Elena backed away toward the quiet kitchen doorway area quickly.
Mark did not follow her immediately into the room next door.
He walked over to the home security control panel instead.
The system recorded continuous video around the outdoor pool deck.
Elena noticed what Mark was doing and gasped out loud.
Her calm face turned pale within a single quick second.
Elena: What are you doing with that control screen?
Mark: I am checking the footage from ten minutes ago.
Elena: There is no need to watch any video!
Mark: If it was an accident, the cameras will show it.
Elena lunged forward to grab his wet forearm instantly.
Mark pushed her hand away with a firm motion back.
He tapped the screen to load the backyard video feed.
The clear video showed Elena standing near the pool edge.
Little Lily was playing near the shallow water steps nearby.
The footage showed Elena walking up behind the small girl.
She leaned down toward the child right before the splash.
Mark felt a knot of pure horror tighten inside him.
Mark: You pushed my daughter into that water!
Elena: The video is not clear from that angle!
Mark: I can see your hands on her back!
Elena: It was an honest mistake, I slipped!
Mark: You stood there and watched her struggle underwater!
Elena realized she had nowhere left to run or hide.
Her soft expression turned cold and sharp like glass.
Elena: You were going to leave everything to her anyway!
Mark: Because she is my biological child, Elena!
Elena: I deserved half of this estate and fortune!
