By early afternoon, Mark had driven away to attend his busy legal corporate meetings downtown.
The huge house felt completely quiet except for the ticking clock in the main hallway.
Sarah placed little baby Ella securely inside her plush blue stroller near the upstairs balcony.
She turned around for just a quick second to fetch a clean baby bottle nearby.
Suddenly, a harsh metallic sound echoed violently down the grand wooden upper staircase floor.
Sarah gasped in sudden horror as she saw the stroller rolling rapidly toward the top stair.
Standing right near the top banister was Clara, her hand still pulling back from the handle.
Sarah: Clara, what are you doing, stop that stroller right this instant!
The carriage tipped over the top step, beginning a rapid descent down the hard steps.
Sarah sprinted forward with every single ounce of physical strength inside her terrified body.
She slid hard across the polished marble floor on her knees, stretching her arms out wide.
Her knees slammed painfully into the hard stone floor as she caught the lower stroller frame.
She stabilized the heavy stroller frame tightly just inches before it tipped over completely.
Baby Ella began crying loudly from the sudden sharp movement and scary loud noises.
Sarah: It is okay baby girl, I have got you, you are completely safe now!
Sarah held her heart frantically as tears of sudden terror spilled down her warm cheeks.
Her breath came in heavy, jagged gasps as she unbuckled the terrified crying child safely.
Just at that exact dramatic second, the heavy front entrance doors swung open wide.
Mark walked inside holding his briefcase, stopping dead in his tracks from the loud chaos.
He saw Sarah on the floor holding the crying infant beside the crooked overturned stroller.
Mark: What on earth just happened in here, why is Ella crying like that?
Clara rushed down the wooden stairs with a dramatic, sobbing expression across her face.
Clara: Oh Mark, thank goodness you came home right at this exact terrifying moment!
Sarah: Mark, listen to me carefully, Clara pushed the stroller down the upper steps!
Clara: That is a complete lie, Mark, I saw Sarah drop the carriage myself!
Sarah looked up in absolute disbelief as Clara pointed a sharp finger right at her face.
Sarah: How could you say such a terrible lie when you pushed it yourself?
Mark stepped forward quickly, his face red with sudden rising panic and dark fury.
