Taste of blood by Plante, Lynda La

Detective Jane Tennison made a bad choice. She was the one who put in a transfer to the quiet, local police station in Bromley, keen to escape the relentless pressure of her former West End department. Now she regrets her decision. The tedium of petty crime investigations even makes her question remaining in the force. But then a complicated domestic assault case lands on her desk – one that might still result in a murder charge if the victim dies of his injuries.
