Wichwood Gallery

Dulwich Picture Gallery is featured as Wichwood Gallery in the plot of Susan Rushes In, when Susan, Midge and Pea-green foil a robbery there, although Peregrine gets all the credit in the local newspaper. The Gallery is described in Chapter 13:

Opposite the Carmichaels' house there was a small but quite famous picture gallery. The Carmichaels - naturally, seeing that they lived opposite - had scarecely ever been in it, but as children their nanny had often taken them into the very pretty garden which surrounded it.
