Silent Victim by Lynda La Plante

Vera Reynolds, a drag queen, performed "Falling in Love Again" while a sixteen-year-old "rent boy" lay dead in her fire-ravaged apartment. His murder echoed the violent realities of Soho's Vice Squad, but this case was different—an influential do-gooder was a prime suspect, threatening to expose the dark lives of powerful figures. Detective Jane Tennison, newly appointed head of the Vice Squad, faced a dilemma; she'd been instructed on whom to arrest and whom to protect. Nonetheless, she was determined to pursue justice, knowing a predator was still out there, even if it jeopardized her career.
