Mlle. Fouchette had accepted a home in the Rue St. Jacques and in this particular building because other people did not wish to live there, which made rooms cheap.

If you had cared to see what Mlle. Fouchette proudly called "home" you might have raised and let fall an old-fashioned iron knocker that sent a long reverberating roar down the tunnel-like entrance, to be lost in some hidden court beyond. Then a slide would slyly uncover a little brass "judas," disclosing a little, black, hard eye. Assuming that this eye was satisfied with you, the slide would be closed with a snap, bolts unshot, bars swung clear, and the heavy, iron-clamped door opened by a rascally-looking man whose blouse, chiefly, distinguished him from the race orang-outang.

Once within, you would notice that the door mentioned was ribbed with wrought iron and that two lateral bars of heavy metal were used to secure it from within. It dates from the Reign of Terror.

Having passed this formidable barrier, you would follow the tunnel to a square court paved with worn granite, enter a rear passage, and mount a narrow stone stairway, the steps of which are so worn as to leave an uncertain footing. If it happens to be in the night or early morning, the brass knobs in the centre of the doors will be ornamented with milk-bottles. There are four of these doors on every landing, and consequently four "appartements" on each floor; but as each wing seems to have been built in a different age from the others, and no two architects were able to accurately figure on reaching the same level, the effect is as uncertain as the stairs.

Mlle. Fouchette's "home" consisted of but a single square room fronting on the court by two windows with bogus balconies. The daylight from these windows showed a fireplace of immense size, and out of all proportion to the room, a bed smothered in the usual alcove by heavy curtains, a divan improvised from some ancient article of furniture, a small round table, and an easy-chair, and two or three others not so easy. There was one distinguished exception to the general effect of old age and hard usage, and this was a modern combination bureau, washstand, and dressing-table with folding mirror attachment, which when shut down was as demure and dignified as an upright piano.

The effective feature of a place the entire contents of which might have been extravagantly valued at twenty-five dollars was the exquisite harmony of colors. This effect is common to French interiors, where there is also a common tendency to over-decoration. The harmony began in the cheap paper on the walls, extended to bed and window draperies, and ended in the tissue-paper lamp-shade that at night lent a softened, rhythmical tone to the whole. This genial color effect was a delicate suggestion of blue, and the result was a doll-like daintiness that was altogether charming.

The autographic fan mania had left its mark over the divan in the shape of a gigantic fan constructed of little fans and opening out towards the ceiling. A few pen-and-ink and pencil sketches and studies, apparently the cast-off of many studios, were tacked up here and there. The high mantel bore an accumulation of odds and ends peculiar to young women of low means and cheap friendships. That was all. But a French girl can get the best results from a room, as she can from a hat, with the least money.

Mlle. Fouchette had reached all of this private magnificence through a singular concatenation of circumstances.

First, Inspector Loup.

That distinguished penologist had laid his hands upon Mlle. Fouchette in no uncertain way.
