Read it through once

The flag had been struck, and the gun had been fired, at the right moment of time, and I felt as snugly cut off from the rest of Walworth as if the moat were thirty feet wide by as many deep. Nothing disturbed the tranquillity of the Castle, but the occasional tumbling open of John and Miss Skiffins: which little doors were a prey to some spasmodic infirmity that made me sympathetically uncomfortable until I got used to it. I inferred from the methodical nature of Miss Skiffins’s arrangements that she made tea there every Sunday night; and I rather suspected that a classic brooch she wore, representing the profile of an undesirable female with a very straight nose and a very new moon, was a piece of portable property that had been given her by Wemmick.
