Wicked Secret by Valerie Keogh really contains a wicked secret. There is the main murder mystery. Who did it? That is not the wicked secret. There is a secondary and much more entertaining secondary murder mystery. Who did it? That is not the wicked secret either. The perpetrators of the two murders hoped their identities were secret, but those identities were not wicked secrets. Nicola, an abrasive almost psychic, a person who had helped the police solve gruesome crimes in the past, had a really wicked secret. My challenge will be to present an idea of what the book is about without revealing the secret. It is an interesting secret and should support reader interest in this novel as well as follow up novels.
