Don't Call The Night Judge. Nightlock Sins, #28

"The law is a house. Make sure everyone has a key."For every woman who was told the system would protect her. And for every woman who decided to protect herself. Estelle Ward is a brilliant paralegal investigator desperate to save her sister from a fraudulent eviction. Out of options, she dials a rumored midnight number and reaches Corvus Bell, the elusive "Night Judge." But Corvus isn't just a judge; he's a man who has been secretly building a massive RICO case against a corrupt judicial ring for fourteen months.
He's also a man who has been obsessively surveilling Estelle, preparing a hidden room in his chambers stocked with her favorite coffee, exact brand of shampoo, and specific pens. To protect her from a fabricated arrest warrant, Corvus places Estelle under a 72-hour judicial custody order, effectively locking her inside his courthouse. Estelle holds the one piece of original evidence Corvus needs to bring down the corruption ring, but handing it over means trusting a man who built a cage perfectly tailored to her every preference.
As they work side-by-side in the dark, pouring over case files and uncovering a 25-year conspiracy, the line between protector and captor blurs. He needs her evidence. She needs his jurisdiction. But in a locked building with a man whose dangerous obsession is masked as due process, the most terrifying thing Estelle can do is surrender.
