Under The Knife book description:
For attorney David Ransom, it begins as an open-and-shut case: malpractice.
Then Dr. Kate Chesne storms into his office, daring him to seek out the truth — that she’s being framed. When another patient turns up dead, David starts to believe her.
Somewhere in the Honolulu hospital, a killer walks freely. And now David finds himself asking the same questions Kate is desperate to have answered.
Who is next — and why?
