A frozen corpse.
A missing witness.
Strange voices that aren't there.

One cold night, Lainie Goff, a glamorous young attorney on the fast track to a partnership at Portland's top firm, is found frozen in the trunk of her BMW on the local fishing pier.

Detectives Mike McCabe and Maggie Savage quickly uncover a long list of suspects: Lainie's boss, who was also her lover; an ex-priest who runs a shelter for runaway teens; an abusive stepfather who raped Lainie as a teen; and a creepy landlord who seems to know more than he should about her private life.

Still, there is no hard evidence until a mentally ill young woman who hears voices gives an island cop an eyewitness account he doesn't take seriously.

But when she too disappears, McCabe and Savage find themselves in a desperate race against time to stop a vicious killer before he rids himself of the only person who knows who he is.

The Tomorrow Heist is by Jack Soren. The blurb looks more like a thriller than a mystery, but this thread is for both.

Readers looking for twisting, fast-paced suspense will be swept away by Jack Soren’s newest tale of thrilling international adventure...

Jonathan Hall and Lew Katchbrow intended to leave life as international art thieves behind them—if only the money hadn’t run out. But when a shadowy organization approaches the duo offering compensation, protection, and prestige in exchange for their skills, Jonathan and Lew think it’s the answer to their problems…

But the nightmare has only just begun.

Suddenly Jonathan and Lew are thrust headlong into a race against time and a technology that science says shouldn’t exist. With the very nature of life and death on Earth hanging in the balance, it’s up to them to discover the truth behind Ashita—a terrifying futuristic city in the depths of the Pacific Ocean. But the clock is ticking. If Jonathan and Lew fail this heist, millions will die—and the human race will never be the same.
