This novel had such potential however, it falls completely flat at the end.

There are several stories occurring simultaneously in No One Can Know, with the JFK assassination being the primary story line, or at least I think it is. I'm not sure but since it's his face on the cover I imagine I am correct in my assumption.

The story is as follows: ex-CIA guy, Haines, in Dallas when JFK gets shot -- goes to work for his best buddy, Tucker, on his ranch where he meets best buddy's mistress, Carla -- Carla also good friends with Vincent who is Tucker's brother -- Carla is Vincent's daughter's,godmother who also happens to be at Tucker's ranch. Now throw in Tucker's wife and teenage daughter into the mix. Consequently none of the characters are developed to their full potential (although I really did like Ivy Jean).

There were some believable elements here and Ms. LaCava had a good concept in the conspiracy portion of her story. This all gets neutralized with an ending that comes off hurried and lacking in creativity.
