A bit of romance is thrown into the seemingly transparent plot, involving a Romeo and Juliet scenario between Connie and Taylor Hall, the drug addict her father forbids her to associate with. It's not very significant to the story, but it does connect with the twist at the end, when the killer is revealed--though the twist isn't very surprising. Still, "Pat-A-Cake, Pat-A-Cake" is a pretty good addition to the Nursery Crimes series, which includes two others: "Jack and Jill" and "There Was An Old Woman"--both worth checking out if you liked this one.
