Enjoyed Carol Higgins Clark's "Cursed". It's a fast-paced, good story as i've come to expect of Clark.
OTOH, if you are at the library, as i was last week, and think "i haven't read a Susan Issac book in a long time" and pick out Past Perfect and think to take it home, DONT! It was ghastly long, with unneccesary extensions of scenes that go on and on w/out adding to the story; a protagonist that, IMO, does really idiotic things for a supposedly intelligent woman who worked for the CIA and is the developer and writer of a cable television spy show. I.e., leaving her pocketbook, phone and keys in an unlocked car to go breaking into a person's house she has just concluded was nuts and knew she (the nut) was on her way home, about to pull into the driveway next to the protagonist's car, which would be a clue that the protagonist must be somewhere on, or in, her property.
I know mysteries/spy novels, etc need to have some unrealistic fantasy, but geez....it just wasn't working for me. Actually .......now that i think about it, the protagonist was written as being both smart and dipsy, in a silly-woman kind if way, maybe that turned me off w/out my realizing it til now.
