Transformation

If you grind castor sugar with an equal quantity of chlorate of potash, the result is an innocent-looking white compound, sweet to the taste, and sometimes beneficial in the case of a sore throat. But if you dip a glass rod into a small quantity of sulphuric acid, and merely touch the harmless-appearing mixture with the wet end of the rod, the dish which contains it becomes instantly a roaring furnace of fire, vomiting forth a fountain of burning balls, and filling the room with a dense, black, suffocating cloud of smoke.

So strange a combination is that mystery which we term Human Nature, that a touch of adverse circumstance may transform a quiet, peaceable, law-abiding citizen into a malefactor whose heart is filled with a desire for vengeance, stopping at nothing to accomplish it.

In a little narrow street off the broad Rue de Rennes, near the great terminus of Mont-Parnasse, stood the clock-making shop of the brothers Delore. The window was filled with cheap clocks, and depending from a steel spring attached to the top of the door was a bell, which rang when any one entered, for the brothers were working clockmakers, continually busy in the room at the back of the shop, and trade in the neighbourhood was not brisk enough to allow them to keep an assistant. The brothers had worked amicably in this small room for twenty years, and were reported by the denizens of that quarter of Paris to be enormously rich. They were certainly contented enough, and had plenty of money for their frugal wants, as well as for their occasional exceedingly mild dissipations at the neighbouring cafe. They had always a little money for the church, and a little money for charity, and no one had ever heard either of them speak a harsh word to any living soul, and least of all to each other. When the sensitively adjusted bell at the door announced the arrival of a possible customer, Adolph left his work and attended to the shop, while Alphonse continued his task without interruption. The former was supposed to be the better business man of the two, while the latter was admittedly the better workman. They had a room over the shop, and a small kitchen over the workroom at the back; but only one occupied the bedroom above, the other sleeping in the shop, as it was supposed that the wares there displayed must have formed an almost irresistible temptation to any thief desirous of accumulating a quantity of time-pieces. The brothers took week-about at guarding the treasures below, but in all the twenty years no thief had yet disturbed their slumbers.

One evening, just as they were about to close the shop and adjourn together to the cafe, the bell rang, and Adolph went forward to learn what was wanted. He found waiting for him an unkempt individual of appearance so disreputable, that he at once made up his mind that here at last was the thief for whom they had waited so long in vain. The man's wild, roving eye, that seemed to search out every
