This is the first in a fun series for kids (ages 8 - 11 I'd say) set in Victorian London. Rose Raventhorpe is the daughter of a society mother and an adventurer father. Needless to say, Rose takes after her father but is forced to fill the role of a moneyed female of the time. Happily her mother is so often engaged in her various activities that Rose can follow her own interests, and when butlers are getting murdered and the famous cat statues are disappearing, Rose is determined to find out who the culprit is.

Fun.
