. You could not have a quieter lodger, or one who gives less trouble.”

“Then what has brought matters to a head?”

“Her health, Mr. Holmes. She seems to be wasting away. And there’s something terrible on her mind. ‘Murder!’ she cries. ‘Murder!’ And once I heard her: ‘You cruel beast! You monster!’ she cried. It was in the night, and it fair rang through the house and sent the shivers through me. So I went to her in the morning. ‘Mrs. Ronder,’ I says, ‘if you have anything that is troubling your soul, there’s the clergy,’ I says, ‘and there‘s the police. Between them you should get some help.’ ‘For God’s sake, not the police!’ says she, ‘and the clergy can’t change what is past. And yet,’ she says, ‘it would ease my mind if someone knew the truth before I died.’ ‘Well,’ says I, ‘if you won’t have the regulars, there is this detective man what we read about’ — beggin’ your pardon, Mr. Holmes. And she, she fair jumped at it. ‘That’s the man,’ says she. ‘I wonder I never thought of it before. Bring him here, Mrs. Merrilow, and if he won’t come, tell him I am the wife of Ronder‘s wild beast show. Say that, and give him the name Abbas Parva. Here it is as she wrote it, Abbas Parva. ‘That will bring him if he’s the man I think he is.’ ”
