It may not have been the most salubrious area of town in Nathaniel's time.
A report in the London Daily News of 3 October 1849 details the findings of a sanitary inspector on a recent visit.
"UPPER RATHBONE-PLACE: One side of this street is in St Pancras, and that parish cleanses and keeps in repair the upper part of the street, viz. from Charlotte-place to Percy-passage. I found it neglected and dirty, and the road out of repair. One of the inhabitants declared it had not been cleansed for more than a week. Between No 41 1/2 in this street and No 8, Percy-passage exist an offensive cess-pool and drain, which have not been cleaned for fourteen years, making these two houses very unhealthy."
A report in the previous year, 1848, named Peter Moore, a labourer, as residing at No. 8, Percy-passage when he gave evidence in a criminal trial.
