Capítulo 711: Chapter Seven Hundred And Eleven: Interesting Ally

The third point of view:

Deborah didn't let that opportunity pass her by. Jacob Miller was an old man who didn't have much time to live and she treated him so well - even more than his own kids did - that the man was manipulated into marrying her. 

In one word, when Jacob died, Deborah came into possession of forty percent of his properties. His children wedged war against her in the courtroom but Jacob Miller had signed over that huge amount of property to her in his will, hence there was little they could do about it.

Deborah became rich overnight and never for once did she forget her goal of destroying the Spencers. So she left the country where she expanded her resources and influence and years later, returned to the city as a wealthy woman.

Now, Deborah had all the money and resources she needed to fulfill her goal and the first step was to destroy Isabella.
