We move on tomorrow, so I'd better say something about Moving On. It seems to me in this one Dickens stretches the long arm of coincidence so far he almost pulls it out of its socket.
The policeman, stopping Jo on the street, finds a suspicious amount of money on him. Jo, needs someone to vouch for him. Guppy, happening to be passing by, says that Snagsby knows him well. Everyone goes to Snagsby's, where the Chadbands are taking tea. Jo tells his story of the mysterious woman in a veil, who wants to see Nemo's dwelling place, burial place, and Snagsby's house/office, and gives Jo a sovereign.
Thus the previously secret incident becomes known to a remarkable number of interested parties:
Snagsby, who used to give Nemo work.
Guppy, who is in love with Esther, maybe suspects something about Lady Dedlock, and is part of the law firm of Kenge and Carboy, also interested.
Mrs. Chadband, who had charge of Esther at one point.
I can swallow the others, since they're pretty local, but Mrs. Chadband is a bit much.
Still, it's setting us up for a number of possible plot complications.
