Hallie had shrewdly persuaded Giselle that becoming a legal partner in the business might adversely affect Jarrod, effectively positioning herself as the sole proprietor of the salon.

It was essentially a business that Hallie had obtained without contributing a single penny. Following Giselle's unfortunate demise, Hallie was the sole possessor of knowledge regarding the dubious arrangement.

Subsequently, to cover her tracks, Hallie stumbled upon the IOU she had written for Giselle and simply destroyed it, leaving no evidence of the debt she owed.

Jarrod only discovered the absence of his mother's jewelry after her funeral, leading him to strongly suspect Hallie's involvement in its disappearance.

Fortunately, Jarrod's mother had left that notebook behind as evidence. Without it, Jarrod would have remained perpetually ignorant, continuing to regard Hallie as a benefactor while being blind to her duplicity.
