To each division of the Force is attached two officers, who are denominated “detectives.” The staff, or head-quarters, consists of six sergeants and two inspectors. Thus the Detective Police, of which we hear so much, consists of only forty-two individuals, whose duty it is to wear no uniform, and to perform the most difficult operations of their craft. They have not only to counteract the machinations of every sort of rascal whose only means of existence is avowed rascality, but to clear up family mysteries, the investigation of which demands the utmost delicacy and tact. One instance will show the difference between a regular and a detective policeman. Your wife discovers on retiring for the night, that her toilette has been plundered; her drawers are void; except the ornaments she now wears, her beauty is as unadorned as that of a quakeress: not a thing is left; all the fond tokens you gave her when her prenuptial lover, are gone; your own miniature, with its setting of gold and brilliants; her late mother’s diamonds; the bracelets “dear papa” presented on her last birth-day; the top of every bottle in the dressing-case brought from Paris by Uncle John, at the risk of his life, in February 1848, are off—but the glasses remain. Every valuable is swept away with the most discriminating villainy; for no other thing in the chamber has been touched; not a chair has been moved; the costly pendule on the chimney-piece still ticks; the entire apartment is as neat and trim as when it had received the last finishing sweep of the housemaid’s duster. The entire establishment runs frantically up stairs and down stairs; and finally congregates in my Lady’s Chamber. Nobody knows anything whatever about it; yet everybody offers a suggestion, although they have not an idea “who ever did it.” The housemaid bursts into tears; the cook declares she thinks she is going into hysterics; and at last you suggest sending for the Police; which is taken as a suspicion of, and insult on the whole assembled household, and they descend into the lower regions of the house in the sulks.
