Before the Dawn
Only one person can help crack this case—but he’s also the prime suspect.
DC Sophie Jones was in the wrong place at the wrong time. Viciously bludgeoned one night in a dark alley, she is left fighting for her life in hospital, leaving no clues as to why she was there or what might have motivated the attack.
For Detective Karen Hart, fiercely protective of her young protégée, this is already deeply personal: an attack on Sophie is an attack on the whole team. When a car workshop near the crime scene is linked to local mobster Quentin Chapman, the man Hart has spent years trying to bring down, it’s hard not to jump to the most obvious conclusion.
But Chapman not only denies any knowledge of the incident—he asks for Karen’s help. Someone is killing his associates, and he fears he might be next. With little else to go on, Hart has no choice but to rely on her sworn enemy and his underworld connections for valuable information. Can she trust Chapman to tell her the truth—or will this shady collaboration be the last case of her career?

D. S. Butler
D. S. Butler doesn’t just write crime fiction—she deconstructs it with the precision of a scientist and the curiosity of someone who knows that the most dangerous secrets often hide in plain sight.
Before her novels ever found a home on bestseller lists, Butler (whose real name is Danica Britton) was elbow-deep in lab research. With a PhD in biochemistry and a career that once wove through hospital pathology labs and the University of Oxford, she was trained to ask questions, examine evidence, and look closer. Those same instincts now pulse through her thrillers—only the microscopes have been traded for murder scenes, and the puzzles involve motives instead of molecules.

Whether it's a missing person, a gruesome murder, or a long-forgotten cold case, Karen Hart brings a unique blend of grit and empathy to the investigation, pushing her to uncover truths even when they seem too dark to face.
