Model response

Heavy rain pounded the grimy windows of Blackwood Manor tonight.  
Lightning flashed across the darkened sky above the manor house.  
In shadowed halls of Blackwood Manor clock struck midnight sharply.  
Lady Amelia pushed open heavy oak study door slowly.  
She dropped silver tray when she saw the body.  
Lord Blackwood lay face down beside his mahogany desk.  
Crimson pool spread slowly from beneath his battered head.  
Her piercing scream echoed through the mansion's cold marble halls.  
Terrified guests hurried down from bedrooms to witness horror.  
Inspector Graves arrived at dawn amid pouring relentless rain.
