Introducing the central villain of the piece... Dr. Goldman. He is the worst villain I have yet plotting in any story of mine. Yet all the same I am deeply indebted him as—were it not for him—I would not even have this “They Searched Who Laughed” story to record.
What is their motive?
His own safety, for which he, ironically, ends up putting himself in a great deal of danger.
What do they want, and what are they prepared to do to get it?
He wants wealth so that he may be able to stop practicing medicine free of all encumbrances of money matters. To this end, he will literally stop at nothing.
How do they deal with conflict?
He avoids it whenever possible—if he cannot he becomes impatient with it.
Describe their current place of residence.
“Rising she cast her eyes about her and noted where they had been forced to halt. It was directly in front of the most magnificent building upon the street in the form of a mansion of such great and noble diameter, that it might nearly have been mistaken for some wealthy senator's palace. Her spirit lightened, medical aid being nearer than she had before thought; for the palace was that of Dr. Goldman.”
If they were writing this story, how would it end?
If all had gone according to his plan I would not even be writing this story.
What habits, speech patterns, etc. are unique to them?
Except for his pointy mustache (a thing Elise is not likely to fault, concerning her Father's own magnificent specimen) there is nothing in the first perusal of his face or manners that one would be likely to fault. It is only when you have dealings with him that you start to know his coldness.
How do they show love? What do they like to do with/for people they love?
The greatest love he knows is for himself and money and his actions are in line with that.
Do they have any pets?
Perhaps a marmalade or white cat.
Where would they go to relax/think?
His study is where he premeditates some kinds of unthinkable evil, but the rest of it he thinks up on the fly.
What is their weapon of choice? (FYI: words, eyes/looks, and fists count as weapons, too.)
A fist or other blunt instrument applied in just the right place upon the head.
