It was the apathy of La Rose Blanche quite as much as her inability to prove herself innocent that caused the increasing uneasiness in Benner’s mind. Not that he believed her for a moment guilty, but he knew that she was convicting herself with fatal rapidity. He, knowing her character, could understand how she could walk the streets all night in the storm. He, in the warmth of his passion for her, had often fought with the weather for the relief the struggle afforded him. Love-madness is nothing new, and the model’s actions were only one phase of it. At the little Café du Rat Mort, Benner now spent all his evenings, and on some days part of the afternoon. He grew to be one of the fixtures of the establishment. The habitués of the place had ceased to talk about him, and no longer pointed him out to the new-comers as the friend of the dead artist. The self-consciousness, which in the beginning was painful to him, gradually wore away, and he almost forgot himself at times in connection with the tragedy, and only kept constantly a dull sense of waiting—waiting for he knew not what. Evening after evening he sat at the little corner table of the front room of the café, smoking cigarettes, playing with the curious long-handled spoons, and occasionally sipping coffee or a glass of beer. The two tables between his seat and the window on the street changed occupants many times during the evening, and the newspapers grew sticky, fumbled, and worn at the hands of the frequent readers. The opposite side of this room of the café was filled by a long counter, covered on top with shining zinc, and divided into several compartments, on the highest of which stood the water carafes and a filter. Behind this counter sat Madame Lépic, the wife of the proprietor, placidly knitting from morning until midnight. When the street door opened she raised her eyes and greeted the comer with a hospitable smile; then her face resumed its normal expression of contentment. By carefully watching her it could be discovered that she had a habit of quickly glancing out from under her eyebrows and taking in the whole interior of the café in a flash of her dark little eye. Just beyond the end of the counter a partition, wainscoted as high as a man’s shoulder and with glass above, divided the café into two rooms. From where she sat Madame Lépic could overlook the four tables in the inner room as well as the three in the front. Her habit of constant watchfulness was cultivated, of course, by the necessity of keeping run of the two tired-looking waiters, who, like the rest of their class, had the weakness of being tempted by the abundance of money which passed through their hands. The police had already approached Madame Lépic, and she had given her testimony in regard to the actions of the model with the two young men. The police would not have been Parisian if they had not engaged madame to keep an eye on Benner. If he had not been too much occupied with his own thoughts, he might have detected her watching him constantly and persistently, even after he had ceased to be interesting in the eyes of the old habitués of the café.

It was a long four months after that terrible morning when Benner sat, late one afternoon, in the café brooding as usual. Before him on the stained marble slab stood a glass of water, a tall goblet and long spoon with twisted handle, and a porcelain match-holder half full of matches. Bent over the table, Benner was absent-mindedly arranging bits of matches on the slab, something in the shape of a guillotine. There were few people in the café. The click of the dominoes in the back room, an occasional word from one of the players, and the snap, snap, of Madame Lépic’s needles alone broke the quiet of the interior. As Benner sat watching the outline of the guillotine he had formed of broken matches, he saw one of the corner pieces straighten out, and thus destroy the symmetry of the arrangement. This was a piece which had been bent at right angles and only half broken off. Without paying particular attention to the occurrence, he took up the bit, threw it on the floor, and put another one, similarly broken, in its place. In a few moments this straightened out also, and this time the movement attracted Benner’s curiosity. Throwing it aside, he replaced it by a fresh piece, and this repeated the movement of the first two. Now his curiosity was excited in earnest, and his face and figure expressed such unusual interest that the sharp glitter was visible under Madame Lépic’s eyebrows, and her knitting went on only spasmodically. A fourth, fifth, and sixth piece was put in place on the corner of the little guillotine, and as the last one was moving in the same way as the first one did, Benner perceived that the water spilled on the table trickled down to where the broken match was placed. He took another match, as if to break it, but before the brittle wood snapped, his face lit up with a sudden expression of surprise and joy, and he started to his feet so violently as to nearly throw the marble slab from the iron legs. The click of the dominoes ceased, faces were seen at the glass of the partition, and Madame Lépic fairly stared, forgetting for once her rôle of disinterested knitter.

