Used book – All the Colours of Darkness, Peter Robinson

A body is discovered, hanged in a wood near Eastvale. The man, quickly identified as Mark Hardcastle, was the popular and flamboyant set designer for the local theatre troupe's production of Othello. All signs point to suicide. But when his wealthy lover is found in a pool of blood, Detective Inspector Annie Cabbot has questions. Could a crime of passion have driven Mark to desperation and suicide? Plagued by doubt, she calls Alan Banks for backup, even if it means interrupting his holiday—and tearing him away from his new girlfriend... Their investigation plunges them into a murky and dangerous world for which the famous lines from Othello seem to have been written: "Jealousy, betrayal, envy, ambition, greed, lust, revenge... all the colours of darkness."
