Frozen In Ice by Cynthia Eden

Is he a drop dead gorgeous…killer?
Delilah “Lila” Darrow doesn’t belong in the world of the rich and famous, but for one night, she’s going to wear the fanciest dress she can find and pretend that she does. Her plan—get close to reclusive billionaire Archer Radcliffe and find out…is he a murderer?

She knows exactly what Archer likes. She knows how to slip beneath his guard. She knows how to make him fall for her. With the right tools, Delilah believes she can finally make Archer pay for the crime he committed so long ago.

Payback is calling…and she’s wearing a dress made for sin.
Delilah is part of a group of crime solvers called the Ice Breakers—an online team made up of individuals who have the goal of solving cold cases. Five years ago, Delilah’s sister disappeared without a trace. Since then, Delilah has made it her mission to close as many unsolved cases as possible. Archer Radcliffe will be the latest target in her quest.
Except…Archer turns the tables on her. He sees through her lies. Tries to seduce her. And, he also swears his innocence.

Can she trust him? Or is he playing her?
Now that he has Delilah at his side, Archer can finally get the justice—the vengeance—he has craved. The only problem? The beautiful Delilah will be in danger. But Archer intends to stick close to her. So close that the world will believe they are completely in love. So close that a deadly enemy will want to strike. So close that just maybe—if he’s not careful—Archer might begin to fall for the woman he intends to use…
