Contrary to what Cassidy had been planning for Cecile, her time of retribution came a little earlier.
It was Adrian himself who discovered her crimes two years ago, and without further ado, he had her arrested and locked up in jail. Mia and Anthony had something to do with the whole exposure - they were probably monitoring the mysterious maid all those times. And because of her sudden confinement, she was not able to get any more pieces of jewelry from her.
In the end, Cassidy had failed to fulfill her part in the deal, which she thought was a better outcome in a way. Cecile herself had surrendered despite being the breadwinner of a family whose daily necessities she still had to sustain. She had a lot of regrets at that time, and she sure begged for mercy a lot.
Instead of satisfying her greed, the redhead just decided to look after the needs of those she had left behind.
