A saga once more

Down the stairwell, she rolled,
With her, died her secret,
So he thought! but truth be told,
there was something he'd regret.

A mute spectator peering through,
In a roll of film, he caught the action,
He was found by her killer, though,
Beaten, almost dead, pleased at his infraction.

Back to life, slowly was nursed,
By a doctor, who upon him stumbled,
He kept to himself, his lips pursed,
but about a guy, he always mumbled.

A conversation, over the telephone,
About the killer, he overheard,
his ears, he quickly honed,
It was time for action, he feared.

The news caused a stir all over,
His fame shattered by his past,
Over her grave, the mute guy hovered,
Glad, she found her closure, at last!
