Lily Pascale Series by Scarlett Thomas

Lily's interest in crime fiction not only lands her a job at a local college, but helps when she becomes mired in the deaths of two students.

Lily receives a troubling phone call from Jess, a freelance journalist. Jess wrote a feature on three women who were victims of stalking, and on the day it was published, all three women were found murdered. When Lily arrives in London to investigate, she finds out Jess is missing and has left behind a mysterious trail of clues.

Smart, willful, incautious and nearly terminally curious, Lily Pascale-university lecturer and part-time sleuth-faces her most baffling case in Seaside, when one-half of a pair of identical twins turns up dead.
