Which opening line BEST sets an ominous tone for a short story?

Enjoying her daily walk on the lake trail, Laura headed toward the funny tree that reminded her of her neighbor.

Laura wasn’t sure whether the shadow of a tree or a real person caused her heart to erupt in her chest.

Despite walking this familiar lake trail every day, Laura wasn’t enjoying the view this morning.

Taking her usual morning walk, Laura missed her beloved dog Jack and thought about all the times that he had accompanied her on this very trail.
