I thought one of the wonderful things about starting a series in the 1940s was that there would be so much time to move forward in.
And yet the second book, set only a few months after the first, is rooted more-or-less in the 1920s. A ghost becomes a sort of secondary client for the detective as his attempt to determine a house is not haunted does the reverse. His heart goes out to a murdered flapper and he seeks out a murderer on this very cold case in the hopes that getting justice will help her find peace. During the Prohibition Era, gangsters were often treated like celebrities and the elite might be found rubbing elbows with them. What kind of chaos happened when a teenager house-sat for his family at a manor too close to the Canadian border to be dry?
For Rafael, there's a bit of nostalgia in re-visiting the 20s. For me, there's a lot of research! And a little bit of irony.
