Okay folks, trying to be more forthright here.
what do you guys think of the use of flashbacks in a crime novel? in my novel a high priced model/prostitute is murdered. her murder is investigated. creeps crawling out of the woodwork. her sister wants to set everybody straight including the P. I. she's given up on the cops and the newspaper reporters. someone's feeding the P. I. with fantastic leads; (not the sister) she's never seen the stuff! letters, photos--and he's finding things aren't as black and white they seem. in a series of scaled down only pertinent flashbacks I want to bring out the dead woman's true self maybe before she started to fall--this then starts to turn the investigation on its head but eventually leads to a confrontation with the murderer--and so on!
