Why does sandy mcsouthers fake his death in the westing game?

Sandy McSouther is the door man at sunset towers who working from 22 years as a door man. Sandy's real name is Alexander. He has broad shoulders and stands with his feet spread. He is also Sam Westing, Barney Northrup etc; etc.

He is a door man and claims to have been fired by Westing in the paper mill for something he didn't do. He has a hole between his teeth which allows him to be a very good whistler.


Sandy is also Turtle's (Tabitha Ruth/ T.R Wexler) best friend. She would never kick him. Sandy is usually very happy, cheery, and light. He is Judge Josie Jo's partner in the Westing Game.

Just to point: Sandy is not a real person. Though he is Windy, Julian, Sam, and Barney, only one is real. That one is Windy Windkloppel. How is this inferred?: In earlier chapters, Grace Windsor [Later changed from Windkloppel] Wexler said she was the only true heir to the Westing Mansion, she was related to Westing. But, her maiden name is Winsor, not Westing.

So, Windkloppel was the only real person out of the following: McSouthers, Northrup, Westing, and Eastman. (Please note: North, South, East, West.)
