Books three and four will involve mental health in the early teens (think Will being committed to an asylum to try to find a killer) and women's suffrage, respectively. There were a lot of nasty things going on in asylums at this time, so I've got a lot of fodder for Will's trials and tribulations in that book. For the other, I've got politics and death threats to work with. The Michigan ballot for the 1912 presidential election contained a constitutional amendment to legalize the vote for women. The campaign was filled with dirty tricks and behind the scenes machinations, and ended with a recount, "lost" ballots, and a stolen election.
Both nice backdrops for mysteries, I think!
Motor City Shakedown is launching this September, book three will be published in fall 2012 and book four in fall 2013.
Okay, time to write some books!
