Last Thursday I began reading again in London--a condensation of "Copperfield," and "Mr. Bob Sawyer's Party," from "Pickwick," to finish merrily. The success of "Copperfield" is astounding. It made an impression that _I_ must not describe. I may only remark that I was half dead when I had done; and that although I had looked forward, all through the summer, when I was carefully getting it up, to its being a London sensation; and that although Macready, hearing it at Cheltenham, told me to be prepared for a great effect, it even went beyond my hopes. I read again next Thursday, and the rush for places is quite furious. Tell Townshend this with my love, if you see him before I have time to write to him; and tell him that I thought the people would never let me go away, they became so excited, and showed it so very warmly. I am trying to plan out a new book, but have not got beyond trying. Yours affectionately. [Sidenote: Mr. Walter Thornbury.] OFFICE OF "ALL THE YEAR ROUND," _Friday, April 18th, 1862._ MY DEAR THORNBURY, The Bow Street runners ceased out of the land soon after the introduction of the new police. I remember them very well as standing about the door of the office in Bow Street. They had no other uniform than a blue dress-coat, brass buttons (I am not even now sure that that was necessary), and a bright red cloth waistcoat. The waistcoat was indispensable, and the slang name for them was "redbreasts," in consequence. They kept company with thieves and the like, much more than the detective police do. I don't know what their pay was, but I have no doubt their principal complements were got under the rose. It was a very slack institution, and its head-quarters were The Brown Bear, in Bow Street, a public-house of more than doubtful reputation, opposite the police-office; and either the house which is now the theatrical costume maker's, or the next door to it. Field, who advertises the Secret Enquiry Office, was a Bow Street runner, and can tell you all about it; Goddard, who also advertises an enquiry office, was another of the fraternity. They are the only two I know of as yet existing in a "questionable shape." Faithfully yours always. [Sidenote: Mr. Baylis.] GAD'S HILL, ETC., _Wednesday, July 2nd, 1862._ MY DEAR MR. BAYLIS, I have been in France, and in London, and in other parts of Kent than this, and everywhere but here, for weeks and weeks. Pray excuse my not having (for this reason specially) answered your kind note sooner.
