I just started writing another novel. The working title is "Memorial Day Freight" (although "Freight Worse than Death" sounds enticing too) and it's the third in my Twin Cities Series. It's a story about embezzlement, kidnapping, murder, suicide, building construction and railroad freight. The action takes place in the lead up to Memorial Day and several of the plot strands culminate on the day itself.
I say I've started writing it but so far the bulk of my time has been taken up working out the plot and writing up a synopsis. Usually what happens to me is that I start writing and before long come to the conclusion, I don't know a damn thing about freight trains OR construction. Embezzlement is something I do know about. But lest you get the wrong idea, it's because I used to work in the finance industry and investigating frauds was part of my job. This was not quite as exciting as it sounds - well, actually sometimes it was (like the time I was sent to Milan, Italy to investigate potential embezzlement and there was suspected Mafia connections).
Anyway, my next job is to do some research into the stuff I intend to put in this novel that I currently have zero knowledge of. It's one of the most interesting parts of being a writer.
Another interesting part is getting paid royalties. But, then, I have to write the book first...
