Good mystery where main character lost memory and has to back track

I'm looking for a good recommendation where the main character lost memory and either has a crime they have to back track and figure out or just needs to retrace to figure out who they are. "Before I Go To Sleep" is the only book I can think of similar to this. The movie Unknown with Liam Neeson is a good one that's similar to what I'm looking for. Thanks all om advance.
