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 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 hustle him into a motor-car.

Lupin, on his side, got 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 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 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.

My companion was paralyzed by the sudden horror of it, but I, as may well be imagined, had every sense on the alert. And I had need, for it was speedily evident that we were in the presence of an extraordinary case. The man was dressed only in his Burberry overcoat, his trousers, and an unlaced pair of canvas shoes. As he fell over, his Burberry, which had had been simply thrown round his shoulders, slipped off, exposing his trunk. We stared at it in amazement. His back was covered with dark red lines as though he had been terribly flogged by a thin wire scourge. The instrument with which this punishment had been inflicted was clearly flexible, for the long, angry weals curved round his shoulders and ribs. There was blood dripping down his chin, for he had bitten through his lower lip in the paroxysm of his agony. His drawn and distorted face told how terrible that agony had been.

I was kneeling and Stackhurst standing by the body when a shadow fell across us, and we found that Ian Murdoch was by our side. Murdoch was the mathematical coach at the establishment, a tall, dark, dark thin man, so taciturn and aloof that none can be said to have been his friend. He seemed to live in some high abstract region of surds and conic sections, with little to connect him with ordinary life. He was looked upon as an oddity by the students, and would have been their butt, but there was some strange outlandish blood in the man, which showed itself not only in his coal-black eyes and swarthy face but also in occasional outbreaks of temper, which could only be described as ferocious. On one occasion, being plagued by a little dog belonging to McPherson, he had caught the creature up and hurled it through the plate-glass window, an action for which Stackhurst would certainly have given him his dismissal had he not been a very valuable teacher. Such was the strange complex man who now appeared beside us. He seemed to be honestly shocked at the sight before him, though the incident of the dog may show that there was no great sympathy between the dead man and himself.

“Poor fellow! Poor fellow! What can I do? How can I help?”

“Were you with him? Can you tell us what has happened?”

“No, no, I was late this morning. I was not on the beach at all. I have come straight from The Gables. What can I do?”

“You can hurry to the police-station at Fulworth. Report the matter at once.”

Without a word he made off at top speed, and I proceeded to take the matter in hand, while Stackhurst, dazed at this tragedy, remained by the body. My first task naturally was to note who was on the beach. From the top of the path I could see the whole sweep of it, and it was absolutely deserted save that two or three dark figures could be seen far away moving towards the village of Fulworth. Having satisfied myself upon this point, I walked slowly down the path. There was clay or soft marl mixed with the chalk, and every here and there I saw the same footstep, both ascending and descending. No one else had gone down to the beach by this track that morning. At one place I observed the print of an open hand with the fingers towards the incline. This could only mean that poor McPherson had fallen as he ascended. There were rounded depressions, too, which suggested that he had come down upon his knees more than once. At the bottom of the path was the considerable lagoon left by the retreating tide. At the side of it McPherson had undressed, for there lay his towel on a rock. It was folded and dry, so that it would seem that, after all, he had never entered the water. Once or twice as I hunted round amid the hard shingle I came on little patches of sand where the print of his canvas shoe, and also of his naked foot, could be seen. The latter fact proved that he had made all ready to bathe, though the towel indicated that he had not actually done so.