Without stopping to pay, without seeming to see anybody or anything, Benner strode nervously and quickly out of the café. When he was gone, Madame Lépic touched her bell, one of the drowsy waiters came, received a whispered order, and went out of the front door hatless. A few moments later, even before Benner had disappeared along the boulevard in the direction of his studio, a neatly dressed man came out of the police station near the café and walked in the same direction, the sculptor had taken. After Benner had entered the porte-cochère of the great building where his studio was, the police agent went into the concierge’s little office near the door, and sat there as if he were at home. In a few moments a nervous step was heard on the asphalt of the court-yard, and the agent had only time to withdraw into the gloom of the corner behind the stove when Benner passed out again, looking neither to the right nor the left. He was evidently much excited, and clutched rather than held a small parcel in his hand. The agent followed him a short distance behind, and, meeting a sergent de ville, paused to say a word to him. As Benner climbed on the top of an Odéon omnibus, the agent took a seat inside. Benner had not reached the interior boulevard before his studio was searched.

It was now nearly six o’clock, and the omnibus was crowded all the way across the city. As soon as the foot of the Rue des Beaux Arts was reached, Benner hurriedly descended, without waiting to stop the omnibus, and ran to the Academy. Here he sought the concierge, asked him a few questions, and then walked quickly away to the east side of the Luxembourg Gardens, where he rang the bell at the door of a house. He asked the servant who answered the bell if Professor Brunin was at home, and was evidently chagrined at being told he was absent and would not return for an hour or two. Entering the nearest café, he called for pen and paper, and wrote three pages rapidly, but legibly. By this time he had grown calmer in mind, not losing, however, the physical spring which his first excitement had induced. When his letter was finished he put it in an envelope, addressed it, and left it at the professor’s house. This done, he walked rapidly across the Luxembourg Gardens to the Odéon, took an omnibus, accompanied as before by the agent, and at the end of the route, in the Place Pigalle, he descended, hastened to his studio, and did not come out again that evening. The great window was lighted all night long, and the agent in the entry could hear sawing, hammering, and filing at intervals, as he listened at the door every hour or two.

The gray morning broke, and Benner was still at his work. As the daylight dimmed the light of the lamp, he seemed not to notice it, but continued bent over his table, where various blocks, pieces of sheet brass, and a few tools were scattered promiscuously about. A piece of brown paper lay on the floor with what appeared to be a glove. On the corner of the table was a rude imitation of a human hand made of wood, hinged so that the fingers would move. This was not of recent construction; but on a small drawing-board, over which Benner was leaning, was fixed a curious piece of mechanism which he was adjusting, having apparently just put it in working order. He had joined together five pieces of oak-wood, about three quarters of an inch wide and half an inch thick, arranged according to their length. The joints had been cut in the shape of quarter-circles, like the middle hinge of a carpenter’s rule. After these were fitted to each other, a sawcut was made in each one, and a piece of sheet brass inserted which joined the concave to the convex end. Two rivets on one end and one on the other, serving as a pivot, completed the hinge. The joints were so arranged that, when opened to the greatest extent, the five pieces composing the whole made a straight line. The longest piece of wood was fastened at the middle and outer end by screws, which held it firmly to the drawing-board. The shortest piece, on the opposite end of the line, had attached to it on the under side a pointed bit of brass like an index. As morning broke, Benner was engaged in fixing a bit of an ivory metre measure, which is marked to millimetres, underneath this index point. After this scale was securely fastened in its place the mechanism was evidently completed, for he straightened up, looked at his work from a distance, then bent over it again, and gently tried the joints, watching with some satisfaction the index as it moved along the scale. While preoccupied with this study, a sudden knock at the door caused him to start like a guilty man. He threw open the door almost tragically. It was only the concierge, who brought him a letter. He tore it open, and read it and re-read it with eagerness; then went to the table and carefully measured several times the whole length of the mechanism, from the inner screw of the longest piece to the end of the shortest. He then began to calculate and to cipher on the edge of the drawing-board. The letter read as follows:

“Monsieur,—En fait de renseignements sur la dilatation du bois je ne connais que ceux donnés par M. Reynaud dans son traité d’architecture, vol. i., pages 84 à 87 de la 2ᵉ êdition.

“Il en résulte que:

“1. Les bois verts se dilatent beaucoup plus que ceux purgés de sève.

“2. Que le chêne se dilate tantôt plus tantôt moins que le sapin, mais plus que le noyer.

“3. Que dans les conditions ordinaires, c’est à dire, avec les variations hygrométriques de l’air seulement, le coefficient de dilatation atteint au plus 0.018, d’où résulte qu’une planche de 0.20 deviendrait 0.2036.
