After a very long time, a male lead forced me to sympathise with him. Poor guy was simply trying to do his job. Falling in love with a suspect while you're in an under-cover job was bound to be a miserable mess. I suppose the heroine's allowed to feel indignation at having been considered a suspected serial killer, but give the poor guy a break. He couldn't have disclosed any information to her. Until she was categorically absolved of any kind of suspicion, he couldn't have done much to help her. Really a comically sad set of events. 
 I liked the breezy writing. I also adored how the characters were fleshed out. They had no unnecessary emotional hang-ups and thank God they weren't egoistic, proud fools. 
 Similar book- You don't know about Jack. (another wonderful chick lit.)
