The problem is that she can't prove it. Even her razor-sharp powers of observation --- developed to an amazing capacity during the 20 years she spent blind and now in constant demand by law enforcement agencies --- have gotten her nowhere. But then a reporter who very publicly humiliated Kendra is murdered. Visiting the crime scene in search of anything that might link the brutal homicide to Colby, Kendra instead finds evidence that points to her.

As the body count rises, a gruesome pattern emerges. Someone is killing people in ways that mirror Kendra's most notorious cases…and he is not working alone.
