Behind the scenes
- In Robert Galbraith's first Cormoran Strike novel The Cuckoo's Calling, the victim's brother, who approaches Strike for his services, is mentioned to have a secretary called Alison Cresswell.
Cresswell means "stream where watercress grows," from the Old English caerse, "watercress," and well, "stream" or "spring." It is the name of several villages in England (as is the alternate spelling Creswell).
