Cookiesmom, thanks for the kind words for "The Circle Squared." Sorry to cause a sleep shortage, since I often suffer the same affliction (and for the same reason), but I'm always glad to hear from a satisfied reader.
I'd like to recommend
A Shot In the Dark by Sheila Harper. It starts with a hard WHAM but resolves with lots of WAFF and toys put back in their proper places. It's intense and suspenseful.
