This is a The Cuckoo's Calling page.
Ciara Porter was a British supermodel and the best friend of Lula Landry. She was featured with Lula Landry in her last campaign shoot for the fashion designer Guy Somé, in which they both appeared 'naked except for handbags and wings.' Ciara was well known in London's party scene and was a friend of Evan Duffield, Lula's boyfriend. Duffield was staying at Ciara's flat the night Lula died.

Guy Somé referred to Ciara as 'a terrible slut.' 

Ciara had a one night stand with detective Cormoran Strike during his investigation into Lula Landry's death but (so far) has not been mentioned again.  

Ciara needed to figure out what happened to Lula, she had to.
