I've finished clue 3! Clue 4 well underway and shouldn't take long. Then I can start putting blocks together.
My mind is churning with ideas about the rest of the pieces. Anyone who wants to discuss it is welcome to PM me. Or, I was wondering, what would you think about starting an ancillary Bonnie Hunter mystery speculation thread for those who enjoy talking about it? That would eliminate the problem of people who want to avoid speculations stumbling over such posts. Just a thought.
