TANA FRENCH - The Secret Place

The photo shows a boy who was murdered a year ago.

The caption says, 'I KNOW WHO KILLED HIM'.

Detective Stephen Moran hasn't seen Holly Mackey since she was a nine-year-old witness to the events of Faithful Place. Now she's sixteen and she's shown up outside his squad room, with a photograph and a story.

Even in her exclusive boarding school, terrible things can happen. The previous year, a boy from the neighbouring school, was found murdered on the grounds. And today, in the Secret Place - the school noticeboard where girls can pin up their secrets anonymously - Holly found the card.

Solving this case could take Stephen onto the Murder squad. But to get it solved, he will have to work with prickly Detective Antoinette Conway. And he will have to find a way into the strange, charged, mysterious world that Holly inhabits, disentangling a twisted web of lies in the process.
