I generally shy away from interrogations.
Rarely do I sit a character down and put the screws to him or her before letting them into my story. Physical specs and a sentence or two of background are jotted down, of course, but nothing more. I like to flesh the players out in-story, be as surprised as the reader at the blokes’ histories.
A Cozy Mystery is a different beast, however.
So, the interrogations will begin today. My OCD is already drooling. Heaven help us all.
