In 1935, Spurgeon wrote the pioneer study on the use of images in William Shakespeare's work, called "Shakespeare's Imagery, and what it tells us". It has been reprinted several times. In it she analyses the different types of images and motifs that he uses in his plays. She also shows that there is a "cluster", or there are several "clusters", of images in each of the major plays, for instance, illness and injury images in "Hamlet", and light and darkness images in "Romeo and Juliet".
