Two more yellowbacks ...

 Well, Walter Besant seems to have been pretty popular with the good folk of Stanley in the late nineteenth century, with today's guerrilla cataloguing uncovering another two yellowback editions of his books -

By Celia's Arbour and The Monks of Thelema, both written in collaboration with James Rice.

Both novels were originally published as Victorian triple-deckers, but these Chatto and Windus yellowbacks contain the whole novel as a single volume.

As can be seen, time has not been kind to the books and they are in a pretty fragile condition, perhaps a reflection of their popularity at the time...
