I spent more time on my blogs than the Glass Cliff this morning, and no, I didn't get up early! I had a quick look at chapter 6 for my critique partner: http://www.jenblackauthor.blogspot.com/ and then I went back to the Save the Cat structure and worked through that. I realised that because I want to keep the heroine wondering if it's voodoo or a nervous breakdown that's affecting her, then there must be a scene where she goes to a head doctor, right? And then I realised that the real reason I'm stuck is that as yet, I'm not sure what her exact job is, what the company she's been sent to boss does, and what scam the baddies don't want her to discover.
Research, then. I'll have a look on the Internet for really great swindle ideas tomorrow.
