Stick or twist - Diane Janes

"Janes deftly, suddenly transforms her audience's understanding of her protagonists several times without making delayed disclosures feel like literary trickery, keeping tension high to the very end"Publishers Weekly Starred Review

Wealthy heiress Jude Thackeray lost her trust in men following her terrible ordeal at the hands of a ruthless kidnapper. Now she's met Mark Medlicott, she is finally learning to love again.
But is Mark who - and what - he seems?

No one was ever arrested following the kidnap; there were no credible suspects even. Detective Sergeant Peter Betts and his colleague, DS Hannah McMahon, are determined to crack the case. However, the deeper they dig, the more anomalies they uncover, and it becomes increasingly clear there was more to the attempted kidnap than met the eye. Soon the pair find themselves in a desperate race against time in order to prevent a further catastrophe.
