Thomas Allison did call Charlotte Allison, and after some back-and-forth, he basically meant that they were deceived too, acting impulsively, and hoped she wouldn't be angry since they are family and such.
The whole family threatened and bribed someone to take the blame, clearing themselves entirely.
Behind this were the handiworks of Jackson Vance and Nathaniel Hughes.
The Hughes Family started with criminal activities, later prospering in real estate, laundering a portion of their influence, but still holding power on both sides of the law. So Nathaniel Hughes wanting someone to take the fall without any flaws being detected was completely reasonable.
Those who broke into Hazel Allison's room during her birthday party were arranged by Nathaniel Hughes, and later, the Hughes Family got them out after they were caught.
Although Charlotte Allison has had some connections with the underworld over the years, they cannot compare to those of the Hughes Family.
