The other thing that happens once I line out what has to take place in the book is that I am able to pinpoint what exactly I need to research. Note, I try to pinpoint my research to what I will specifically need for the book or else I could get lost in months of pure research, and that way lies total procrastination.
So my research list for this book looks something like this:
Antiquities Service in 1907 Cairo and Luxor
Means of traveling to Luxor
What household arrangements British archaeologists had in Luxor
Logistics of working on dig
Specifics of parents discovery
Luxor itself in 1907
Egyptian Nationalist movement in 1907
And then five or six elements that are far too spoilerish to mention here.
But the thing is, I know, KNOW, that as I research the list, new plot points and actions and events will become clear to me. That's why I love research--it is like the vein of ore from which I mine my stories and plots. There are always answers in research, and new intriguing questions, and things that are just so cool, I will simply have to include them.
And speaking of research, I stumbled on this site by the Art Institute of Chicago, which is a great resource for historical interiors. They have rooms from the 1500s up through the early 1800s.
