Ice Cold Heart P.J. Tracy

On a bitterly cold winter night, Kelly Ramage leaves her suburban home, telling her husband she's going to meet a friend.
But she never comes back.
When her body is discovered, murdered in what seems to be a sex game gone horribly wrong, Detectives Gino and Magozzi take the case, expecting to find a flirtatious trail leading straight to the killer.
However, Kelly's sinister lover has done a disturbingly good job of hiding his identity.
This isn't his first victim.
And she won't be the last . . .
