You had to rely on the power of love. That he loved you enough not to do the thing that would break your heart. It was paper-thin ice on which to stake your survival. Gretchen Falk has the perfect life - wealth, status, a loving family - and she'll do anything to keep it that way. So when her husband joins an expedition to Mount Kilimanjaro, she can't help but worry. What she doesn't expect is Frankie Callahan.
An ambitious artist desperate to outrun her past, Frankie sees the climb as a fresh start - until she meets Richard Falk: charismatic, rich and very married. Now, less than two weeks after their return to New York, Frankie's apartment is a blood-soaked crime scene, and Richard has been charged with her murder. There are just two things that Gretchen knows for sure: she's the only woman Richard has ever loved, and he would never hurt anyone.
Or would he?
