It occasionally happens servants are in league with thieves, and give them information as to the hour when to come, and the easiest way to break in. Sometimes servants basely admit the thieves into the premises to steal, and give them impressions of the keys, which enables them to make other keys to enter the house. Thieves sometimes take a blank key without wards, cover it with wax, work it in the keyhole against the wards of the lock, and by that means the impression is left in the wax. They then take it home and make a similar key. When looking into the lock they frequently strike a match on the doorway, and pretend to be lighting a pipe or cigar, which prevents passers by suspecting their object.

These are the general modes of housebreaking and burglary over the metropolis, but in order that we may have a more vivid and thorough conception of the subject, we shall give a more graphic detail of these felonies. We shall first advert to breaking into shops and warehouses, and then proceed to describe burglaries in various parts of the metropolis.

It frequently occurs that a thief enters a warehouse, or large shop, and secretes himself behind some goods, or in the cellar, or up the chimney. This could be done at any hour of the day, but is frequently managed when the servants or shopmen are out dining at mid-day, or towards evening, when the places of business are about to be closed. The thief may be respectably dressed, or not, according to the nature of the place of business. A person may call with some fictitious message, and keep one or more of the servants or shopmen in conversation while a confederate could meantime slip into the shop or warehouse, and if detected would seldom be suspected of being connected with this party. They sometimes hover for days in the neighbourhood of shops and warehouses they intend to plunder, and watch the most favourable opportunity to effect this object.

Towards evening when the servants are all gone, and the place of business closed, the rest of his companions come to the spot, consisting of one or more men, a woman being occasionally employed. While they are aware that one of their gang is secreted on the premises, as a precaution they sometimes knock at the door or ring the bell to ascertain if the servants or shopmen are gone. Should they be lingering in the premises, arranging the goods, engaged with their business-books, accounts, or otherwise, they ask for Mr. So-and-so, or have some other fictitious message.

On the departure of the people belonging to the shop, the thief inside generally opens the door to his companions on the given signal, when they proceed to rifle the premises of Manchester goods, cottons, silks, shawls, satins, or otherwise, and to store them into large bags they bring with them, which they place beside the door, when filled, to be conveniently carried away. They wrench open the desks, money-drawers, and other lockfasts with a jemmy, chisel, or screw-driver, as well as any doors which may be locked, occasionally using the cutter and saw, or other tools, and pierce through brick and other partition walls with an auger or other instrument. In many cases the doors of the apartments in warehouses are left open so that the thief has free access to the property.

Meantime a man or woman is watching outside while the thieves are busy plundering within, keeping a special look-out for the policeman proceeding on his beat. They have many ingenious expedients to decoy him away, by conversation or otherwise. The policeman is generally from fifteen to twenty minutes in going round his beat, so that they have ample time to carry off the booty.

While the thieves are busy collecting their spoil, the door is shut with a spring lock, or fastened with a padlock by means of a key they may have made for the purpose, so that the policeman has no suspicion of what is passing within. The former frequently remain for several hours on the premises, while a person outside is keeping watch, waiting to hear their signal when they have got the booty packed and ready. Should the coast be clear outside, notice is conveyed to the cart or cab, loitering somewhere in the vicinity, or which drives up at a certain hour, when the door opens. The plunder is quickly handed into the vehicle, which drives smartly away. The door is then shut, and the robbers walk off, possibly in a different direction to that in which the conveyance is gone.

Burglaries from jewellers’ shops are frequently effected by means of skeleton keys, or otherwise, by one or more men. A woman often carries the tools to the shop, and keeps watch. So soon as a favourable opportunity occurs they unlock the door and enter the premises, while a man or woman watches outside, the woman perhaps walking along the street as though she were a common prostitute, or familiarly accosting the policeman or other persons she meets, and decoying them away from the shop. In some cases, when she has not succeeded in getting the policeman away, she pretends to fall down in a fit, when he has possibly to take her to the nearest surgeon. Sometimes the woman feigns to be drunk, and is taken to the police station, which takes him off his beat. In the meanwhile the parties inside, with jemmy, chisel, saw, or other tools, and with silent lights and taper or dark lantern, break open the glass cases and boxes, and steal gold and silver watches, gold chains, brooches, pins, and other jewellery, which they deposit in a small carpet-bag, as well as rifle money from the desk.

Jewellers’ shops are sometimes entered by the thief getting into an unoccupied house next door, or two or three houses off, and proceeding along the roofs to the attic or roof of the house to be robbed, and going in by the attic window, or removing a few of the slates. The thieves then go downstairs and cut their way through the door or partition, and effect an entry into the shop.

Most of the robberies in jewellers’ shops have of late years been committed by means of false keys, or by cutting out a hole in the door or shutter with a cutter, which is done in a short space of time, and when the instrument is moistened it makes very little noise. This hole is covered with a piece of paper painted of the same colour as the door, and is pasted on, which prevents the police having any suspicion.
