Buried Treasures 6

The cover of my personal favourite of all of Jane Shaw's books: A Job for Susan (1969). This scene from Chapter 2, A Job for Bill, shows the girls discovering Sir Arthur Symes, a.k.a the Wicked Baronet, a.k.a. the Bad Bart, spying on Susan's house, more specifically the room she has baptized as Bluebeard's Chamber. The artist, whose signature appears in the bottom right-hand corner, is Roger Hall, who would go on to illustrate the British editions of the Three Investigators series.
