One thing that was forshadowed was the strike at the factory. Tension was building through the whole book between the factory owners and Mrs. Rattle, the leader of the suffragists, and it finally ended in a violent strike. I think this was obvious to both the reader and the characters. Another thing that was forshadowed is the marriage of Alfred Goodhand and Viola Riley. It was obvious to the readers that they loved each other, based on the way they acted together and talked to each other. I think it was a surprise to other characters, though.
