How is the Law Office depicted and what does it reveal about Mr.Jaggers ?Great Expectations by Charles Dickens

The rather unscrupulous Mr. Jaggers, based upon a real
lawyer with whomDickens was familiar, keeps an office in Little Britain by Newgate
Prison.  It is on a markedly gloomy street that this prison is located.  Mr. Jaggers's
office is lighted only by a patched skylight and is in shadow; Pip describes it as "a
most dismal place." There are not the pile of papers that Pip has expected, but instead
odd objects such as an old rusty pistol, a sword in its scabbard, several odd-looking
boxes, and two frightful death masks on a shelf.

Mr.
Jaggers's black chair is covered in horsehair with the tacks around it like the nails on
a coffin; It is also not cleanly. The small room has a line from the greasy heads that
seemto fill the room until Pip tells Wemmick that he will stroll around while waiting. 
As he does so, Pip hears rather sordid-looking people speak of Jaggers.  From their
appearance and the appearance of Mr. Jaggers's office, Pip deduces that Mr. Jaggers
himself is but a few steps on the other side of crime himself.  He deals with the lowest
form of criminals and shows no sympathy for them in doing so.  As a reminder of the
cruelty of the environment in which he practices, Jaggers keeps the death masks of two
men for whom he could not win their cases.
