This time I stopped in the outer reception room of my office and spoke to Effie.
"Effie." I said very quietly so as not to be overheard in my inner office, "There is something very strange going on here. Will YOU please step out into the street and see if there is anyone or anything you would say is unusual out there? I am going to stay right here to be sure our guest doesn't take it on the lam."
"Of course, Constable," she whispered. I'll be back in a few with a complete report!"
I settled myself into an easy chair to see what would happen.
Sure enough, as soon as the outside door closed behind Effie, "CC" Crayfish rushed out of my inner office!
