A babysitter is murdered while watching a couple's young son. Once again there's a list of potential suspects. I won't go through the whole list, but can I just complain about a couple of the characters for a minute? Alright, the photographer woman who lives in the studio apartment all alone with no one else in the building. (1) Must she be a typical artist? I don't just mean the way she looks, I mean her attitude/personality. (2) How can she be so naive? She tells her assistant that someone has been coming in and out of her apartment when she's gone. She can tell because the chess pieces on the board have been moving. So what does she do? She declines her assistant's offer to stay over, you know, just in case a murderer or rapist is out to get her, which wouldn't be too surprising since one of her subjects was just murdered. She also acts as if it's not a big deal and in no way related to the murder. So...someone is breaking into your apartment,
