The second book of the Red Rope series was terrifically difficult to write. There was a simpler alternative which would have been easier to write, but that – I felt – would be cheating. I wanted to do due diligence to a much more complicated dynamic, and to be honest, when I started it I wasn’t sure I was going to be able to make sense of it.

The Death at the Mansion series provided some useful and prescient insights that I hadn’t encountered before. Audio recordings of Jonah Shacknai’s police statement helped in the process of unraveling certain psychological mechanisms underlying this case.

Do we know all there is to know about this case? No, but we’re getting there.
